Abstract

The main objective of this study was to determine the prevalence of taeniid parasites and the specific detection of Echinococcus granulosus using copro-DNA polymerase chain reaction (PCR) analysis in the stray dogs of Kerman, south-eastern Iran. From September 2013 to May 2014, faecal samples of stray dogs were collected from different parts of the city of Kerman and its suburbs. Faecal samples from dogs were collected randomly within 24 h of defecation. All samples were transferred to the research lab and coprological examinations were conducted by the formalin–ether concentration method. In the microscopically positive samples, mitochondrial cytochrome c oxidase subunit 1 (cox1) specific primers were used to determine the taeniid identity of the infection. In addition, another set of primers was used for the specific diagnosis of E. granulosus sensu lato. In total, 307 faecal samples from stray dogs were examined for the presence of the parasites. Taeniidae eggs were detected in 34 dogs (11.07%). All 34 taeniid-positive specimens were PCR positive for cox1 (444 bp). Of all taeniid-positive specimens, 21 samples (6.8% of all dog specimens) were positive according to primers specific for E. granulosus. The findings of the present study revealed that canine echinococcosis is prevalent in the stray dogs in Kerman. The findings of the present study have important implications for hydatid control programmes in the area.
