Background and Aim: Echinococcus granulosus is one of the smallest cestodes of the gastrointestinal tract of dogs and canids, with health and economic importance that humans and herbivorous are the intermediate hosts, and carnivorous are the definitive hosts of its. The present study was conducted to investigate the prevalence and genotype of E. granulosus in owned dogs.

Materials and Methods: In this descriptive cross-sectional study، 260 fecal samples of owned dogs in farms، industrial centers، animal husbandry and guard dogs of Shahrekord County were collected by recording demographic characteristics from 2018 to 2019 and were evaluated to determine the prevalence and genotypes of E. granulosus by parasitological methods (formalin-ether and zinc sulfate concentration methods) ،polymerase chain reaction and sequencing، then data were analyzed using SPSS 24 software.

Result: In this study، the rate of infection of dogs with Taenia species using formalin-ether and zinc sulfate concentrations were 17.7% (46/260) and 18.1% (47/260) respectively. Also، the prevalence of E. granulosus in owned dogs using PCR method was 5.4% (14/260). Sequencing studies of the results of the PCR indicated that dogs were infected with the G1 genotype or sheep strain. The statistical analysis of the data indicated that there was not significant relationship between the prevalence of echinococcosis and age، gender and habitat variables.

Conclusion: In this study, the infection of E. granulosus and G1genotype were detected in owned dogs in Shahrekord County. Therefore، contaminated dogs can be a potential danger to the owner of dogs and the herbivores of this region that recommended to design and implement control programs. Also, the infection of other hosts should be investigated in future studies.
