Abstract
The aim of this study was to evaluate the antibacterial activity of Cymbopogon citratus essential oil against bacteria isolated from the oral cavity of dogs and applied directly to artificially contaminated feed. The commercial dry dog feed received the inoculum of the bacteria prevalent in the oral cavity of the dogs where C. citratus was deposited in the feed by spray. In total, 42 isolates were obtained, 38 Gram-positive and 4 Gram-negative. Staphylococcus spp. was the most prevalent bacteria in the oral cavity of dogs (76.2%). The isolates showed high levels of resistance to different antimicrobials. The minimum inhibitory concentration capable of inhibiting oral bacteria was 0.38 mg/mL. C. citratus essential oil showed positive results with a significant bacterial reduction when applied to feed, signaling the need for further studies to enable its use in the control of pathogens transmitted by animal feed.

Abstract
Background: The objective of this study was to isolate Staphylococcus spp. and to characterize the resistance profile in nasal samples from pigs slaughtered for consumption. Material and Methods: Intranasal swabs were collected from 100 pigs immediately after bleeding in a slaughterhouse located in the largest pork production region in Brazil, these samples were cultured and isolated to identify Staphylococcus spp. in coagulase positive (CoPS) and coagulase negative (CoNS) and molecular identification of Staphylococcus aureus and then subjected to the disk-diffusion test to identify the bacterial resistance profile and search for the mecA gene. Results: Of the 100 samples collected, it was possible to isolate 79 Staphylococcus spp., of these, 72.15% were classified as CoNS and 27.85% of the isolates classified as CoPS. Among the CoPS isolates, 77.27% were identified as S. aureus. Through the disk-diffusion test, it was possible to verify isolates resistant to clindamycin and erythromycin (98.73%), chloramphenicol (93.67%), and doxycycline (89.87%). There was amplification of the mecA gene in 30.38% of Staphylococcus spp. Conclusion: The results of this study highlight the need for the careful use of antibiotics in swine production, in addition to aiming at continuous surveillance in relation to the rate of multiresistant microorganisms within these environments, focused on large industrial centers; such results also indicate the importance of understanding, through future studies, possible pathways to transmission of these microorganisms directly, or indirectly, through meat products derived from these pigs, which can be considered neglected diffusers of variants of Staphylococcus spp. resistant to antibiotics or carriers of important resistance genes related to One Health.

Abstract
OBJECTIVE The aim of this study was to evaluate how relationships between guardians and domestic animals were established and their possible effects during the COVID-19 pandemic period in Brazil. METHODS Data were collected by completing an online questionnaire. Throughout the national territory, 2002 people completed the questionnaire, while respecting social distancing from January 20, 2021, to March 20, 2021. The inclusion and exclusion criteria were 'to own pets' or 'those who had them during the period of quarantine' in Brazil. The data obtained were treated qualitatively through discourse analysis and content analysis, while the quantitative data were tabulated by the questionnaire application platform itself. RESULTS The results showed that 97% of the participants were affected by the coronavirus pandemic in Brazil and that of these, 95.5% stated that their pet was important to overcome and bear bad feelings during the period of social isolation. It was possible to observe through the participants' reports through the online questionnaire that the relationships with their pets were deepened during the pandemic period, and that these had an important role in overcoming bad emotions caused by social distancing. CONCLUSION It was concluded that due to these relationships, behaviors such as anxiety and sadness were reduced and the pets themselves also showed an increase in affective behaviors in relation to their guardians.

Abstract
OBJECTIVE The aim of this study was to investigate the occurrence of the disease and research risk factors through sociodemographic data of children aged 0 to 15 years, with symptoms suggestive of COVID-19 in 3 Brazilian municipalities in an international border region. METHODS Epidemiological and RT-PCR test results were collected from the COVID-19 notification records in suspected children and adolescents from March 1 to August 31, 2020, in municipalities (Assis Chateaubriand, Tupãssi, and Formosa do Oeste) located in an international border region. The results obtained and the variables associated were subjected to statistical analysis using the Chi-Square Test (x2) or Fisher's Exact Test, using the statistical program SPSS v. 21.0 (IBM Corp., Armonk, New York, USA) at the 5% significance level. RESULTS Among the 147 children from the 3 municipalities, 20 (13.60%) were diagnosed as positive. The predominance of cases was in male children (60.00%) and in children living in urban areas (80%). The most frequent symptoms observed in children were fever (65.00% of the cases), followed by headache (60.00%), cough (55.00%), and nasal congestion, as well as sore throat, both found in 35.00% of the cases. CONCLUSION All these data highlight the importance and the need for more epidemiological studies, especially in children and adolescents, as COVID-19 becomes part of the child health panorama worldwide, with serious direct and indirect impacts for humans, animals, and the environment.

Abstract
Periodontal disease is one of the main affections of the oral cavity of dogs. Its main complication is the formation of periapical abscess, which, when affecting the maxillary canine teeth, can lead to the formation of oronasal fistulae. The objective of this study was to evaluate the efficiency of self-curing glass ionomer cement, covered by photopolymerizable adhesive, as a protective element for mucoperiosteal or gingival flap sutures in oral surgery of dogs. We studied 15 dogs from the clinical routine of the dental service of a teaching veterinary hospital, which needed oral surgeries to correct oronasal fistulae, defects or oral cavity communications, regardless of the causal agent. Group one (G1) was composed of seven animals that presented oronasal fistulae after the extraction of maxillary canine teeth compromised by severe periodontal disease. These fistulae were reduced by the double-mucoperiosteal-flap technique, 15 days after the dental extraction. Group two (G2) was composed of five other dogs that presented oronasal fistulae after the extraction of maxillary canine teeth compromised by severe periodontal disease. In this group, the fistulae were reduced by the single-flap technique, immediately after the dental extraction. Group three (G3) was composed of three animals, two of which presented oronasal fistulae due to maxillary fracture and the third one after excision of oral neoplasia. In all groups, simple interrupted sutures were used with 3.0 nylon, and a thin layer of self-curing glass ionomer cement was applied immediately over the operated area. After cement's settling time, a thin layer of photopolymerizable adhesive was applied to the already polymerized cement. In G1, the protective cement was removed on average at 15 (±2) postoperative days, in G2 at 6 (±1) days and in G3 at 11 (±9) days. In the postoperative period, the animals received antibiotics and anti-inflammatory drugs, and they received their usual dry dog food diet. No Elizabethan collar or any other protective measure was used for suturing or the surgical wound. The result was healing of 100% of the oronasal fistulae, without suture dehiscence or the need for new surgical interventions. Thus, it was concluded that the use of self-curing glass ionomer cement covered by photopolymerizable adhesive was fully satisfactory, providing protection of sutures and surgical wounds and showing the potential for routine use in oral surgery in dogs.

Abstract
Gallesia integrifolia, a notable species in the Atlantic Forest, has been traditionally employed in folk medicine for treating rheumatism, asthma, and worms. This study investigated the cellular antioxidant, antiproliferative, and anti-inflammatory activities of the essential oils (EOs) and crude extracts (CEs) from G. integrifolia flowers, fruits, and leaves. The chemical identification of EOs was performed by GC-MS and CEs by UHPLC-MS. Cellular antioxidant and anti-inflammatory activities were assessed through mouse macrophage cell culture. In addition, the antiproliferative potential was evaluated in gastric, colorectal, breast, and lung tumor cell lines and non-tumor VERO cells. EOs predominantly contained organosulfur compounds in flowers (96.29%), fruits (94.94%), and leaves (90.72%). We found the main compound is 2,2'-Disulfanediyldiethanethiol in the EOs of flowers (47.00%), leaves (41.82%), and fruits (44.39%). Phenolic compounds were identified in CEs. The EOs and CEs demonstrated potential against the tumor cell lines tested (GI50 between 51 and 230 µg/mL). The selectivity index values were greater than 1.0 (1.01 to 3.37), suggesting a relative safety profile. Moreover, the anti-inflammatory activity IC50 ranged from 36.00 to 268 µg/mL, and the cellular oxidation inhibition ranged from 69% to 82%. The results suggest that oils and extracts derived from G. integrifolia have potential for use in various industrial sectors.

Abstract
Organic acids (OAs) are a class of feed additives that have prophylactic and inhibitory properties against pathogenic bacteria. In this study, we investigated growth performance, innate immune response, gut microbiota, and disease resistance against Francisella orientalis F1 in Nile tilapia (Oreochromis niloticus) fed different doses of Bacti-nil®Aqua, a blend of short- and medium-chain OAs. For 21 days, 680 juvenile tilapias were fed a control diet or diets supplemented with a 0.3% (D3) or 0.5% (D5) OA blend. The feed conversion rate of fish fed the 0.5% enriched diet was considerably lower (p < 0.05) than that of the fish fed the basal diet. Lysozyme and serum bactericidal activities were significantly elevated following OA administration. After infection, no differences in the diversity and composition of gut microbiota were observed between the groups. After the bacterial challenge, the mortality was significantly lower in group D5 (p < 0.01). The diet supplemented with Bacti-nil®Aqua (Adisseo) improved the immune response and resistance of tilapia juveniles against F. orientalis infection. Thus, this OA blend could serve as a feed additive with good activity against F. orientalis.

Abstract
Bovine mastitis is an inflammation of the mammary gland in response to invasion by opportunistic agents. Due to the high economic importance of dairy production and the complexity related to animal health, the objective of this work was to identify and evaluate the antibacterial resistance profile of samples of mastitis milk, milking hand and milking equipment from small rural dairy farms belonging to the northwest region of the state of Paraná, Brazil. Five small, non-technical dairy farms in the municipalities of Boa Esperança, Juranda and Tapejara, all belonging to the northwest region of the state of Paraná, Brazil, were selected. The properties had Holstein and/or crossbred herds, carried out a bucket-by-foot milking system and all had the presence of animals with subclinical mastitis confirmed by the California Mastitis Test. Samples of sterile swabs from the milking insufflators, the milking hand and milk samples were collected-and later, isolation tests and phenotypic characterization of the samples, sensitivity tests to antimicrobials and phenotypic tests for the detection of beta-producing strains were performed with extended-spectrum beta-lactamase (ESBL), molecular identification of Staphylococcus aureus isolates and mecA gene research. Of the 199 samples collected from the 15 selected properties in the municipalities of Boa Esperança, Tapejara and Juranda, 72 (36.20%) were classified as multiresistant. Isolated from milkers' hands and milking machines, which phenotypically produce extended-spectrum beta-lactamase (ESBL), the presence of the mecA gene was also observed in 11 isolates of Staphylococcus spp. of milk samples, machines and milking hands. Mastitis can be spread to the herd through the milking process by the milkers' instruments and hands, and adequate management measures can prevent its transmission and the conscious use of antibiotics decreases the prevalence of multidrug-resistant pathogens. In this work, different pathogenic bacteria were detected in mastitic milk, milking equipment and milking hand with a high percentage (36.20%) of isolates classified as multidrug resistant. In addition, the presence phenotypically (ESBL) and molecularly (mecA gene) of isolates carrying resistance genes was also verified. These results directly reflect on the health of the animals, the health of the workers and the health of the respective environment, which can enable the continuity of the propagation of the etiological agents involved in the mastitis infection. The awareness of producers and workers on these properties about the disease, transmission, sanitary aspects and adequate management and treatment are essential for improving milk production and production efficiency.

Abstract
Around the world, the main problems of livestock are caused by ectoparasites, however, commercial acaracide are toxic to the environment and detrimental to One Health. Therefore, research has increasingly focused on development of natural products as alternatives for tick control. The purpose of this study was to evaluate the larvicidal effect on Rhipicephalus (Boophilus) microplus, through use of essential oils (EOs) extracted from the leaves, flower buds and stems of Tetradenia riparia. The chemical composition of these EOs was determined through gas chromatography coupled to mass spectrometry (GC-MS). They were tested on larvae at concentrations of 100.000 to 40 µg/mL, using the larval packet test and under semi-natural conditions. The main class of compounds in the chemical composition was sesquiterpenes (both oxygenates and hydrocarbons), whereas the predominant compounds in the leaves, flower buds and stems were 14-hydroxy-9-epi-caryophyllene, T-cadinol and 6-7-dehydroroyleanone, respectively. The leaves proved to be the most effective, with highest larvicidal activity (LC99.9 = 83.53 µg/mL). When tested under semi-natural conditions, the oils obtained efficiency above 98% in all compound tests. The results indicated that these EOs were effective against R. (B.) microplus larvae in vitro and ex-situ, proving that this plant has bioactive molecules with significant larvicidal activity.

Abstract
The presence of Staphylococcus spp. resistant to methicillin in the nasal cavity of swine has been previously reported. Considering the possible occurrence of bacterial resistance and presence of resistance genes in intensive swine breeding and the known transmissibility and dispersion potential of such genes, this study aimed to investigate the prevalence of resistance to different antibiotics and the presence of the mecA resistance gene in Staphylococcus spp. from piglets recently housed in a nursery. For this, 60 nasal swabs were collected from piglets at the time of their housing in the nursery, and then Staphylococcus spp. were isolated and identified in coagulase-positive (CoPS) and coagulase-negative (CoNS) isolates. These isolates were subjected to the disk-diffusion test to evaluate the bacterial resistance profile and then subjected to molecular identification of Staphylococcus aureus and analyses of the mecA gene through polymerase chain reaction. Of the 60 samples collected, 60 Staphylococcus spp. were isolated, of which 38 (63.33%) were classified as CoNS and 22 (36.67%) as CoPS. Of these, ten (45.45%) were identified as Staphylococcus aureus. The resistance profile of these isolates showed high resistance to different antibiotics, with 100% of the isolates resistant to chloramphenicol, clindamycin, and erythromycin, 98.33% resistant to doxycycline, 95% resistant to oxacillin, and 85% resistant to cefoxitin. Regarding the mecA gene, 27 (45%) samples were positive for the presence of this gene, and three (11.11%) were phenotypically sensitive to oxacillin and cefoxitin. This finding highlights the importance of researching the phenotypic profile of resistance to different antimicrobials and resistance genes in the different phases of pig rearing to identify the real risk of these isolates from a One Health perspective. The present study revealed the presence of samples resistant to different antibiotics in recently weaned production animal that had not been markedly exposed to antimicrobials as growth promoters or even as prophylactics. This information highlights the need for more research on the possible sharing of bacteria between sows and piglets, the environmental pressure within production environments, and the exposure of handlers during their transport, especially considering the community, hospital, and political importance of the presence of circulating resistant strains.

Abstract
Horses can contribute to the spread of bacterial diseases, which can be caused mainly by, Staphylococcus spp., which are part of the animals’ commensal microbiota, but it is also considered a pathogenic microorganism capable of causing serious infections. vancomycin, when it is resistant to methicillin. Antimicrobial resistance is considered a major health problem by the World Health Organization and the emergence of the mecA gene, responsible for resistance to the class of beta-lactam antibiotics. Thus, the aim of this work was to investigate the antimicrobial resistance profile and the presence of the mecA gene in Staphylococcus spp. isolated from the nasal, oral and auricular microbiota of horses used as animal traction on small family farms. Nasal, oral and auricular swabs were collected from 38 horses, with 29 (76.3%) isolated in nasal swab, 15 (39.4%) in auricular swab and 9 (23.6%) in oral swab, totaling 53 Staphylococcus spp. and 50 (94.33%) samples were resistant to the 11 antimicrobials tested, none of which were positive for molecular tests to identify the mecA gene. The results demonstrate the presence of Staphylococcus spp. associated with high (94.33%) bacterial resistance, indicating that horses can be considered reservoirs of multi-resistant microorganisms.

Abstract
Baccharis dracunculifolia DC (Lamiaceae) (Asteraceae) is found in South America, mainly in Argentina, Brazil, Bolivia, Paraguay and Uruguay. Folk medicine is used as a sedative, hypotensive, bronchodilator, cardiovascular disorders, anti-flu, and also in skin wounds. Considered the main source of green propolis, which increases the pharmacological interest in this species. It is also known as a "benefactor" plant facilitating the development of other plant species around it, being indicated for the recovery of degraded areas. This species has been studied for decades in order to isolate and identify the active principles present in the aerial parts (leaves and flowers) and roots. The present study consists of a review of the scientific literature addressing the ethnobotanical, ethnomedicinal, phytochemical, pharmacological and potential cytotoxic effects of the B. dracunculifolia species. In this survey, we sought to investigate issues related to the botanical and geographic description of the species, the ethnobotanical uses, as well as the phytochemical studies of the essential oil, extracts and green propolis obtained from the aerial parts and roots of B. dracunculifolia. Using high precision analytical tools, numerous compounds have already been isolated and identified from leaves and flowers such as the flavonoids: naringenin, acacetin, dihydrokaempferol, isosakuranetin and kaempferide; phenolic acids: p-coumaric, dihydrocoumaric, ferulic (E)-cinnamic, hydroxycinnamic, gallic, caffeic, and several caffeoylquinic acids derivatives; phenolic acids prenylated: artepillin C, baccharin, drupanin; the glycosides dracuculifosides and the pentacyclic triterpenoids: Baccharis oxide and friedelanol. The predominant class in the essential oil of leaves and flowers are terpenoids comprising oxygenated monoterpenes and sesquiterpenes, highlighting the compounds nerolidol, spathulenol, germacrene D and bicyclogermacrene. These compounds give the species high antimicrobial, antioxidant, antitumor, analgesic, immunomodulatory and antiparasitic potential, making this species a promising herbal medicine. In vitro toxicity assays with B. dracunculifolia extract showed low or no cytotoxicity. However, in vivo analyses with high doses of the aqueous extract resulted in genotoxic effects, which leads us to conclude that the toxicity of this plant is dose-dependent.

Abstract
Objective: The objective of this work was to adapt a diagnostic kit developed for humans to identify Dengue (DENV1, DENV2, DENV3, DENV4), Zika (ZIKV) and Chikungunya virus (CHIKV) in females of Aedes aegypti and Aedes albopictus and to verify if the occurrence of mosquitoes infected with these three arboviruses are being found in regions with high occurrence of these diseases in humans. Materials and Methods: For this purpose, live mosquitoes were captured between January and June 2020 using 3,476 traps permanently installed in the field were used. After capture, the species were identified, then the females were placed in a pool of 2 to 10 specimens and sent to the laboratory for detection of DENV1, DENV2, DENV3, DENV4, ZIKV and CHIKV by RT-PCR using a commercial human kit for arboviruses. Results: Of the 76 mosquito pools collected, six (7.9%) pools tested positive for the DENV2 virus. The DENV-positive mosquitoes were collected in regions with a high incidence of reported cases of Dengue or in adjacent areas. Conclusion: The absence of kits for the detection of these arboviruses in Aedes is a limiting factor and the adequacy of commercial kits, already used for the diagnosis of arboviruses in humans, the results presented demonstrate that it is possible to identify the presence of DENV2 in mosquitoes with the respective kit, reinforcing the use of RT-qPCR as a robust diagnostic tool for epidemiological surveillance allowing managers to receive timely results for decision-making regarding prevention and control actions.

Abstract
The aim of this study was to verify the bacterial resistance profile and detect the presence of mecA gene in Staphylococcus spp. isolated from the nasal microbiota of domiciled dogs. For this purpose 100 nasal swabs from 100 domiciled dogs were collected from the central area of the city of Umuarama (PR), along with a questionnaire answered by their owners. After the isolation all Staphylococcus spp. isolates were submitted to the diffusion disc test by the Kirby-Bauer method, and only oxacillin-resistant samples were submitted to the PCR technique to search for the mecA gene and the results were then submitted to statistical analysis to verify possible risk variables. The 100 Staphylococcus spp. and coagulase negative, among which 41 isolates were resistant to oxacillin, no samples were positive for the mecA gene presence, however, 12 resistant to vancomycin were found. It can be concluded that the domiciled dogs are carriers of Staphylococcus spp. multiresistant, being these a possible source of human contamination.

Abstract
In the present study, we evaluated the effects of administering Enterococcus faecium in food and/or water on the hematological and immunological parameters, intestinal microbiota, resistance to bacterial diseases (streptococcosis and francisellosis) and growth of Nile tilapia. Before the in vivo experiment, probiotic bacteria isolated from Nile tilapia were selected via inhibition tests. Sequencing, annotation, and assembly of the complete genome of the selected bacteria as well as other tests were performed using bioinformatics tools. Three treatments were implemented: G1 (probiotic feeding), G2 (probiotic in water), and G3 (probiotic in food and water); and a negative control (NC) was also employed. Treatment lasted 38 days, and each group consisted of fish and two repetitions. The fish were divided and infected with Streptococcus agalactiae S13 (serotype Ib) and Francisella orientalis. The G1 group had a higher average final weight gain than the G2, G3, and NC groups. Further, a significant increase in the number of thrombocytes was observed in the groups administered probiotics in the diet (G1 and G3). A statistical difference was observed in the mortality of fish infected with S. agalactiae in the NC compared to the treated groups. Cetobacterium was the 43 most abundant genus in the intestinal microbiota of all groups, including the NC group. E. faecium increased the immunity of fish administered the treatment and decreased the mortality caused by S. agalactiae. As an autochtone probiotic, E. faecium does not interfere with the local ecosystem and thus has a great probiotic potential for Nile tilapia in Brazil.

Abstract
Leptospirosis is an important infectious disease, which can generate large economic losses, especially in the dairy herd. The pathogen that causes this disease may have its entry in Brazilian herds facilitated by the existence of a large extension of land borders. Therefore, the objective of this work was to investigate the presence of DNA and antibodies against Leptospira spp. in samples of vaginal mucus and serum from naturally infected bovine females from small rural dairy farms in a border region. Blood and vaginal mucus samples were collected from 70 Holstein cows, from small rural dairy farms between October 2017 and June 2018. The inclusion criteria for dairy cattle of any breed were aged over 2 years, not vaccinated against leptospirosis, and presenting a history of any reproductive problem such as abortion, stillbirth, repetition of heat, absence of heat, and lack of conception. Blood was collected by puncturing the coccygeal vein; for the collection of vaginal mucus, it was necessary to use a tampon with an applicator. For the detection of anti-Leptospira spp. antibodies, the sera were submitted to microscopic agglutination test (MAT) and, for DNA detection, the vaginal mucus was submitted to the PCR technique. Among the 70 cows, 42.86% had reagents in MAT and the most likely serovar was Wolffi (43.47%). In 74.28% of the vaginal mucus samples, it was possible to amplify the Leptospira spp. DNA. The results of this work show the presence of Leptospira spp. antibodies and DNA in samples of serum and vaginal mucus from naturally infected bovine females from small rural dairy farms in a border region (Brazil × Paraguay). These results demonstrate the importance of considering bovine females as potential vaginal carriers of Leptospira spp. Thus, it highlights the importance of further studies to better understanding of this issue, in addition to carrying out molecular and serological tests, to monitor the infection and further characterize epidemiological studies of leptospirosis in herds from regions that face this international frontier challenge.

Abstract
The Iguaçu National Park (INP) is the largest remnant of Atlantic Forest in southern Brazil, representing an ecological continuum with Argentina. The INP harbours a diverse fauna, with ring-tailed coatis (Nasua nasua Linnaeus, 1976, Carnivora: Procyonidae) in close contact with tourists either begging and/or snatching food from visitors. A potentially novel haemotropic Mycoplasma sp. has been previously detected in the ring-tailed coatis from central-western and southern Brazil. Therefore, the aims of this study were to investigate the occurrence of haemotropic Mycoplasma sp. and tick-borne pathogens in wild ring-tailed coatis from the INP, Foz do Iguaçu municipality, Paraná State, southern Brazil. Blood samples were collected from 18 wild ring-tailed coatis and evaluated by conventional PCR (cPCR) assays for haemotropic Mycoplasma spp. (16S and 23S rRNA), Theileria/Babesia spp. (18S rRNA) and Ehrlichia/Anaplasma spp. (16S rRNA, sodB, dsb and groEL). Eight out of 18 (44.44%; 95% CI: 24.56%-66.28%) animals were positive for haemotropic Mycoplasma spp. All ring-tailed coatis tested negative for Theileria/Babesia spp. and only one out of 18 (5.56%; 95% CI: 0.99%-25.76%) animals tested positive for Ehrlichia/Anaplasma spp. by the 16S rRNA cPCR. Unfortunately, multiple attempts to sequence the 16S rRNA gene of the Ehrlichia/Anaplasma-positive sample have failed. Phylogenetic and network analysis of the hemoplasma 16S and 23S rRNA gene fragments confirmed that animals were infected by a potentially novel haemotropic Mycoplasma sp. previously reported in ring-tailed coatis from Brazil. The name 'Candidatus Mycoplasma haematonasua' is proposed for this novel organism.

Abstract
The aim of this study was to investigate the presence of Leishmania sp. DNA and anti-Leishmania spp. antibodies in free-ranging Sapajus nigritus from an urban forest located in a city in the North Central region of the state of Paraná. For the indirect diagnosis, the direct agglutination test was used with promastigote forms of Leishmania (V.) braziliensis, where it was possible to detect the agglutination reaction in 53.33% of the S. nigritus blood samples. For direct diagnosis, the samples were submitted to real-time quantitative polymerase chain reaction, which confirmed the presence of Leishmania spp. DNA in 26.66% of the tested samples. It reinforces the importance of considering the concept of One Health in the face of diseases with high prevalence, such as leishmaniasis and the need for health education measures. This result shows that the animals in the present study have a role as environmental bioindicators for leishmaniasis.

Abstract
Infections caused by Edwardsiella ictaluri are one of the biggest problems in the catfish industry in North America and have been reported in fishes around the world. E. ictaluri was detected in juvenile pintado Pseudoplatystoma corruscans-a Brazilian catfish-in a farm in Paraná State, Brazil; diseased animals showed ascites and neurological signs of infection, with more than 50% mortality. Exotic invasive species susceptible to this bacterium have been reported in this area. We assessed the susceptibility of pintado to E. ictaluri with experimental infection via intraperitoneal and immersion methods as well as a cohabitation experiment with Nile tilapia Oreochromis niloticus and African walking catfish Clarias gariepinus, 2 exotic invasive species. All pintados challenged by intraperitoneal and immersion routes and those cohabiting with infected C. gariepinus died within 17 d of the challenge. Mortality of Nile tilapia reached 71.42% after the intraperitoneal and 35.71% in the immersion challenges within 28 d, whereas African walking catfish showed zero mortality. Observed clinical signs were comparable to those in the farm and those described in the literature as enteric septicemia of catfish. With this study, we demonstrated the susceptibility of P. corruscans to E. ictaluri, as well as interspecies transmission of this bacterium.

Abstract
The presence of DNA and anti-Leishmania spp. antibodies in the serum of 112 healthy horses was investigated by evaluating the physical examination, from a rural society located in the north central region of Paraná. The antigens of Leishmania amazonensis, Leishmania braziliensis, and Leishmania infantum were used to perform the indirect enzyme-linked immunosorbent assay, where it was possible to detect the reaction in 27.67% of the samples. These were also subjected to the real-time quantitative PCR, which confirmed the presence of Leishmania spp. DNA in 67.34% of the tested samples. The results show that the tested animals were previously exposed to the protozoan. Thus, these animals can be considered environmental bioindicators of the presence of Leishmania spp. at the study site. The material used in this study (serum), although not ideal, proved to be effective and less invasive. Taking into account the importance of the disease, the absence of more in-depth information on the species, the high zootechnical value of these animals, and their strictly close contact with the urban area and the human species, it is essential that further studies are carried out to elucidate the epidemiological profile of them in the face of the disease, as well as the possibility of them acting not only as hosts but also as reservoirs.

Abstract
Background: Cutaneous asthenia or Ehlers-Danlos syndrome is an inherited and rare disease. This infirmity is from an autosomal mutation that influences the collagen synthesis of the carrier. Thus, its skeleton, formed of fibers, is structurally defective. The disease is characterized by hyperelasticity and skin fragility, leading to lesions throughout the skin. The lesions may manifest in specific places or in a generalized way, being more frequent in the limbs, neck, and back. This disease does not have a specific treatment, only management care to avoid new traumas.Case: A 3-year-old male castrated, no defined race cat, was attended at one veterinary clinic with a history of intense itching. The rapid tests for feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) were negative. On physical examination, infestation by fleas, lesions all over the body, and skin hyperelasticity were observed. Topical treatment for ectoparasites as well as for body wounds was established. After the treatment, he returned without itching, but with the complaints of new lesions that did not heal. The patient underwent a total shearing to facilitate the treatment of the skin, and then he underwent blood tests, biochemistry, hormonal tests, and ultrasound, which showed no suggestive changes for hyperadrenocorticism and diabetes mellitus. His clinical signs, besides not matching with these diseases, also did not indicate skin fragility due to his history of age and balanced diet. The confirmation of the cutaneous asthenia syndrome was acquired through biopsy of skin fragment, in which it was observed disarray of collagen fibers, hypertrophy, and fibroblast hyperplasia, together with the rate of extensibility of the skin where the value reached the mark of 27.5%. Throughout the hospitalization, it was noted the progression of the disease with the appearance of new lesions, where there was no bleeding and they appeared even with the patient wearing padded clothes. Its progression lasted one year until the patient's euthanasia.Discussion: For the disposal of diabetes mellitus and hyperadrenocorticism as causes of the appearance of lesions by the body in the patient, he was submitted to the suppression tests with dexamethasone, in which he presented normality, in the biochemical examination it was dosed with fructosamine and glucose. The fructosamine was in the reference value, but the glucose was slightly altered, this increase may have been a result of stress at the time of blood collection. In addition to the patient not showing specific clinical signs such as polyphagia, polyuria, polydipsia, and weight loss, these are characteristic clinical signs of the disease. For the diagnosis of Ehlers-Danlos syndrome, histological examination, and calculation of the skin extensibility index were used, where the results obtained confirmed the suspicion. This genetic anomaly has no treatment, being progressive, so only environmental management is done to mitigate the appearance of the lesions and provide animal welfare. This case report contributes to aggregating the scientific literature in the area of veterinary medicine since skin asthenia is a rare disease and when its extent is total it becomes even more atypical. The availability of this article will provide a vision of palliative treatment for other cases, demonstrating the progressive nature of the lesions and the methods of diagnosis. Keywords: cat, collagen deficiency, ehlers-danlos syndrome, hyperelastic, skin.

Abstract
Background: Anophthalmia is a rare, congenital condition, defined as the complete absence of the eye bulb due to inadequate growth of the vesicle or optic dome. The malformation can be primary (in the absence of complete), secondary (in the presence of only residual tissue), or degenerative (in which the eye begins to form, but for some reason, it begins to degenerate). This condition is rare in dogs, cats, cattle, and sheep. Microscopic evaluation of orbital tissue for identification is always recommended. The aim of this study was to report a case of bilateral anophthalmia in a domestic cat.Case: A feline male, healthy, Maine Coon breed with 60 days of life was attended at the one veterinary private clinic. The cat, negative for FIV and FeLV, was born in a commercial cattery, belonging to his mother's third litter, healthy litter with the exception of this feline. He arrived with a complaint of not opening his eyelids, like the rest of the litter. In the clinical examination, it was found the normality of vital signs, absence of other visible anatomical abnormalities, only the ocular region was observed with closed eyelids. The initial suspicions were anophthalmia and microphthalmia. The patient was referred for an ocular ultrasound, which showed the complete absence of the right and left eye bulbs. The right and left orbital cavities had only a volume of soft, amorphous, and predominantly homogeneous tissue. After the ultrasound report, the patient underwent a surgical procedure to remove a fragment of tissue from the eye socket, which was sent for histopathological examination to confirm anophthalmia and discard the differential diagnosis of microphthalmia. Microscopy revealed immature, epithelial, and glandular tissue in the middle of discrete and moderate connective tissue, loosely arranged. In some fragments, cartilaginous tissue was also revealed. Thus, the histological findings are compatible with immature, pseudoformed tissues and without neoplastic characteristics. The diagnosis of secondary anophthalmia was reached with use of ultrasound and histological reports.Discussion: Congenital malformations in domestic cats are less frequent than in dogs, some of which are rare, and little reported. Secondary anophthalmia in the reported patient was confirmed by histological and ultrasound examination. Bilateral secondary anophthalmia is characterized by the absence of the eyeball, but with the presence of adjacent tissue. The animal was submitted to an ocular ultrasound examination and the complete absence of ocular bulbs was found. The differential diagnosis of microphthalmia was ruled out because there was no evidence of the eyeball. Microphthalmia is a common congenital ophthalmic disorder in veterinary medicine. Representative fragments were submitted to histopathological examination, where immature, epithelial tissue was found. In some fragments sent for analysis, cartilaginous tissue was observed. The histological findings are compatible with immature, pseudoformed tissues, thus verifying bilateral congenital anophthalmia in the reported animal. The clinical examination in these cases serves to ensure that the animal does not have any other congenital changes, allowing a favorable prognosis in puppies. Based on the information presented, the animal in this study has bilateral secondary congenital anophthalmia, with a favorable prognosis for the patient to live with certain normality, with quality and well-being.

Abstract
The objective of this research was to determine the antimicrobial resistance of bacteria isolated from items related to hygiene and antisepsis, equipment, and instruments used in different hospital wards. Bacterial isolation and identification, phenotypic antimicrobial susceptibility assays, mecA gene detection, and multiple antimicrobial resistance index analysis were performed. In total, 105 bacteria were isolated from 138 items. Of these, 49.52% bacteria were collected from instruments, 43.80% from equipment, and 6.66% from items related to hygiene and antisepsis. All gram-positive bacteria (88 isolates) were identified as coagulase-negative Staphylococcus. Five species of gram-negative bacilli (17 isolates) were isolated, and the prevalence of Enterobacter agglomerans (29.41%), Escherichia coli (11.76%), and Serratia liquefaciens (11.76%) was high. Antimicrobial resistance was reported for 93.33% of the isolates. Gram-positive bacteria were resistant to sulfazotrim (88.64%) and penicillin (82.95%), while gram-negative bacteria showed resistance to sulfazotrim (70.59%) and ampicillin (64.71%). Analysis of multiple antibiotic resistance index showed that 73.33% of the isolates were a high risk to public health. The mecA gene was detected in 23 (71.88%) isolates. The evaluation of microorganisms isolated in the hospital environment revealed their high multidrug resistance index. Thus our study presses the need to pay more attention to the cleanliness of frequently used instruments, which may be potential sources of infections.

Abstract
OBJECTIVE In Brazil, the most common method of controlling outbreaks of arbovirus is by the use of chemical sprays, which kill the insect vector, Aedes aegypti. The main objective of this study was to evaluate the resistance of Ae. aegypti to the insecticide, malathion, in situ. The location of this study was the municipality of Foz do Iguaçu, in the state of Paraná, Brazil. METHODS Ultra-low-volume (ULV) fogging equipment was used, by vehicle, to apply the insecticide in situ, and mosquito populations after treatment were compared with those of control areas. The resistance of strains collected from the municipality was compared to the Rockefeller strain under laboratory conditions. RESULTS We found 220 adult female specimens and 7423 eggs of Ae. aegypti in the areas subjected to UBV treatment, whereas 245 adult females and 10 557 eggs were found in the control areas. The UBV treatment area showed no significant difference compared to the control area, for all the indices. Mortality of the Rockefeller colony varied more quickly when there were slight variations in malathion concentration than the Foz do Iguaçu population.

Abstract
The aim of this study was to evaluate the profile of antimicrobial resistance in members of the family Enterobacteriaceae and to detect strains of extended-spectrum beta-lactamases (ESBL) in free-living Sapajus nigritus. Oral and rectal swabs were collected from 15 primates to isolate and identify bacteria, conduct phenotypic tests to detect antimicrobial sensitivity and ESBL-producing strains, and calculate the multiple antimicrobial resistance index. The least effective antimicrobial was amoxicillin (72.72%) and ampicillin (57.57%), and the samples were considered as high risk for public health. No sample was positive for ESBL production. The results show that this study is relevant to One Health initiatives, considering the possibility of transmission of bacterial resistance and resistant genes originating from direct or indirect interaction of S. nigritus with parkgoers. However, these animals cannot be considered as the only reservoirs and transmitters of resistant bacteria as they can be contaminated by human-origin bacteria that can be extremely harmful and often prove lethal to them that play an important role in relationship to the ecology, spreading seeds and controlling insects.

Abstract
Background: Contact between humans and pets, mainly dogs and cats, has been increasing in recent years, which may result in the spread of infectious agents to new hosts and even to the environment, causing emergencies of national and international interest. The aim of this work was to understand the phenotypic profile of bacteria of the Enterobacteriaceae family of vaginal and preputial mucous of stray dogs from a border region.Materials, Methods & Results: Swab samples from the vaginal and preputial mucosa of stray dogs from two border regions were collected for later bacterial isolation, biochemical identification of bacterial isolates, susceptibility tests to different antimicrobials, and determination of the bacterial resistance index. Samples were collected from 70 animals, was possible to isolate 88 samples, of which 36 (40.9%) presented isolates of Gram-negative bacteria, with Escherichia coli being the most prevalent species (44.8%), followed by Obesumbacterium proteus in eight (27.5%); Enterobacter aerogenes and Enterobacter cloacae in two (6.8%); and Erwinia herbicola, Koserella trabulsii, Proteus mirabilis, and Serratia rubidaea (3.4%) from one isolate. The most resistant antimicrobials Clindamycin (100%), Metronidazole (100%), Oxacillin (100%), and Penicillin (100%) were tested against the vaginal and preputial samples and when the multidrug resistance index of the isolates was analyzed, all were classified as presenting a public health risk.Discussion: The results of this work suggest that stray dogs may be considered potential reservoirs of resistant pathogenic microorganisms, enabling future health problems due to the close coexistence of tutors with their dogs. It is known that the microorganisms that inhabit a certain environment or a specific part of the body are collectively called microbiomes. More specifically, some of them are bacteria that inhabit the reproductive mucous membranes (vaginal and preputial) of healthy dogs. Several works have also identified E. coli as the most prevalent bacteria identified in the vaginal and preputial mucosa of healthy dogs, that is regarded as a member of different microbiomes that is a commensal of different species of domestic animals, it is important to stress that this bacterial species presents sophisticated virulence mechanisms possibly responsible for different nosocomial infections as well as community infections in mankind and different species of animals. Found other bacterial species suggests a connection of these bacterial species with different environments and different animal species, which is even more disturbing regarding public health, since most of the time dogs share the same spaces of their tutors, which would facilitate the transmission and interaction with potentially pathogenic microorganisms. The MAR index result is worrying when dealing with stray and asymptomatic dogs, since the behavioral particularities of canine species such as licking the body, licking the genitalia, sniffing the environment for territorial demarcation and, in some cases, coprophagy, may facilitate the transmission of pathogenic microorganisms and even disseminate genes of resistance to their keepers, other animals, and even to the environment. Unique health education works should be conducted in border regions in order to raise awareness of the population involved about the different situations that may favor the dissemination of microorganisms and their resistance genes, including the problems caused by the illegal sale and/or transportation of drugs, a situation that is very common in borders.

Abstract
Background: Studies on intestinal parasites in cougars Puma concolor are scarce, and most of the available information on the species has been derived from individuals in captivity. One of the greatest threats to the survival of wild cats is habitat loss caused by urban sprawl, agricultural matrix, and linear developments such as highways and railways, which expose animals to direct contact with humans and to a high risk of death. Given the lack of scientific data the objective of this study was to report on the occurrence of intestinal parasites in a cougar (P. concolor) specimen from the northwestern region of Paraná State, Brazil.Case: The carcass of a free-living cougar (P. concolor) individual was sent to the Interdisciplinary Science Museum (Museu Interdisciplinar de Ciências – MIC) of Paranaense University (Universidade Paranaense - UNIPAR); an individual was killed during a collision with an unidentified vehicle on highway PR-486, in the municipality of Mariluz (PR, Brazil). The geographical coordinates of the location where the animal was found are: 23°59′29″S, 53°8′47″W. This region is characterized by semi-deciduous seasonal forest remnants. After being identified on site and collected by the inspectors of the Paraná Environmental Institute (Instituto Ambiental do Paraná - IAP), the cadaver was donated to the MIC (by the IAP) for a necropsy to elucidate the cause of death. In this context, the cadaver was sent to the Animal Pathology section of the Department of Veterinary Medicine at UNIPAR. The animal was necropsied by performing the standard necropsy technique for carnivores: opening the intestine through the mesentery and exposing the mucosa from the duodenum to the colon. The necropsy showed that the cause of death was hypovolemic shock due to trauma. During necropsy, parasites in the intestinal lumen were visible to the naked eye. Parasites and feces were collected and stored in sterile flasks containing 10% formaldehyde and saline. The parasites were subjected to Faust and Hoffman techniques, micrometry, and morphological analysis, resulting in the identification of the roundworm Toxocara cati and the tapeworm Spirometra decipiens.Discussion: Identifying the roadkill species along highways is of paramount importance, since they are living very close to man and, consequently, reservoirs and disseminators of different infectious and parasitic zoonoses may be possible. Infection by protozoa and helminths in animals usually occurs by ingesting the infective form present in food or water. Toxocara cati and the tapeworm Spirometra decipiens were only reported in captivity before. Research on parasites in free-living wild animals is not common in the scientific literature and this is due to the difficulty of capturing this animal category as they live in difficult to access places such as forests and forests, therefore, research projects in partnership with museums are extremely important for the recognition of wild animal species that circulate in the region, in addition to the parasitic identification of these animals for future sanitary measures and for the preservation of the animal species in the environment. The Parasitological studies of wild animals are highly relevant for expanding this knowledge, especially considering the possible transfer risk of specific parasitic diseases to other animals, as well as to humans.

Abstract
Devido ao uso de antibióticos para o tratamento e prevenção de infecções bacterianas durante a produção de matrizes pesadas, torna-se importante estudar o perfil de resistência e a prevalência de bactérias gram-negativas produtoras de ESBL. Dentre as várias classes de antimicrobianos disponíveis, destacam-se os agentes beta-lactâmicos, categoria antimicrobiana amplamente utilizada em clínica médica humana e veterinária. Assim, este trabalho teve como objetivo avaliar o perfil de resistência e caracterizar as cepas produtoras de beta-lactamases de espectro estendido (ESBL) isoladas de matrizes de corte por meio da coleta de 87 swabs cloacais. As bactérias Gram-negativas foram isoladas em meios seletivos, identificadas por métodos bioquímicos convencionais e MALDI-TOF® e estudadas quanto à resistência antimicrobiana, incluindo ESBL. Das 87 amostras, foram isoladas 52 bactérias gram-negativas. Houve alta resistência bacteriana às principais classes de antimicrobianos utilizados em aves: penicilinas, cefalosporinas e quinolonas. Também foi encontrado fenótipo sugestivo de produção de ESBL em 42,31% dos isolados, demonstrando resistência aos antimicrobianos beta-lactâmicos testados. Os resultados demonstram a necessidade de orientação dos profissionais que trabalham com matrizes de corte, a fim de se reduzir a presença de bactérias resistentes e produtoras de ESBL e evitar sua disseminação para o meio ambiente, ovos férteis e frangos de corte e, consequentemente, carne de frango e humanos.

Abstract
Human cases of dengue virus based on the National Dengue Control Plan were compared with the molecular detection of the dengue virus in trapped mosquitoes, verifying the prediction and efficacy potentials of vector control between the two methodologies in a city with three endemic frontiers. Molecular detection of dengue virus in trapped mosquitoes was significantly higher than in human cases (p = 0.0435). Thus, molecular detection could be used as an early indicator to help prevent more human cases of dengue.

Abstract
Background: In Brazil, cats in households has recently increased dramatically, likely due to their lower space and care requirements. We need to know the health of these companion animal species, since they have behavioral patterns that make them an important link in the epidemiological chain. Extended spectrum beta-lactamase producer strains (ESBL) are resistant to penicillin, cephalosporin and monobactam, but they are susceptible to clavulanate. The goal of this study is to detect strains of Enterobacteriaceae that produce extended spectrum beta-lactamase (ESBL) and evaluate the bacterial resistance profile in isolated cats (Felis silvestris catus) that live in a city located at west of Parana state, Brazil.Materials, Methods & Results: Swabs were aseptically collected from the anal orifice and oral cavity of 49 female domestic cats that were healthy upon clinical and physical examination, a minimum age of one year, weighing up to 3 kg, and had attended a veterinary clinic specializing in cats, in order to, later, perform the isolation and bacterial identification, antimicrobial sensibility phenotypic test and the phenotypic test to detect ESBL producer strains. From the 98 swabs collected it was possible to perform the bacterial isolation in 68 samples; 40.81% isolated from anal orifice and 28.57% isolated from oral cavity. From rectal and oral cavities 77.50% and 71.42% of the isolated were identified as Escherichia coli respectively, being 2.94% considered ESBL producer strains. In relation to bacterial resistance the antibiotics that shown more resistance in anal orifice were ampicillin, amoxicillin, nalidixic acid, sulfazotrim, tetracycline and aztreonam. In oral cavity they were ampicillin, amoxicillin, cefoxitin, amoxicillin + clavulanate, aztreonam, ceftriaxone and nalidixic acid; and the bacterial resistance index shown that 39.70% were considered high level risk.Discussion: Household cats have a very important role in society, since the benefits they provide to their owners are clear, however, it is worth pointing out that these animals also pose risks to human health, caused by the transmission of zoonoses and also the possibility of transfer of antimicrobial resistance genes between bacteria of animal and human origin, as well as between bacteria of the normal microbiota and pathogenic microorganisms of diferents origins. Therefore, it is important to understand the health of these companion animal species, because they exhibit behavioral patterns that make them an important link in the epidemiological chain of potentially infectious microorganisms, which may show antimicrobial resistance. Extended spectrum beta-lactamase producer strains (ESBL) are resistant to penicillin, cephalosporin and monobactam, but they are susceptible to clavulanate. These enzymes hydrolyze the beta-lactam ring of the antibiotic structure, inactivating them. Nowadays bacterial resistance is considered to be one of the greatest problems in public health worldwide, as infections and diseases outbraks are caused by multiresistant bacteria are more and more frequent. The results of this study demonstrate the presence of strains of Enterobacteriaceae family associated to the high bacterial resistance, with samples that indicate ESBL producer strains in domiciled cats, in a city of west Parana state in Brazil. These results confirm that these cats can be considered as reservoirs of different microbial agents and resistance gens, being a health problem by the possibility of dissemination. The cat population is multiplying in a higher proportion compared to dogs and may probably became predominant in less than one decade. Due this situation and thinking about human, animal and environmental health new phenotypic studies to confirm the resistance gens and ESBL producers should be conducted in this specie.

Abstract
Background: The indiscriminate use of antibiotics both in humans and in animals, has contributed to the development of bacterial resistance. One of the key mechanisms in the resistance of enterobacteria to antibiotics is the production of extendedspectrum β-lactamases (ESBLs), which reduce the therapeutic options available. Several studies have been performed in different animal species in order to isolate and identify multidrug-resistant strains and determine their antibiotic sensitivity profile. The purpose of this study was to detect ESBL-producing enterobacteria in isolates from a pet blue-fronted amazon parrot.Case: A 16-year-old pet blue-fronted-amazon parrot (Amazona aestiva) weighing 0.445 kg, from the city of Presidente Castelo Branco, Paraná, Brazil, was admitted into a specialized veterinary clinic in the city of Maringá. This parrot was presented with agitation and aggressive behavior. It was fed with sunflower seeds, and its cage was small and unsanitary especially in the feeding and drinking areas, which were heavily contaminated with feces. The parrot had been diagnosed with acute sinusitis approximately one year prior, with a history of treatment with tylosin, thuya (a herbal remedy popularly used for fowl pox), and a mineral-vitamin complex. The clinical symptoms included dyspnea and bilateral increase of facial swelling, with a mass in the peri-nasal region. A membranous red tissue not related to the nictitating membrane was observed in the lower left eyelid. To obtain a better clinical evaluation, the bird was anesthetized with an intramuscular injection of dextroketamine 50 mg/kg (KetaminS+™). Subsequently, physical examination, head radiographic examinations, and an attempt at sinus draining were performed. The radiographic examinations showed a decreased amount of air in the nasal sinuses. For treatment, oral itraconazole and vitamin A were prescribed, and a dietary improvement, prioritizing the offering of fruits and industrialized food for parrots was proposed. Samples were collected from the cloaca and choanae by making rotating movements with compressed sterile swabs in the corresponding locations. All samples were kept in Amies transport media with activated coal and forwarded under refrigeration to the Laboratory of Preventive Veterinary Medicine and Public Health in the Post-Graduation Program in Animal Sciences with Emphasis in Bioactive Products at Universidade Paranaense (UNIPAR).Discussion: The samples were subjected to phenotypic antimicrobial sensitivity tests and phenotypic testing for detecting ESBL-producing strains. Escherichia coli was identified and isolated from the cloacal sample. Phenotypic tests for antimicrobial sensitivity, detected resistance to the following antimicrobials: ceftriaxone, ceftiofur, cefotaxime, cefepime, ampicillin, amoxicillin, amoxicillin + clavulanate, and tetracycline. The phenotypic test for detecting ESBL-producing strains was positive. The findings in this study had no relation with the clinical symptoms presented by the parrot. However, in the samples collected, it was possible to detect the presence of ESBL-producing Escherichia coli, indicating that this parrot had strains in its cloacal microbiota that were either multidrug-resistant or at a subclinical stage of an infection. This knowledge is important, since the presence of this bacteria in a pet represents an important factor in the dissemination of multidrug-resistant strains into the environment, as well as being a source of contamination for both humans and other animals.

Abstract
Toxoplasmosis is a zoonosis of worldwide distribution. Currently, two drugs, pyrimethamine and sulfadiazine, are used as a reference in the treatment of toxoplasmosis, but the resistance of Toxoplasma gondii appears as a relevant public health problem. In order to identify new drugs to toxoplasmosis treatment, we performed a molecular docking of raltitrexed to T. gondii thymidylate synthase-dihydrofolate reductase (TS-DHFR) and also evaluated its efficacy in infected mice. Initially, raltitrexed was docked on the crystallographic structures of TS-DHFR from T. gondii and Mus musculus. Then, 48 h after infection with the T. gondii RH strain, different groups of mice received an oral dose of raltitrexed (0.15, 0.75, and 1.5 mg kg-1). Two days after treatments, raltitrexed was able to prevent mortality and reduce the number of tachyzoites in the peritoneal fluid and liver imprints from infected mice. The results showed that raltitrexed has important protective activities against the T. gondii RH strain. Molecular docking still suggests that the effects against the parasite may be dependent on the inhibition of T. gondii thymidylate synthase. This study opens new perspectives for the use of raltitrexed in patients infected with T. gondii, especially when conventional treatments do not exhibit the expected efficacy.

Abstract
Resumo Capivaras são territoriais e vivem em grupos sociais, ocorrendo comumente em áreas antropizadas. Em algumas regiões do Brasil, estes animais apresentam infestação por carrapatos do gênero Amblyomma, que por sua vez são considerados como principal vetor biológico e reservatório natural da bactéria Rickettsia rickettsii, agente causador da Febre Maculosa Brasileira. Na UFSCar campus Araras, a interação entre capivaras, carrapatos e comunidade acadêmica é frequente, ocorrendo principalmente durante a estação seca. Este estudo teve como objetivo realizar um censo populacional das capivaras que ocupam o campus, identificando sua área de uso e se estes roedores se encontravam infestados por carrapatos. Realizou-se observação direta das capivaras, captura-marcação e recaptura com uso de um brete, e também coleta dos carrapatos nas capivaras e no ambiente. Registrou-se um total de 56 capivaras, com densidade de 1,50 ind./ha. Foram capturados 24 animais, sendo 25% machos e 75% fêmeas, dos quais 25% eram adultos, 45,8% jovens e 29,2% filhotes. A espécie de carrapato amplamente encontrada infestando tanto os animais como o ambiente foi A. sculptum. Conclui-se que o grupo de capivaras apresentou um número elevado de indivíduos por causa da abundância de recursos e ausência de predadores, e também com grande infestação por carrapatos.

Abstract
Abstract Toxoplasmosis is a worldwide zoonosis with important public health implications. The aims of this study were to determine and identify factors associated to the seroprevalence of anti-Toxoplasma gondii antibodies in humans and dogs from Jataizinho, Parana State, Brazil. Serum samples from 280 humans and 766 dogs, from rural and urban areas, were tested by indirect immunofluorescent antibody test. Positive dilutions were ≥ 1:16. Epidemiological informations were obtained through an individual questionnaire and data tabulation was performed using EpiInfo 3.5.3 (CDC, Atlanta). Statistical significance was evaluated by chi-square (ᵪ2) or Fisher's exact tests with a 5.0 % significance level. The seroprevalence in humans was 70.00% (196/280), as follows: 69.08% (143/207) in rural and 72.60% (53/73) in a slum urban community. The seroprevalence in dogs was 52.35% (401/766), as follows: 71.74% (99/138) in rural and 48.08% (302/628) in urban area. In rural areas, there was no factor associated to risk of infection. In urban slum community, visualizing more than four rats at home was a factor statistically associated to seropositivity for human toxoplamosis. Infection of urban dogs was associated to age, contact with stray dogs or rodents, and free access to street. The results indicated a similar possibility of contact with Toxoplasma gondii between dogs and humans living in rural or slum urban areas of small municipalities.

Abstract
The aim of this study was to investigate the presence of DNA of Borrelia burgdorferi sensu lato (s.l.) in ticks that feed on horses used for animal traction in rural Jataizinho, Parana, Brazil. Between February and June 2008, a total of 224 ticks was collected of which 75% were identified as Dermacentor nitens and 25% as Amblyomma cajenense. To amplify B. burgdorferi s.l. DNA, the intergenic space region (ISR) between the 5S (rrf) 23S (rrl) rRNA genes was used as targets for nested-PCR. Two ticks of the D. nitens species were positive for B. burgdorferi s.l. Both species showed a fragment of 184 bp, but the sequencing revealed 99.9% homology with the B. burgdorferi sensu stricto (s.s.) strain B31. These results showed, for the first time, the presence of spirochete DNA infecting ticks that parasitize horses used for animal traction, in the rural municipality mentioned. In conclusion, this study opens up promising prospects for determining the infection rate of B. burgdorferi s.s. genospecies or other species in the equine population, as well as the impact of the infection rate on Lyme disease in the state of Parana.

Abstract
BACKGROUND Leptospirosis, toxoplasmosis and brucellosis are diseases with worldwide distribution. Among stray dogs, these zoonoses are facilitated by direct contact with other animal species, by the habit of scavenging garbage and hunting in search of food, drinking standing water, smelling other animals' urine, licking female genitalia and the sexual act itself. The objective of this study was to detect antibodies anti-Toxoplasma gondii, anti-Leptospira spp., anti-Brucella canis and anti-Brucella abortus in stray dogs housed in shelters at Umuarama city, Paraná, Brazil. In order to detect toxoplasmosis, indirect immunofluorescence assay (IFA) was performed, agglutination microscopic (MAT) test for leptospirosis and agar gel immunodiffusion (AGID) and buffered acidified antigen (BAA) tests for brucellosis. RESULTS Of the 175 serum samples analyzed, 70.85% were considered positive for toxoplasmosis by IFA, 20% by MAT for leptospirosis and 2.85% by AGID for Brucella canis. CONCLUSIONS The serological results of this study showed that stray dogs housed at the private shelter are potential carriers of these three different zoonoses and contribute to the spread and maintenance of these etiologic agents in the urban area of Umuarama (PR), Brazil.

Abstract
The aim of the present study was to verify the association between seropositivity for IgG anti-Toxoplasma gondii antibodies and social, economic and environmental variables of pregnant women attending the public health centers of Paraná, Brazil. From January 2007 to July 2010, 2226 pregnant women were interviewed and detection of anti-T. gondii specific IgG and IgM antibodies was performed by chemiluminescence test. Seropositivity for anti-T. gondii IgG was observed in 1151 (51.7%) pregnant women, 29 of which (1.3%) presented IgM reagent with IgG of high avidity. The variables associated with the presence of IgG were residency in the rural area, more than one pregnancy, less than or equal to eight years schooling, low per capita income, age group, raw or poorly cooked meat ingestion, and contact with the soil. There was neither association with raw fruit and vegetable ingestion nor with the presence of cats in the residencies.

Abstract
The aim of this study was to conduct a serological survey for Lyme diseases, brucellosis, leptospirosis and toxoplasmosis and identify the risk variables related to these zoonoses in humans living in the rural area of Jataizinho, state of Parana, Brazil. A total of 63 rural properties were surveyed. Additionally, 207 serum samples collected from these rural area inhabitants were tested for indirect immunofluorescence (IFI) and western blots (WB) were performed to detect Borrelia burgdorferi (sensu lato); a tamponated acidified antigen test (AAT) and 2-mercaptoethanol (2-ME) were used to detect antibodies of Brucella abortus; the microscopic agglutination test (MAT) was carried out to detect antibodies anti-Leptospira spp. and IFI was used to find antibodies of Toxoplasma gondii. Two of the samples (0.96%) were reactive for Lyme borreliosis, three (1.4%) for brucellosis, 25 (12.1%) for leptospirosis and 143 (69.1%) for toxoplasmosis. Although the town of Jataizinho has a human development index (IDH) that was considered to be average (0.733) in the state of Parana, the low social, economic and cultural conditions of the population from small rural properties have resulted in lack of basic information on animal health and direct or indirect contact with the various species of domestic animals, wildlife and ticks have probably contributed to the prevalence levels found. These results show the need for additional regional studies in order to determine the epidemiological characteristics of these diseases as well as their respective vectors and reservoirs so that effective prophylaxis can be administered in the human population.

Abstract
The aim of this study was to evaluate associations between seropositivity for IgG and IgM anti-Toxoplasma gondii antibodies and socio-economic and environmental variables in pregnant women of Londrina, state of Paraná, Brazil. We interviewed 492 pregnant women, each of whom answered an epidemiological questionnaire, and collected blood samples for measurement of IgG and IgM anti-T. gondii antibodies by chemiluminescence. A confirmatory diagnosis of acute infection was made by an IgG avidity test. Titres of specific IgG anti-T. gondii were obtained by IFAT. Seropositivity for IgG anti-T. gondii antibodies was observed in 242 women (49.2%) and, of these, six pregnant women (1.2%) showed seropositivity for IgM. Age group, level of education, per capita income, presence of a cat in the house and a habit of eating green vegetables were all factors associated with a greater chance of infection with T. gondii. This study showed that 250 (50.8%) pregnant women were susceptible to T. gondii and considered to be at high risk for toxoplasmosis during pregnancy. Based on the results obtained, is critical to establish a program of health surveillance for toxoplasmosis, in order to contribute to diagnosis and early treatment during the prenatal period. It is also necessary to introduce measures to prevent the Toxoplasma infection in seronegative pregnant women.

Abstract
A total of 320 horses were studied in this paper, both male and female, between two and 17 years of age, which were used for traction of wagons in the urban area of the municipality of Londrina (PR). These animals were kept, after their daily work, in abandoned areas or plots, in the outskirts of the urban area of the city. When these animals were attended by the veterinarians, between 1996 and 2005, none of them presented symptoms suggesting leptospirosis. The most frequent reasons for the visit were loss of weight, unwillingness for work, parasitism, laminess, and wounds. Microscopic Seroagglutination Test (SAM), with 22 Leptospira serovars, was performed in sera sample from all these animals. The aim of this study was to investigate the occurrence of antibodies against Leptospira spp. in horses from the urban area of Londrina (PR). From the samples tested, 214 (66.88%) were considered positive, with titers between 100 and 3200, being that 49 (22.90%) presented antibodies against a single serovar of Leptospira, and 165 (77.10%) samples presented antibodies against two or more serovars simultaneously, where in 88 (53.33%) it was possible to characterize the most likely probable serovar. Antibodies against the serovar Icterohaemorrhagiae were detected in 32 (23.36%) animals.

Abstract
Toxoplasmosis possess worldwide geographic distribution and high serological prevalence in human beings and animals. Acquired way is, in the majority of the times, light or asymptomatic however, in approximately 15% of the cases can be developed the ocular form. The aim of this study is to research the occurrence of IgG anti-Toxoplasma gondii antibodies in children at an elementary school in Jataizinho (PR) and relate some factors with the epidemiology of the toxoplasmosis. A total of 276 samples of blood by using indirect immunofluorescence (IFA) where 128 (46.4%) were detected positives. The analysis of the variables indicated that the presence of domestic cats in the household was an important factor associated to the infection by T. gondii (OR= 3.45; 1.617.45) as well as to the children who described any kind of visual impairment (OR= 3.19; 1.11 - 9.35).

Abstract
Objetivou-se verificar a prevalência de anticorpos anti-Toxoplasma gondii em soros de caprinos de produção leiteira naturalmente infectados utilizando os testes de imunofluorescência indireta (IFI) e o de aglutinação modificada (MAT), determinar a especificidade e a sensibilidade do MAT e avaliar a concordância dos resultados entre os testes. Para o estudo foram coletadas 282 amostras de soro caprino, de propriedades do município de Pitanga, Paraná, região com uma grande pecuária de pequenos ruminantes. A prevalência encontrada pela IFI foi de 44,68% e 23,05% pelo MAT. Houve diferença estatisticamente significativa (p=0,0086) em relação ao sexo dos animais, sendo que as fêmeas foram mais soropositivas. Os resultados de sensibilidade e especificidade para o MAT foram, respectivamente, 42,2% e 94,9%. Na comparação dos resultados foi observada uma concordância moderada (Kappa = 0,42). A alta prevalência da infecção, aliada aos altos títulos obtidos pela IFI e aos sinais clínicos presentes nos rebanhos sugere a toxoplasmose como uma possível causa de problemas reprodutivos em caprinos. Os resultados de sensibilidade e especificidade para o MAT obtidos neste estudo permitem recomendá-lo como teste confirmatório para a espécie caprina.

Abstract
Toxoplasmosis is caused by an intracellular protozoan, Toxoplasma gondii, which has a wide geographical distribution. The main infection routes are ingestion of cysts from raw or badly-cooked meat, ingestion of oocysts from substrates contaminated with the feces of infected felines and congenital transmission by tachyzoites. The congenital form results in a severe systemic disease, because if the mother is infected for the first time during gestation, she can present a temporary parasitemia that will infect the fetus. Many of the clinical symptoms are seen in congenitally-infected children, from a mild disease to serious signs, such as mental retardation. Early diagnosis during the pregnancy is highly desirable, allowing prompt intervention in cases of infection, through treatment of pregnant women, reducing the probability of fetal infection and consequent substantial damage to the fetus. Conventional tests for establishment of a fetal diagnosis of toxoplasmosis include options from serology to PCR. Prevention of human toxoplasmosis is based on care to avoid infection, understanding the disease and serological exams during gestation. Pregnant women should be tested serologically from three months gestation, until one month after childbirth. Inclusion of serology for congenital toxoplasmosis along with the basic Guthrie test for PKU is of fundamental importance for early diagnosis of infection and so that treatment is initiated, in order to avoid possible sequels in the infant.

Abstract
Leptospirosis, brucellosis and toxoplasmosis are widely-distributed zoonosis, being the man an accidental participant of their epidemiological chains. The aim of this paper was to make a seroepidemiological report and identify occupational and environmental variables related to these illnesses in 150 workers in a slaughterhouse in the Northern region of Paraná. For the diagnosis of leptospirosis a microscopical seroagglutination test was applied; for brucellosis, the tamponated acidified antigen test and the 2-mercaptoetanol tests were used, and for toxoplasmosis the indirect immunofluorescence reaction test. For each employee an epidemiological survey was filled, which investigated occupational and environmental variables which could be associated with these infections. Positive results for leptospirosis were found in 4.00% of the samples, for brucellosis in 0.66% of samples and toxoplasmosis in 70.00%. From the three diseases researched, only the results for leptospirosis suggest occupational infection.
