Hydatid cyst is one of the parasitic zoonoses caused by infection with the larval stage of Echinococcus granulosus tapeworm. The spread of this parasite is global and is of great importance in terms of public health. To date, ten different species of this parasite have been identified that differ in characteristics such as life cycle, epidemiology and pathogenesis. The purpose of this study was to determine the genotype and phylogenetic relationship of hydatid cysts isolated from livestock of Bushehr province, Iran. About 62 samples of hepatic and pulmonary hydatid cysts were collected from slaughtered animals. DNA extracted by phenol-chloroform method was amplified by PCR using primers specific for the cox1 gene. The PCR products of 50 samples were sequenced and analyzed using BioEdit software and compared with sequences in the GenBank. The phylogenetic tree was drawn using Neighbor Joining tree-NJ method, and its reliability was evaluated. Sequencing results showed that out of 50 sequenced samples, 43 samples had the genotype of Echinococcus granulosus and 7 samples had the genotype of Taenia hydatigena. By drawing a phylogenetic tree, all 43 hydatid cyst samples belonged to G1 strain. The predominance of G1 strain of hydatid cyst in livestock of Bushehr province shows the main role of this genotype in establishing the life cycle of parasite in this region and if the genotype of the parasite in dogs and humans is determined, then these findings can be used to disrupt the life cycle of the parasite and reduce the human infections.Cutaneous leishmaniasis (CL) is a zoonotic disease with 1 to 1.5 million annual incidences. Microscopic examination of the Giemsa stained slides is the most common diagnostic method for CL. However, this method cannot distinguish leishmania species. Hence the present study was conducted to identify leishmania species by high-resolution melting (HRM) analysis in the newly emerged foci of CL in Sabzevar, northeast of Iran. In this cross-sectional study, fifty patients with suspicious cutaneous lesions referring to the designated health center for diagnosis and treatment of CL in Sabzevar during 2017-2018, were recruited. All collected samples and prepared slides were stained for microscopic examination and then undergone HRM real-time PCR (HRM-PCR) assay to identify species of Leishmania parasites. The results of HRM-PCR technique showed that Leishmania major (L. major) was the dominant causative parasite in the newly emerged foci whereas L. tropica (L. tropica) was positive only in two patients. This was the first time that 7SL RNA-HRM-PCR assay was performed to precisely identify leishmania parasites in the northeast of Iran. We proved the newfound foci in which both L. major and L. tropica were present. In contrast to the recent studies which identified only L. major in the region, we showed that L. tropica was still present.Mites infestation and gastrointestinal parasites including coccidia are common problems reported in pets, petting farms and farmed practices. Sarcoptes sp. and Cheyletiella sp. could be a potential zoonosis from rabbits to human. Detection of mites and coccidia with their zoonotic potential in meat-farmed rabbits from three (3) commercial farms in Selangor were investigated. Tape impression, fur pluck, skin scraping and ear swab tests were used for mites detection and faecal samples was used for coccidia examination by using McMaster's technique and the identification of Eimeria spp. was further analysed by sporulation technique. The overall prevalence of mites and Eimeria spp. (oocysts) in rabbits were 51.85% ± 0.38 (standard deviation; S.D.) and 76.47% ± 0.42 respectively. Sarcoptes scabiei was the most frequent mite found (25.92% ± 0.44), followed by Cheyletiella parasitovorax and Psoroptes cuniculi. Nine Eimeria spp. were identified and the oocysts of E. perforans shows the highest prevalence (64.71% ± 3.97) followed by E. exigua, E. coecicola, E. magna, E. flavescens, E. irresidua, E. intestinalis, E. media and E. stiedai. There was a significant difference (p = 0.013) where large-scale farm has a higher prevalence of coccidia than small scale farms apparently due to the excessive stocking density as coccidia are easily transmitted among rabbits through ingestion of sporulated oocysts. In conclusion, mites and coccidia are commonly present in the commercial rabbit farms, thus control and preventive measures should be executed to reduce the incidence of parasites. The zoonotic mites Sarcoptes scabiei and Cheyletiella parasitovorax detected in this study could be regarded as a public health concern especially when handling the rabbit.This study evaluated in vitro effect of different concentrations of Aloe vera (A. BI-3802 datasheet vera) ethanol extract and honey against Acanthamoeba spp. cysts in comparison with chlorhexidine (the drug of choice for treatment of Acanthamoeba infection) at different incubation periods. Four different concentrations of the tested agents were used, 100, 200, 400, and 600 μg/ml for A. vera ethanol extract and 25, 50, 100, and 200 μg/ml for honey. Isolated Acanthamoeba spp. cysts from keratitis patients were incubated with different concentrations of the tested agents as well as chlorhexidine 0.02% (drug control) for different incubation periods (24, 48, 72 h). After each incubation period, the effect of A. vera extract and honey against Acanthamoeba cysts was assessed by counting the number of viable cysts, determining the inhibitory percentage and detecting the morphological alternations of treated cysts compared to non-treated and drug controls. Both A. vera ethanol extract and honey showed a concentration and time-dependenr than that of chlorhexidine (76.9%). Using a scanning electron microscope, Acanthamoeba cysts treated by A. vera ethanol extract showed alternations in their shapes with flattening, collapsing, and laceration of their walls. Also, treated cysts by honey were highly distorted and difficult to identify because most of them were shrinkage and collapsed to a tiny size. On the other hand, chlorhexidine showed less structural and morphological changes of Acanthamoeba cysts. A. vera ethanol extract and honey had considerable cysticidal effects on Acanthamoeba cysts. They may give promising results for treatment of Acanthamoeba keratitis.
