Abstract
Cutaneous leishmaniasis is of particular importance in southern Iran. This study aimed to investigate the infection of rodents with Leishmania major in an urban area of Fars Province, located in southern Iran. Rodents were trapped and samples from the liver, spleen, and skin were collected. Impression smears were prepared from these tissues and any skin lesions and were examined microscopically. In addition, a portion of the samples were preserved for subsequent DNA extraction. A total of 41 rodents belonging to three species were caught from 10 trapping stations in gardens or houses within the area. The caught rodent species were Rattus rattus (n = 25, 60.97%), Mus musculus (n = 15, 36.58%), and Meriones persicus (n = 1, 2.5%). Leishmania amastigotes were seen in the spleen tissue smear of 6 (2.43%) of the rodents, including 4 of R. rattus and 2 of M. musculus. Skin lesions were observed on the muzzles of two R. rattus and one M. musculus. Samples taken from these lesions tested positive for Leishmania infection. Leishmania DNA was detected in 18 (43.9%) rodents, including 11 R. rattus, 6 M. musculus, and one M. persicus, based on DNA sequencing of the ITS2 gene and PCR of the kDNA. Phylogenetic reconstruction revealed that the parasite infecting the rodents was L. major. The detection of Leishmania infection in these rodents in urban areas raises concerns about the urbanization of cutaneous leishmaniasis caused by L. major. This urbanization poses unique challenges for control and prevention efforts.

Abstract
BACKGROUND Aedes aegypti, the primary vector of various human arboviral diseases, is a significant public health threat. Aedes aegypti was detected in Iran in 2018, in Hormozgan province, but comprehensive information regarding its genetic diversity and origin within the country remains scarce. This study aimed to determine the origin and genetic diversity of Ae. aegypti in southern Iran. METHODS Aedes aegypti mosquitoes were collected from Bandar Abbas City, Hormozgan Province, southern Iran, between May and July 2022. Specimens were morphologically identified. Origin and assess genetic diversity were assessed based on the mitochondrial DNA-encoded cytochrome c oxidase subunit I (mtDNA-COI) gene. RESULTS BLAST (basic local alignment search tool) analysis confirmed the accuracy of the morphological identification of all specimens as Ae. aegypti, with 100% similarity to GenBank sequences. Calculated variance and haplotype diversity were 0.502 and 0.00157, respectively. Among the 604 examined nucleotide sequences, only a single site was non-synonymous. Total nucleotide diversity and average pairwise nucleotides were determined as 0.00083 and 0.502, respectively. Fu and Li's D test values were not statistically significant. Strobeck's S statistic value was 0.487, and Tajima's D value was 1.53395; both were not statistically significant (P > 0.10). CONCLUSIONS Phylogenetic analysis revealed two distinct clades with minimal nucleotide differences and low haplotype diversity, suggesting the recent establishment of Ae. Aegypti in the southern region of Iran. The phylogenetic analysis also indicated an association between Ae. aegypti populations and mosquitoes from Saudi Arabia and Pakistan.

Abstract
Objectives Lucilia sericata (Diptera: Calliphoridae) is used in larval therapy for wound healing. Netrin-A is an enzyme secreted from the salivary glands of these larvae, and has a central role in neural regeneration and angiogenesis. This study aimed to produce the recombinant Netrin-A protein from Lucilia sericata larvae by the baculovirus expression vector system in the Sf9 insect cell line. Methods The coding sequence of Netrin-A was cloned, amplified in the pTG19 vector, and then cloned in the pFastBac HTA vector. It was then transformed into DH10Bac, and the recombinant Bacmid was subsequently transfected into Sf9 cells. The recombinant Netrin-A was purified by Ni-NTA agarose. The evaluation was done using SDS-PAGE and western blot, respectively. Finally, its concentration was calculated with the Bradford assay. Results The molecular weight of this protein was 52 kDa with 404 amino acids. The signal peptide was located between amino acids 24 and 25. The concentration of Netrin-A was calculated to be 48.8 μg/ml. It reaffirmed the characterized gene codes of Lucilia sericata Netrin-A in a previous study. Conclusions The generation of recombinant Netrin-A could be used in larval therapy, and as a biomarker in certain diseases. The netrin-A of Lucilia sericata was unprecedentedly cloned and expressed in a eukaryotic cell line. Given that this larva is FDA-approved, and non-pathogenic, it conduces to research on the development of maggot therapy in future.

Abstract
The application of integrative taxonomic approaches is useful to species delineation based on a combination of distinct types of characters, here morphological features and ribosomal DNA sequences. In this study, we surveyed ectoparasitic nematodes of the subfamily Merliniinae in cultivated and natural environments in Iran. Results of morphological and morphometrical studies, light and scanning electron microscopic observations, and molecular analyses allowed us the identification of fourteen known and one unknown species including representatives of the genera Amplimerlinius (five species), Geocenamus (one species), Merlinius (three species), Nagelus (two species), Paramerlinius (one species), Scutylenchus (two species), and Telomerlinius (one species). The unknown species, Scutylenchus sp., characterized by having 35-50 incisures at mid-body; lateral field with 6 longitudinal incisures; lip region slightly offset by a constriction, flattened at front end; bearing 5-7 annuli; cephalic framework not refractive; stylet robust, 18.3-27 μm long; post anal intestinal sac absent; tail elongate conical, dorsally convex, with 24 (19-28) annuli in ventral side, ending to a smooth terminus and males common; spicules 24.5-31 μm long. The phylogenetic analyses were carried out using molecular data from nuclear ribosomal DNA (rDNA) genes viz. D2-D3 expansion segments of the large ribosomal subunit (28S rRNA), partial small ribosomal subunit (18S rRNA), and internal transcribed spacer (ITS). The molecular variability of D2-D3 expansion segments of the 28S rRNA and partial 18S rRNA was low in this family in comparison to the ITS region, which could be a more helpful molecular marker in species and genus identification.

Abstract
Background Asymptomatic malaria is a major challenge to be addressed in the implementation of the malaria elimination program. The main goal of the malaria surveillance system in the elimination phase is to identify reliably all the positive cases of malaria reliably (symptomatic and asymptomatic) in the shortest possible time. This study focused on the monitoring of asymptomatic malaria reservoirs in areas where local transmission had been previously established. Methods It was a case-study approach that was conducted in the Anarestan area. A total of 246 residents and immigrants living in the area at the age range of 4-60 years old were randomly selected to be tested for malaria by microscope, RDT, and nested-PCR techniques. The inclusion criterion for participants to be entered into the study was the absence of specific symptoms of malaria. Moreover, participants who have been taking antimalarials for the last month were excluded from the study. Results The results indicated no positive cases of asymptomatic malaria among the participants tested by all methods. Conclusion The results of this study have shown that, without concerns for asymptomatic parasitic patients, a malaria elimination program has been successfully implemented within the studies area. In addition, the findings emphasized the existence of a strong malaria surveillance system in this area.

Abstract
Background: Phlebotomus and Sergentomya are distributed in the old-world regions and transmit leishmaniases through mammalian and reptile hosts. Cutaneous leishmaniasis (CL) is one of the most important diseases in Iran. Iranian sand flies belong to three Oriental, Palearctic, and Afrotropical Regions. Fars Province is located in Palearctic, but southern parts are affected Oriental region situations on phglebotomine population variety. Therefore, a comprehensive study was required on the vectors of the disease in this Province.
Methods: Regarding the approved role of the environmental factors in creating the fauna and distribution of living creatures, the “de martonne climate method” was used, and the climate was noticed as an important environmental factor for the determination of vector distribution. Accordingly, 14 sampling sites were selected from 10 foci in different climates of Fars Province. 19648 sand flies were collected from the studied areas in this Province during 2016.
Results: Phlebotomus papatasi and Se. antennata were the most frequent species, which were caught from in/outdoor areas. Phlebotomus sergenti and Ph. alexandri were caught from both Palearctic and Oriental zones but were more prevalent in the cold semi-arid climate of the Palearctic zone. Moreover, they were not caught from the hot desert and summer Mediterranean climates of the Oriental zone.
Conclusions: It seems that Ph. papatasi as the main vector of CL could be well distributed in different climates in Fars. Moreover, some species like Ph. sergenti preferred especial climates in the Palearctic zone. Therefore, these data could be helpful to control leishmaniases more efficiently.

Abstract
Leishmania parasites can cause zoonotic cutaneous leishmaniasis (CL) by circulating between humans, rodents, and sandflies in Iran. In this study, published data were collected from scientific sources such as Web of Science, Scopus, PubMed, Springer, ResearchGate, Wiley Online, Ovid, Ebsco, Cochrane Library, Google scholar, and SID. Keywords searched in the articles, theses, and abstracts from 1983 to 2021 were cutaneous leishmaniasis, epidemiology, reservoir, vector, climatic factors, identification, and Iran. This review revealed that CL was prevalent in the west of Iran, while the center and south of Iran were also involved in recent years. The lack of facilities in suburban regions was an aggravating factor in the human community. Some parts of southern Iran were prominent foci of CL due the presence of potential rodent hosts in these regions. Rhombomys opimus, Meriones lybicus, and Tatera indica were well-documented species for hosting the Leishmania species in Iran. Moreover, R. opimus has been found with a coinfection of Leishmania major and L. turanica from the northeast and center of Iran. Mashhad, Kerman, Yazd, and sometimes Shiraz and Tehran foci were distinct areas for L. tropica. Molecular identifications using genomic diagnosis of kDNA and ITS1 fragments of the parasite indicated that there is heterogeneity in leishmaniasis in different parts of the country. Although cutaneous leishmaniasis has been a predicament for the health system, it is relatively under control in Iran.

Abstract
Venomous arthropods such as scorpions and bees form one of the important groups with an essential role in medical entomology. Their venom possesses a mixture of diverse compounds, such as peptides, some of which have toxic effects, and enzymatic peptide Phospholipase A2 (PLA2) with a pharmacological potential in the treatment of a wide range of diseases. Bee and scorpion venom PLA2 group III has been used in immunotherapy, the treatment of neurodegenerative and inflammatory diseases. They were assessed for antinociceptive, wound healing, anti-cancer, anti-viral, anti-bacterial, anti-parasitic, and anti-angiogenesis effects. PLA2 has been identified in different species of scorpions and bees. The anti-leishmania, anti-bacterial, anti-viral, and anti-malarial activities of scorpion PLA2 still need further investigation. Many pieces of research have been stopped in the laboratory stage, and several studies need vast investigation in the clinical phase to show the pharmacological potential of PLA2. In this review, the medical significance of PLA2 from the venom of two arthropods, namely bees and scorpions, is discussed.

Abstract
Hormozgan Province is one of the important foci of malaria in Iran. In addition to malaria pathogens, mosquitoes also transmit the pathogens that cause dirofilariasis and West Nile fever in the province. Also, the threat of emerging aedine-borne viruses that cause infections, such as Chikungunya, dengue, and Zika, is noticeable. There is little information about the fauna and bionomics of Culicinae in the province. The present investigation aimed to study the fauna, diversity, and bionomics of culicines. The study was conducted from September 2016 to April 2017 in four counties of Bandar Abbas, Bandar Khamir, Bashagard, and Jask. In total, 3,236 larvae and 1,901 adults including 16 culicine species were collected. The larvae of Culiseta longiareolata (Macquart) (25.65%), Culex pipiens Linnaeus (16.62%), and Cx. quinquefasciatus Say (16.16%) were most abundant and Cx. hortensis Ficalbi (0.09%) was least abundant. Among adults, Cx. laticinctus Edwards (33.19%), Cx. quinquefasciatus (31.09%), and Cx. pipiens (11.99%) were the most prevalent species and Cs. longiareolata (0.47%), Aedes caballus (Theobald) (0.90%), and Cx. bitaeniorhynchus Giles (0.90%) were the least prevalent species. The pairwise similarities of fauna of the counties and different collecting methods and diversity indices were investigated. More ecological data, especially on host preference, seasonality, and larval habitat characteristics, are needed as a basic knowledge for any intervention measures using integrated vector management.

Abstract
Ae. aegypti is an important vector for transmission of some dangerous arboviral diseases, including Dengue Fever. The present study was conducted (from August 2017 to January 2020) to survey the fauna of Culicine mosquitoes, emphasizing the existence of this invasive species in oriental parts of the country located near the Persian Gulf. Different sampling methods were used to collect all life stages of the mosquito. After morphological identification, a molecular study based on Cytochrome Oxidase (COI) gene-specific primers was performed. Then, the COI gene was sequenced via the Sanger method. A total of 4843 adults and 11,873 larvae were collected (8 species of Culex, one species of Culiseta, and 5 species of Aedes). Fifty-five Ae. aegypti specimens (8 adults and 47 larvae) were identified.Based on the biology and ecological requirements of Ae. aegypti, the possibility of the permanent establishment of this species in the tropical climate of the region is very likely. Considering the detection of this invasive vector mosquito species in Iran and the high incidence of some arboviral diseases in the neighboring countries, and continuous movements of the settlers of these areas, potential outbreaks of arboviral diseases can be predicted. Planning and implementing an immediate surveillance and control program of the vector mosquito is vital to prevent the permanent establishment of this invasive vector mosquito species in southern Iran.

Abstract
Head lice (Pediculus humanus capitis) are one of the most common insects causing infestations in humans worldwide, and infestation is associated with adverse socio-economic and public health effects. The development of genetic insensitivity (e.g., target site insensitivity = knockdown resistance or kdr) to topical insecticides has impaired effective treatment. Therefore, this study was undertaken to review and meta-analyze the frequency of pyrethroid resistance in treated head louse populations from the beginning of 2000 to the end of June 2021 worldwide. In order to accomplish this, all English language articles published over this period were extracted and reviewed. Statistical analyses of data were performed using fixed and random effect model tests in meta-analysis, Cochrane, meta-regression and I2 index. A total of 24 articles from an initial sample size of 5033 were accepted into this systematic review. The mean frequency of pyrethroid resistance was estimated to be 76.9%. In collected resistant lice, 64.4% were homozygote and 30.3% were heterozygote resistant. Globally, four countries (Australia, England, Israel, and Turkey) have 100% kdr gene frequencies, likely resulting in the ineffectiveness of pyrethrin- and pyrethroid-based pediculicides. The highest resistance recorded in these studies was against permethrin. This study shows that pyrethroid resistance is found at relatively high frequencies in many countries. As a result, treatment with current insecticides may not be effective and is likely the cause of increased levels of infestations. It is recommended that resistance status be evaluated prior to insecticide treatment, to increase efficacy.

Abstract
Cutaneous leishmaniasis (CL) is caused by intracellular obligate parasites (Leishmania spp.) carried by the blood-sucking of female sandflies and transmitted between mammalian hosts. Despite the high incidence and prevalence of Leishmania cases in many countries, it has been a neglected tropical disease. The current treatment approaches are limited by the complications such as loss of fertility and drug resistance. It is, therefore, essential to find new medicines to treat leishmaniasis. CRISPR/Cas9 as a powerful genome-editing tool provides the opportunity to create precise genetic manipulation to investigate the molecular basis of different leishmaniasis cases. Therefore, our main goal was to evaluate the CRISPR PX-LmGP63 vector effect on pathogenicity of Leishmania majorin vitroto challenge for using CRISPR/Cas9 as a therapeutic CL through the reduction of L. major pathogenicity by manipulating the GP63 gene. In this study, L. major parasites were transfected with CRISPR/Cas9 vectors constructed by electroporation and then added to macrophage cells on RPMI. The effect of CRISPR/Cas9 constructs on GP63 mutation, viability, and status of L. major was investigated by counting phagocytic parasites into macrophages and DNA sequence analysis. Our data validate that the use of CRISPR/Cas9 in L. major creates a new stop codon and disrupts the frame sheet of the gene by creating a new insertion (thymine), which prevents its expression. In addition, the parasite count was significantly different in the case and control of infected macrophages (P < 0.05). This study shows the successfully targeted manipulation of the L. major GP63 gene via the adaptation of the CRISPR/Cas9 editing tool. The manipulation of GP63 revealed a reduction in the infection load compared to wild-type parasite infection. Therefore, more studies are necessary for this field to help achieve a new method for the prevention and treatment of CL disease.

Abstract
Natural selection and sexual selection are cardinal factors in shaping the body of animals such as scorpions. Scorpio maurus (Scorpiones: Scorpionidae) has a worldwide distribution. Sexual dimorphism has been reported from this species in a study in Egypt. Morphometry is used to determine the sexual dimorphism between the two sexes. In the current study, scorpions were collected from six locations of the southern and northern provinces of Fars, Iran. In this study, 53 morphological characters of 15 specimens of each sex of Scorpio maurus were studied based on statistical analyses; however, dimorphism was only observed in 21 morphological characters, including chelicerae and carapace length, pedipalp characters, width of the second segment of metasoma, telson and pectin length, number of left pectin teeth, and some of the leg's segments. It means that these characters are in the control of sexual and natural selection. This study was performed for the first time on Scorpio maurus species in Iran.

Abstract
A new guaianolide sesquiterpene lactone with cytotoxic properties was isolated from Euphorbia microsphaera Boiss. To determine the highest active fraction and isolate bioactive compounds, a bioassay guided fractionation approach was used. The general toxicity properties of the plant's extracts and fractions (fr1-10) were assessed against Artemia salina, Oryzeaphilus mercator, and Tribolium castaneum. Cytotoxic activities were investigated against normal human foreskin fibroblasts and two malignant cell lines, including human breast cancer (MCF-7) and human fibrosarcoma cells (HT1080) using the MTT assay at different time points of 24, 48, and 72 h. Single crystal X-ray diffraction (SC-XRD) and mass spectrometry data were used to determine the structure of the active guaianolide sesquiterpene lactone (3aR,4S,4aS,5R,7aS,9aS)-5-hydroxy-5,8-dimethyl-3-methylene-2-oxo-2,3,3a,4,4a,5,6,7,7a, 9a decahydroazuleno [6,5-b] furan-4-yl acetate (named aryanin). Chloroformic fraction 7 (fr7, LC50 = 93.50 μg/mL for general toxicity) had the highest toxicity result, with a mortality rate of more than 50% for both insect species after 12 h at 15 mg/mL. The highest cytotoxicity of aryanin was observed on 24 h treated MCF-7 with an IC50 of 13.81 μg/mL. After 24 h, the inhibition of MCF-7 cell proliferation was 92%-94% at concentrations of 25-50 μg/mL, respectively. On MCF-7, the IC50 was found to be 49.35 μg/mL after 72 h. This compound had a considerable cytotoxicity (IC50 ≤ 12.5 μg/mL, 24 h) on human foreskin fibroblasts. In contrast to the MCF-7 cell line, the proliferation of human foreskin fibroblasts was increased after 72 h.

Abstract
Color assessment remains a challenging aspect of esthetic dentistry. This study aimed to evaluate inter-operator agreement and accuracy in assessing shade parameters and to investigate the effect of different clinical backgrounds of the operators under different lighting conditions. Three veneers with a single shade (VITA VM7, shade 2M2: VITA Zahnfabrik, Bad Säckingen) and different shade characteristics (lustre, translucency and opacity) were assessed by 24 operators with different backgrounds using natural and color-corrected light (Trueshade, Interempresas Media, S.L.U. - Grupo Nova Àgora, Spain). Shade assessment accuracy was only 5.5% using natural light and 9.7% using Trueshade. The majority of operators identified value and hue correctly, although chroma was mostly identified incorrectly. The most accurate assessments were recorded by technicians, and translucency was the characteristic to be least accurately recorded. Inter-operator agreement of shade was better with Trueshade compared without Trueshade, although group agreements of shade characteristics were higher without Trueshade for lustre and opacity, but not for translucency. Operators showed limited agreement and poor accuracy in assessing shade and shade characteristics and the clinical background had an effect on shade selection. Technicians were more reliable in shade assessment. Trueshade could be a promising tool to improve shade assessment outcomes.

Abstract
Objectives:
Since there have not been any studies on the roles of the Iranian mosquitoes in the transmission of Rickettsia spp. and Coxiella burneti, the present study investigates the roles of mosquitoes in the transmission of the pathogens using the PCR techniques for the first time in Iran.
Methods:
The present study was conducted in Fars province during the activity seasons of mosquitoes in 2017-18. The primer design was done to investigate the probability of mosquito’s contamination with Rickettsia spp. and Coxiella burnetii. The conventional PCR was used after the extraction of DNA from mosquitoes to study the contamination.
Results:
A total of 1103 adult mosquitoes were collected and identified. Among them, 3 genera and 11 species were identified, including Anopheles (25.74%), Culex (51.84%) and Culiseta (22.39%) genera. All tested mosquitoes were negative in terms of contamination to Rickettsia spp. and Coxiella burnetii.
Conclusion:
Based on the results, mosquitoes are not considered as vectors of Rickettsia spp. and Coxiella burnetii in this part of the country currently. Further studies on a larger scale are needed to examine the exact role of mosquitoes (as a possible vector with high abundance and mobility) in the transmission of these pathogens in tropical areas of Iran.

Analysis of the effect of methadone and temperature on the development rate of Calliphora vicina (Diptera: Calliphoridae): A forensically important fly. Nusantara Bioscience 12: 87-91. The development rate/time of flies is a scientific method to estimate the minimum time elapsed after death. Several studies have shown that opioids and temperature affect maggot growth rates. However, there are few published data that investigate the effect of ante-mortem methadone use on larval length of Calliphora vicina (Robineau-Desvoidy). Therefore, the purpose of this research was to investigate the effect of methadone and temperature on the development rate/time of this species. During this study, four rabbits were administered 0.10, 0.50, 1.0, and 10 mg/kg of methadone via gavage over a period of 14 days, and a five rabbit, which did not receive methadone, was used as a control. The rabbits' tissues were separated and exposed to maggots for rearing. Minimum developmental times of C. vicina life stages at six constant temperature regimes were provided. From hours 48 to 96, larvae feeding on tissues containing 10 mg/kg methadone developed more rapidly than those feeding on tissues containing 0.1, 0.50, and 1 mg/kg and also from the control. In the present study, development rate of C. vicina was linearly related to temperature (R2 = 0.96, p =0.02) between 16 and 32°C. The results revealed that the differences observed in the rates of development were sufficient to alter postmortem interval estimates based on larval development by up to 24 h.

Abstract
Background: West Nile Virus, a mosquito-borne flavivirus, causes a variety of symptoms in human, from asymptomatic infection to neuroinvasive disease. Several studies have been conducted on the seroprevalence of WNV infection in different areas from Iran. This study was performed to find the presence of antiviral antibodies in human serum among some high risk population and awareness of health care staff about symptom of the WNV infection. Methods: Study performed in five geographical districts based on high population of immigrant and domestic birds and prevalence of the antiviral antibodies in horses which was reported previously. Totally 150 human blood samples were collected during 2018. The samples collected from patients referred to the clinics. The ELISA method used to detect IgG and IgM antibody against WNV. Logistic regression models used to analyze the effect of sex, age, keeping birds and urban/rural residence on the risk of infection. The awareness of health care staff about symptom of infection surveyed. Results: From all blood donors, 41 samples (27.33%) showed positive to IgG antibody. From which 56.10% were males and remaining females. None of the mentioned factors had a significant relationship. Health care staff had less attention to the infection. Conclusion: Although the prevalence of antibodies was relatively high, due to the similarity to other viral diseases, health care staff had less attention to the disease. The study showed that people in these areas have been exposed to the virus. Further research activities are recommended for control of this arbovirus.

Abstract
Background Allergenic arthropods are crucial agents in inducing medically important respiratory diseases like asthma and the inflammation of the respiratory tract worldwide. Aims This study was conducted to determine the prevalence of all arthropods in the dwellings of people referred to the asthma and allergy clinic in Shiraz. Methods This was was a cross-sectional descriptive study. Participants were 100 allergic patients who had tested positive (roach- and mite-sensitive). Mites were collected from their houses using a vacuum cleaner; other arthropods were caught with sticky traps. Direct observation and flotation methods were used and the samples were stored in 70% ethanol. Morphological characteristics were identified using valid taxonomic keys. Results Overall, 624 specimens were identified belonging to 14 orders (4 orders of mites: Astigmata, Cryptostigmata, Prostigmata and Mesostigmata; and 10 other arthropod orders: Diptera, Coleoptera, Hymenoptera, Thysanura, Thysanoptera, Entomobryomorpha, Blattodea, Siphonaptera, Pscoptera and Isopoda). The 2 most numerous species collected were Musca domestica and Dermanyssus gallinae. Conclusion A small number of dwellings were infested with cockroaches; none were infested with the common house dust mites. The allergies induced in these patients could likely be attributed to other arthropods that are not considered main allergens in asthma and allergy clinics in the Islamic Republic of Iran. Health surveillance and prevention of infestation for these arthropods could have an immense impact on the control of the allergenic arthropod community, prevention of respiratory diseases, and personal health in Shiraz.

Abstract
BACKGROUND & OBJECTIVES Leishmania major and L. tropica are the main pathogens of cutaneous leishmaniasis (CL) in several rural and some urban regions of Iran, respectively. The aim of this study was to detect Leishmania species, and update the distribution data of these species in humans suspected to CL in two endemic foci in southern Iran. METHODS From March 2016 to March 2017, 276 positive samples from of 350 suspected cases were diagnosed and compared by different diagnostic methods, viz. microscopy, culture, and PCR. In PCR assay, four different gene identifications were performed including minicircle kDNA, and cysteine protease B genes for Leishmania detection, and glyceraldehyde-3-phosphate dehydrogenase, and internal transcribed spacer 1 genes for Crithidia detection. RESULTS In total, 68% (235/350) and 65.3% (177/271) of patients suspected of leishmaniasis were positive by microscopy and cultivation methods. In PCR assay, L. major, and L. tropica were detected in 86.2% (238/276), and 13.1% (36/276) of CL cases, respectively. Also, dermal L. infantum strain was isolated from 0.7% (2/276) of post-kala-azar dermal leishmaniasis patients. In addition, Crithidia fasciculata was detected in two CL patients chronically infected with L. major. INTERPRETATION & CONCLUSION It appears that the epidemiology of CL has changed during the last decades and can complicate the control strategy aspects of CL in southern Iran. Therefore, more epidemiological, ecological, and gene polymorphism studies are needed to understand the pathogenic role of these species in human, as a main host of leishmaniasis in Iran.

Abstract
Background Head lice infestation (Pediculosis) is one of the most important health challenges particularly in primary school-aged children. It is often present among 6–11-year-old students in various tropical and temperate regions of the world. The aim of this study was to examine epidemiologic indices and comparative analysis of two pyrethroid-based and one non-chemical pediculicide products on head lice treatment of primary school girls in a rural setting of Fars province, south Iran, as part of a randomized controlled assessor blind trial. Methods Before treatment, infested students were screened using plastic detection combs to find live head lice. Three independent parallel groups, each with about 25 participants (#77) were eventually twice with a week apart treated with either 1% permethrin, 0.2% parasidose (d-phenothrin) or 4% dimeticone lotion preparations. In each case, a questionnaire form was completed on epidemiologic factors. Data were registered after a fortnight from primary scalp treatment and re-inspection on days 2, 6, 9 and 14. Data analyses were performed using Chi-square test with a P-value < 0.05 being taken as statistically significant. Results From 3728 inspected students, 87 (2.33%) girls were infested with head lice, Pediculus humanus capitis De Geer, 1778. Ten students dropped out pertaining to exclusion criteria. No significant correlation was found between head lice infestation level and hair length, hair style, itching, nationality, age, settlement site and baths; but there was a significant relationship between age and hair style (P = 0.027). The efficacy values on each of the above re-inspection days from each of the three treatments were 81, 74, 70 and 63% for permethrin; 83, 92, 100 and 100% for dimeticone; and 96, 88, 96 and 92% for d-phenothrin; respectively. A quartile difference in efficacy of permethrin relative to dimeticone on day 14 represented the scale of head lice resistance to permethrin treatment. There were significant statistical differences in case re-inspection days 9 (P = 0.008) and 14 (P = 0.003) post treatment. Only two dropout cases, one non-compliant and the other lost before the second-week treatment, from permethrin trial were observed following two applications a week apart. Conclusions Dimeticone lotion had the fullest efficacy (100%) among all treatments. This high cure rate was attributed to the low level of infestation and the extent of patients’ involvement. Parasidose swiftly ameliorated the infested cases by the second day since initial treatment. Female third grade students were the most infested cohort.

Abstract
Larval therapy with Lucilia sericata is a promising strategy in wound healing. Axon guidance molecules play vital roles during the development of the nervous system and also regulate the capacity of neuronal restoration in wound healing. Netrin-1, one of the proteins that larvae secrete, plays a useful role in cell migration and nerve tissue regeneration. The UNC-5 receptor combines with a netrin-1 signal and transmits the signal from one side of the membrane to the other side, initiating a change in cell activity. In the current study, we identified the full length of the UNC-5 receptor mRNA in L. sericata using different sets of primers, including exon junction and specific region primers. The coding sequence (CDS) of the UNC-5 receptor was sequenced and identified to include 633 base-pair nucleic acids, and BLAST analysis on its nucleotide sequence revealed 96% identity with the Lucilia cuprina netrin-1 UNC-5 receptor. The protein residue included 210 amino acids (aa) and coded for a protein with 24 kD weight. This gene lacked the signal peptide. Furthermore, the UPA domain is conserved in UNC-5. It lied at the interval of 26–131 aa. We identified the CDS of netrin-1UNC-5 receptor in L. sericata. It could be applied to research activities implementing a new essential component design in wound healing.

Abstract
Amblyomma hebraeum (Koch, 1844), has been already reported from along the coast of South Africa, eastern Swaziland, southern Mozambique, eastern Botswana, and in southern and eastern regions of Zimbabwe. The aim of this study was to determine the ecto-parasites and the harmful arthropods of wildlife animals, collected from cages of Shiraz zoo in Fars province, southern Iran, in 2016. Accordingly, the Ticks collected from the white camels were identified as Amblyomma hebraeum. This species which was collected from white camel of Fars province, is reported for the first time from Iran. The presence of A. hebraeum poses a serious threat to the livestock industry in Iran and there is need to investigate the presence of this species in Iranian livestock.

Abstract
West Nile virus (WNV) and Zika virus (ZIKV) are mosquito-borne viral infections. Over the past few decades, WNV has been associated with several outbreaks involving high numbers of neuroinvasive diseases among humans. The recent re-emergence of ZIKV has been associated with congenital malformation and also with Guillain–Barre syndrome in adults. The geographic range of arthropod-borne viruses has been rapidly increasing in recent years. The objectives of this study were to determine the presence of IgG specific antibodies and the genome of WNV and ZIKV in human samples, as well as WNV and ZIKV genomes in wild-caught mosquitoes in urban and rural areas of the Hormozgan province, in southern Iran. A total of 494 serum samples were tested for the presence of WNV and ZIKV IgG antibodies using ELISA assays. One hundred and two (20.6%) samples were reactive for WNV IgG antibodies. All serum samples were negative for ZIKV IgG antibodies. Using the multivariable logistic analysis, age (45+ vs. 1–25; OR = 3.4, 95% C.I.: 1.8–6.3), occupation (mostly outdoor vs. mostly indoor; OR = 2.4, 95% C.I.: 1.1–5.2), and skin type(type I/II vs. type III/IV and type V/VI; OR = 4.3, 95% C.I.: 1.7–10.8 and OR = 2.7, 95% C.I.: 1.3–5.5 respectively, skin types based on Fitzpatrick scale) showed significant association with WNV seroreactivity. We collected 2,015 mosquitoes in 136 pools belonging to 5 genera and 14 species. Three pools of Culex pipiens complex were positive for WNV RNA using real-time reverse transcription polymerase chain reaction (rtRT-PCR). ZIKV RNA was not detected in any of the pools. All WNV ELISA reactive serum samples were negative for WNV RNA. In conclusion, we provided evidence of the establishment of WNV in southern Iran and no proof of ZIKV in serum samples or in mosquito vectors. The establishment of an organized arbovirus surveillance system and active case finding strategies seems to be necessary. In recent decades mosquito-borne viruses have reached and adapted to new habitats, and now they can be found in nearly all continents. Facilitated goods transportation, live stock exchange, people travelling more easily, and most importantly world climate alterations, might be some of the reasons for this mosquito habitat spreading. Emergence of WNV in North America, Europe, and most Mediterranean countries like Turkey, Greece and Israel is evidence of this spreading. Furthermore, emergence and re-emergence of some of these mosquito borne viruses in new areas may be accompanied with changes in their pre-known pathogenesis. Re-emergence of ZIKV in the South Pacific and America from 2007 to 2016 was accompanied with an increase in neurovirulent diseases and congenital malformations. In this study, we evaluated the presence of WNV and ZIKV via serological and genome detection in human samples and mosquitoes (viral genome analysis) from southern Iran. This region is on the coast with a warm and tropical climate suitable for inhabitation and expansion of the vectors harboring these two viruses. We caught a large spectrum of mosquitoes from these areas. After classification, we analyzed the mosquitoes’ pools for WNV and ZIKV genomic RNA. Our results showed that 20.6% of the studied human samples were IgG reactive to WNV while no antibodies against ZIKV were detected. We found WNV RNA genome in three mosquitoes’ pools. The genomic analysis was negative for ZIKV in both human and mosquito samples. Based on the results WNV is notably circulating in southern Iran; while no evidence of ZIKV infection in people or circulation in any of the vectors was observed.

Abstract
Zoonotic cutaneous leishmaniosis (ZCL) is a crucial public health challenge in Iran. Sandflies feed on reservoir rodents' blood infected with Leishmania parasite and transmit it to other hosts. This study was conducted to find out the composition and monthly activity of sandflies as well as to identify the protozoan pathogens (Leishmania/Crithidia) by polymerase chain reaction (PCR) in an emerging ZCL focus of Abarkooh, Yazd province, Iran, in 2016. A cross-sectional study was done in rural areas of Abarkooh. From April to November 2016, sticky traps were used indoor and outdoor to capture sandflies once every fortnight. Their composition and monthly activity were recorded. Following identification of sandflies and DNA extraction from them, PCR was used to identify their parasite and match it against samples taken from ZCL confirmed and suspected patients' lesions. After collection, a total of 2045 sandflies (779 indoor, 1266 outdoor) were identified to species level. Sandfly activity started early April in this area with two active peaks (one late May and the other late August) terminated about mid-November. Seven Phlebotomus species and three Sergentomyia species were identified. The most and the least abundant species were P. papatasi (40.1%) and P. alexandri (0.09%), respectively. Using PCR, only 6% (12:200) of P. papatasi sandflies were infected with Leishmania parasite. No Crithidia was detected in either sandflies or human lesions (176 specimen). Based on the highest abundance both indoor and outdoor of P. papatasi, this sandfly was considered the main vector of ZCL in this area. The capture of P. caucasicus, P. mongolensis, and P. ansarii from rodent burrows showed these species were likely involved in pathogen transmission in reservoir rodents' burrows.

Abstract
Cutaneous Leishmaniasis (CL) is one of the main neglected vector-borne diseases in the Middle East, including Iran. This study aimed to map the spatial distribution and species composition of sand flies in Hormozgan Province and to predict the best ecological niches for main CL vectors in this area. A database that included all earlier studies on sand flies in Hormozgan Province was established. Sand flies were also collected from some localities across the province. Prediction maps for main vectors were developed using MaxEnt model. A total of 27 sand fly species were reported from the study area. Phlebotomus papatasi Scopoli, Phlebotomus sergenti s.l. Parrot, Phlebotomus alexandri Sinton, Sergentomyia sintoni Pringle, Sergentomyia clydei Sinton, Sergentomyia tiberiadis Adler, and Sergentomyia baghdadis Adler (Diptera: Psychodidae) had the widest distribution range. The probability of their presence as the main vectors of CL was calculated to be 0.0003-0.9410 and 0.0031-0.8880 for P. papatasi and P. sergenti s.l., respectively. The best ecological niches for P. papatasi were found in the central south, southeast, and a narrow area in southwest, whereas central south to northern area had better niches for P. sergenti s.l. The endemic areas are in Bandar-e Jask, where transmission occurs, whereas in Bastak, the cases were imported from endemic foci of Fars province. In conclusion, proven and suspected vectors of CL and VL were recorded in this study. Due to the existence of endemic foci of CL, and favorite ecological niches for its vectors, there is potential risk of emerging CL in new areas.

Abstract
BACKGROUND The visceral leishmaniasis parasite, Leishmania infantum, is naturally transmitted through the bites of phlebotomine sand flies. Alternative routes of transmission are questioned. The main aim is to verify the passage of L. infantum kDNA in ticks, Rhipicephalus sanguineus, blood feeding on a parasitemic dog in Shiraz, south of Iran. METHODS A total of 180 Leishmania-free ticks collected from fields and bred on lab rodents, were divided into eight groups and allowed to feed on a dog (Canis familiaris) for fixed periods of time. These and all third generation stages of ticks were checked for L. infantum kDNA using conventional PCR protocol. RESULTS The infection rate was significantly higher in female than male ticks (p=0.043). The rates were higher among nymphs (25/60; 42%) than adult ticks (37/120; 30.8%). The kDNA of L. infantum was not detected in ticks 24 h post-feeding. It was, however, positive among the second to fourth groups of nymphs (4/10; 40%, 10/20; 50% and 11/20; 55%) and adult (12/30; 40%, 14/30; 46.6% and 11/30; 36.6%) ticks. Eggs and unfed larvae recovered from the third and fourth adult groups (2 weeks, 4 weeks) were 100% PCR-positive. The data revealed the passage of L. infantum kDNA in nymphs and adults of brown dog tick following fixed time intervals post blood feeding on an infected dog. CONCLUSIONS The natural transovarial and transstadial passage of kDNA through ticks was shown by PCR.

Abstract
Despite control programs, which aim to eliminate malaria from Iran by 2025, transmission of malaria has not been removed from the country. This study aimed to monitor malaria from asymptomatic parasitaemia and clinical cases from about one year of active case surveillance and potential vectors of malaria in the newly emerged focus of Mamasani and Rostam, southern Iran during 2014-2015. Samples were collected and their DNAs were extracted for Polymerase Chain Reaction (PCR) assay using specific primers for detection of Plasmodium species. The Annual Parasite Incidence rate (API) was three cases per 1,000 population from 2,000 individuals in three villages. Parasites species were detected in 9 out of the 4,000 blood smear samples among which, 6 cases were indigenous and had no history of travels to endemic areas of malaria. Also, the prevalence rate of asymptomatic parasites was about 0.3%. Overall, 1073 Anopheles spp. were caught from 9 villages. Totally, 512 female samples were checked by PCR, which indicated that none of them was infected with Plasmodium. Despite new malaria local transmission in humans in Mamasani and Rostam districts, no infection with Plasmodium was observed in Anopheles species. Because of neighboring of the studied area to the re-emerged focus in Fars province (Kazerun) and important endemic foci of malaria in other southern provinces, such as Hormozgan and Kerman, monitoring of the vectors and reservoir hosts of Plasmodium species would be unavoidable. Application of molecular methods, such as PCR, can simplify access to the highest level of accuracy in malaria researches.

Abstract
Some nematologists recently placed the genus Pratylenchoides, ("Lesion Nematode-like") in the family Merliniidae. To investigate Pratylenchoides species diversity and their relationships with other Merliniidae genera, specimens were collected from various habitats in the northern and northwestern provinces of Iran. The morphological and molecular study yielded three species of the genus Pratylenchoides, including P. persicus n. sp. This new species is characterized by having lip region rounded or slightly flattened anteriorly with four or five fine but distinct annuli, pharyngeal glands off-set or slightly overlapping the intestine dorsally, all three gland nuclei located anterior to the pharyngo-intestinal valve and tail cylindrical with truncate to low rounded terminus. Morphologically, P. persicus n. sp. can be distinguished from the most closely related species, P. heathi by having shorter body and stylet length in females and males, as well as a shorter tail with different terminus in females. Pratylenchoides laticauda and P. cf. nevadensis are reported from Iran for the first time. Phylogenetic analysis based on the D2/D3 region of the large subunit of ribosomal DNA revealed Pratylenchoides as a monophyletic genus, and it supports the delineation of the new species, P. persicus n. sp.

Abstract
BACKGROUND Cutaneous leishmaniasis is a major health problem in Iran in spite of implementation of control program. This infectious disease caused morbidity in less than 27000 people in 2010. This study was set to determine some ecological aspects of sand flies in Fasa district, Fars Province, southern Iran during 2011-2012. METHODS A total of 4792 sand flies were captured by means of sticky paper and CDC miniature light traps in 10 selected villages from the beginning to the end of the active season, from which 1115 specimens were captured for abundance study and 3677 specimens captured for monitoring monthly activities in Fasa. After species identification, extracted DNA was processed for detection of Leishmania parasite infection in sand flies. RESULTS Twelve species (6 Phlebotomus, 6 Sergentomyia) were identified. The most common sand fly was P. papatasi (82.4%) which represented 86.6% of sand flies from indoors and 82.7% from outdoors. The monthly activity of the species extended from April to the end of November. There were two peaks in the density curve of this species, one in June and the second in September. Natural infection to L. major was detected in P. papatasi (25 out of 130 sand flies, 19.2%). CONCLUSION Phlebotomus papatasi is considered as a main vector of zoonotic cutaneous leishmaniasis in Fasa, Fars Province, south of Iran.

Abstract
Zoonotic Cutaneous Leishmaniosis (ZCL) remains the most crucial vector-borne public health disease particularly in endemic rural parts of Iran. The main aim of this study is to identify wild sand flies (Diptera: Psychodidae), determine their infection rate, and differentiate their host blood meal sources using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Sand fly populations were caught with sticky paper traps from 10 different villages in the county of Darab, Fars province, southern Iran. Following their species identification, they were used in one step PCR to determine their infection with Leishmania spp. parasites. They were then subjected to PCR-RFLP protocol to identify and differentiate their blood meal sources. Two genera of Phlebotomus and Sergentomyia comprising 13 species of sand flies were identified in this region. From a total of 150 parous female sand flies, encompassing 4 different medically important species, 7 specimens (4.7%) including 6 Phlebotomus papatasi and 1 Phlebotomus bergeroti were infected with Leishmania major. Molecular data indicated that about 32% of female sand flies fed on man, while nearly 43% fed on rodent and canine hosts. Molecular detection is an efficient way of differentiating the source of blood meals in female sand flies feeding on different vertebrate hosts. It is suggested that P. papatasi is not highly anthropophagic and appears to be an opportunistic feeder on man. This species is, however, the primary vector of ZCL in this region.

Abstract
Herbal extracts were used to investigate the in vivo efficacy of <em>Artemisia absinthium</em> on the treatment of cutaneous leishmaniasis in susceptible mice. A total of 40 BALB/c mice were subjected to assays. In each, 3-5×10<sup>3</sup> amastigotes of standard <em>Leishmania major</em> strain were inoculated subcutaneously into the tail base of mice. Groups of mice were assigned as: I-negative control, II-positive control, III-Glucantime®, IV-ointment twice a day, V-ointment with oral medicine, VI-oral medicine on parasite injection, VII-oral medicine once ulcer develops, and VIII-ointment-based crème on ulcer. The gold standard of clinical infection control was based on ulcer size measurement using a Vernier scale weekly during 4 weeks Post-Ulcer Development (PUD). The mean ulcer sizes in different groups were compared using the post hoc Dunnett's 3 statistical analyses. There was a significant difference between the two groups of ointment with medicine (V) and medicine on parasite inoculation (VI) (P ≤ 0.027). Antiulcer activity and healing was noted after oral treatment with aqueous extract on parasite injection. There was a significant difference between data from positive control group and local ointment with oral medicine (P ≤ 0.045) indicating that ointment use facilitated ulcer growth. There was also a significant difference between data from Glucantime® use and ointment with medicine group (P ≤ 0.039) which showed the deteriorating effect of oil-based ointment use. The oral administration of extract had an effect similar to Glucantime® use and led to the repair of ulcer. <em>A. absinthium</em> extract as oral feeder appeared to cause modulation of host responses, ulcer size reduction and tissue repair.<p> </p>

Abstract
The genus Pratylenchoides has recently been transferred from the family Pratylenchidae to Merliniidae. To investigate further the relationship between these ‘Pratylenchus-like’ species (residing in the subfamily Pratylenchoidinae) and the subfamily Merliniinae, more than 500 soil samples were collected from various natural and agronomic habitats in the northern and north-western provinces of Iran. In this study, paratypes or populations of 22 species of Pratylenchoides, including the Iranian populations of P. alkani, P. crenicauda, P. erzurumensis, P. laticauda, P. nevadensis, P. ritteri and an undescribed species, were studied. Intra- and interspecies variation of the following characters were investigated: position of the pharyngeal gland nuclei, shape of female and male head, striation of female tail terminus, number of lateral lines at mid-body and in phasmid region for females, presence of intestinal fasciculi, and shape of sperm. Combining morphological and molecular data prompted us to propose two clusters of related Pratylenchoides species. One cluster includes P. crenicauda, P. variabilis and P. erzurumensis, whereas the second cluster consists of P. alkani, P. nevadensis and P. ritteri. Our data point to a sister positioning of P. magnicauda vis-à-vis all Pratylenchoides species included in this research. Analyses of SSU rDNA (for family and subfamily relationships) and partial LSU rDNA sequences (for intrageneric relationships) data revealed: i) the distal and nested positioning of all Pratylenchoidinae within the Merliniidae; ii) the single transition from ectoparasitism to migratory endoparasitism within the family Merliniidae corresponds with the current subfamily partitioning; and iii) support for the monophyletic nature of the genus Pratylenchoides.

Abstract
Crimean-Congo haemorrhagic fever (CCHF) is a potentially fatal systemic viral disease in many parts of the world, including Iran. The nationwide incidence of human CCHF in endemic areas was 870 confirmed cases with 126 deaths (case fatality rate, CFR = 17.6 %) in the decade leading to 2012. The detection of the CCHF virus (CCHFV) genome in tick vectors is of fundamental importance for identifying these ticks as potential reservoirs of CCHFV infection. From May to October 2013, following detection of four new clinical cases resulting in two deaths in the city of Mashhad (northeast Iran), hard ticks were recovered from infested livestock in 40 villages in Khorasan-Razavi province and examined by the microscopic method for species identification. About a quarter of the ticks were then subjected to reverse-transcription polymerase chain reaction (RT-PCR) to detect the CCHFV genome. The PCR products were then sequenced, and their phylogenetic lineages were determined. A total of 407 hard ticks were captured, representing seven different species in two distinct genera. Members of the genus Hyalomma were widely distributed in all but two of the villages studied, and this was also the most frequent (83.3 %) tick genus. Of 105 adult ticks subjected to RT-PCR, four (3.8 %) ticks were found positive for the CCHFV genome. One brown ear tick, Rhipicephalus appendiculatus, was found to be naturally infected for the first time anywhere in the world. Ticks of Hyalomma asiaticum, Hyalomma marginatum, and Rhipicephalus turanicus were also found to be naturally infected with CCHFV. CCHFV found in these four different tick species were clustered in the same lineage with the Matin and SR3 strains from Pakistan and some other strains from Iran, indicating that these tick species were naturally infected with genetically closely related CCHFV in the region. The presence of CCHFV infection in four different hard tick species was confirmed using RT-PCR in northeast Iran. Part of this infection was attributed to Rh. appendiculatus, which is thus a potential new natural vector of CCHFV in Iran. It is also confirmed by phylogenetic analysis that CCHFV in this region is genetically closely related, even in the different tick species.
