Abstract
AIMS The purpose was to characterize Salmonella Heidelberg (SH) and Minnesota (SM) isolates in terms of their resistance and persistence profile and to assess the antimicrobial effect of benzoic acid (BA) and polypyrrole (PPy). METHODS AND RESULTS The 20 isolates from broiler litter drag swabs were submitted to antibiogram and efflux pump expression. The minimum inhibitory/bactericidal concentration (MIC/MBC) of the compounds, synergistic activity, time kill, biofilm production, presence of related genes, and molecular docking between compounds and bacterial target sites were evaluated. All isolates showed multidrug resistance (MDR) and BA and PPy showed mean MIC (1750 and 342 µg ml-1) and MBC (3167 and 1000 µg ml-1), respectively. None of the isolates expressed an efflux pump. The compounds showed synergism against an SH isolate and reduced the count by 3 logs in the presence of the compounds after 4 h. Most isolates (16/20) produced weak to moderate biofilm and 17 showed genes related to biofilm. The compounds interacted with two essential proteins, 3,4-dihydroxy-2-butanone 4-phosphate synthase proteins and ferritin-like domain-containing protein, in bacterial metabolism at different target sites. CONCLUSIONS It can be concluded that BA and PPy showed activity on SH and SM, MDR, and biofilm producers, with a potential synergistic effect.

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
AIMS Develop a species-specific multiplex PCR to correctly identify Edwardsiella species in routine diagnostic for fish bacterial diseases. METHODS AND RESULTS The genomes of 62 Edwardsiella spp. isolates available from the National Center for Biotechnology Information (NCBI) database were subjected to taxonomic and pan-genomic analyses to identify unique regions that could be exploited by species-specific PCR. The designed primers were tested against isolated Edwardsiella spp. strains, revealing errors in commercial biochemical tests for bacterial classification regarding Edwardsiella species. CONCLUSION Some of the genomes of Edwardsiella spp. in the NCBI platform were incorrectly classified, which can lead to errors in some research. A functional mPCR was developed to differentiate between phenotypically and genetically ambiguous Edwardsiella, with which, we detected the presence of Edwardsiella anguillarum affecting fish in Brazil. SIGNIFICANCE AND IMPACT OF THE STUDY This study shows that the misclassification of Edwardsiella spp in Brazil concealed the presence of E. anguillarum in South America. Also, this review of the taxonomic classification of the Edwardsiella genus is a contribution to the field to help researchers with their sequencing and identification of genomes, showing some misclassifications in online databases that must be corrected, as well as developing an easy assay to characterize Edwardsiella species in an end-point mPCR.

Abstract
Research background Despite the great properties of bacterial cellulose, its manufacture is still limited due to difficulties in large-scale production. These problems are mainly related to low production yields and high overall costs of the conventional culture media normally used. To surpass these problems, it is necessary to identify new cheap and sustainable carbon sources. Thus, this work aims to isolate and select a high cellulose-producing Komagataeibacter strain from vinegar industry, and study its potential for bacterial cellulose synthesis in an industrial soybean co-product, known as soybean molasses, used as fermentation medium. Experimental approach One isolated strain was able to produce high amount of cellulose in the standard Hestrin-Schramm medium, so we tested its ability to produce this biopolymer in a soybean molasses medium. The characteristics and properties of the produced bacterial cellulose membranes were analyzed by thermogravimetric analysis, X-ray diffraction, infrared spectroscopy, water-holding capacity and rehydration ratio. Genetic analysis of the selected strain served to determine its genus and species. Results and conclusions An isolated strain that produced the highest amount of cellulose in Hestrin-Schramm medium (3.7 g/L) was genetically identified as Komagataeibacter intermedius V-05. This strain produced 10.0 g/L of cellulose in soybean molasses medium. Membranes from both substrates had similar chemical structure, crystallinity and thermal degradation. Soybean molasses proved to be a suitable alternative medium for biosynthesis of cellulose in comparison with the standard medium. In addition to providing higher production yield, the membranes showed great structural characteristics, similar to those obtained from standard medium. Novelty and scientific contribution In this research, we have isolated and identified a Komagataeibacter strain which exhibits a high capacity for cellulose production in soybean molasses. The isolation and selection of strains with high capacity for microbial metabolite production is important for decreasing bioprocess costs. Furthermore, as there is a necessity today to find cheaper carbon sources to obtain microbial products at a lower cost, soybean molasses represents an interesting alternative medium to produce bacterial cellulose for its industrial application.

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
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
Streptococcus agalactiae is an invasive multi-host pathogen that causes invasive diseases mainly in newborns, elderly, and individuals with underlying health complications. In fish, S. agalactiae causes streptococcosis, which is characterized by septicemia and neurological signs, and leads to great economic losses to the fish farming industry worldwide. These bacteria can be classified into different serotypes based on capsular antigens, and into different sequence types (ST) based on multilocus sequence typing (MLST). In 2015, serotype III ST283 was identified to be associated with a foodborne invasive disease in non-pregnant immunocompetent humans in Singapore, and the infection was related to raw fish consumption. In addition, a serotype III strain isolated from tilapia in Brazil has been reported to be resistant to five antibiotic classes. This specific serotype can serve as a reservoir of resistance genes and pose a serious threat to public health. Thus, new approaches for the control and treatment of S. agalactiae infections are needed. In the present study, 24 S. agalactiae serotype III complete genomes, isolated from human and fish hosts, were compared. The core genome was identified, and, using bioinformatics tools and subtractive criteria, five proteins were identified as potential drug targets. Furthermore, 5,008 drug-like natural compounds were virtually screened against the identified targets. The ligands with the best binding properties are suggested for further in vitro and in vivo analysis.

This work evaluated the effects of dietary supplementation of A-Live (phytogenic) either individually or in combination with Aquaform (potassium diformate, acidifier) on juvenile Nile tilapia (Oreochromis niloticus) growth performance, innate immune parameters, gut microbiome, and resistance against Francisella noatunensis subsp. orientalis challenge. Each experimental group contained 140 fishes (34.3 ± 0.33) in two 150L tanks. The experimental design consisted of five groups: a negative control; treated groups (G1, G2, G3) supplemented with different concentrations of A-Live and Aquaform in the feed; and a positive control (PC) for pathogen infection. Groups G1, G2, G3, and PC were challenged with Francisella spp. after 15 days. After infection, the mortality was significantly lower in groups G1, G2, and G3 (p < 0.01). Furthermore, these groups showed significant increase (p < 0.05) in daily weight gain, feed conversion rate, and specific growth rate. The PC group presented increase (p < 0.05) in the leukocytes and neutrophils number. Innate immunity parameters showed no difference between treatments after infection. Microbiome analysis revealed an increased number of bacteria belonging to the Vibrionaceae family after pathogen infection suggesting a secondary pathogen function of these bacteria. These results validate the beneficial effects of these products in tilapia farming.

Abstract
Background: Leptospirosis and brucellosis are zoonosis worldwide distributed that have great economic importance, especially in goats. This study aimed to carry out a cross-sectional study to determine the prevalence of anti-Leptospira spp. and anti-Brucella abortus antibodies and to determine epidemiological variables associated to infection by these ethiological agents in goats.Materials, Methods & Results: Serum samples were collected from 1055 goats of 95 properties distributed in 18 regional centers of Paraná State from April to August of 2010. Collected samples were submitted to microscopic agglutination test (MAT) for the detection of anti-Leptospira spp. antibodies with 22 reference serovars: Australis, Bratislava, Autumnalis, Butembo, Castellonis, Bataviae, Canicola, Fortbragg, Whitcombi, Cynopteri, Grippotyphosa, Hebdomadis, Copenhageni, Icterohaemorrhagiae, Panama, Pomona, Pyrogenes, Hardjo, Wolffi, Shermani, Tarassovi and Londrina 1 (L1). The samples were also submitted to buffered acidified plate antigen test (BAPA) and 2-mercaptoethanol test (2-ME) to detect anti-Brucella abortus antibodies. The results obtained from epidemiological and serological study were analysed by Epi Info 3.5.3. We observed 9.9% (104/1055) of goats reagents in at least one serovar of Leptospira spp. and no reagent animal to Brucella abortus. The variables that were statistically significant with leptospirosis were: production type meat, sewer destination in dry sump, frequent abortion, shared use of pastures, slaughter of animals on the property, the presence of pigs and wild animals such as deer and capybaras on the property.Discussion: This was the first study about antibodies prevalence against Leptospira spp. and Brucella abortus in goat herds from Paraná State. The presence of both animal species were statiscally associated to risk of leptospirosis. It is necessary avoid the acess of these animals in herds, decreasing the dissemination of the agent. The production type meat is a form of creation in which the animals have no care of zookeepers and continuous veterinary care. The final destination of sewage was statistically associated to risk of leptospirosis in goats and this is a big problem in rural properties, requiring greater attention of authorities for proper disposal of this wastewater, reducing water and food contamination. Among the variables related to management, the herds that used rented pasture or shared pastures also were statistically associated to risk of leptospirosis in goats; with the sharing of pastures a greater flow of animals transiting in the pickets occurs, allowing not only flocks of goats, but other species also, to use the same pastures and become more exposed to certain diseases. The slaughter of pigs, sheep, cattle and goats on the property is a problem for animal and human health due to lack of sanitary inspection. Abortion is one of the main clinical signs of leptospirosis in farm animals, particularly goats. The knowledge of these results will be useful to develop control programs for the disease in Paraná State herds. The absence of circulating anti-Brucella abortus antibodies in goat herds has also been reported in other Brazilian States.
