Aim: Echinococcus and Taenia spp. are important but neglected zoonotic helminths of dogs. Dogs as the most relevant definitive hosts harbor several species of Taenia and Echinococcus simultaneously in their gastrointestinal lumen which are morphologically indistinguishable. In this study, we used a multiplex polymerase chain reaction (PCR) method to identify Taeniid infections which seem to be highly distributed in the study region.

Materials and Methods: A total of 450 dog fecal samples were collected from eight different areas of Zanjan province, northwest of Iran, and examined using a flotation method followed by multiplex PCR for detection and identification of parasites' eggs.

Results: Gastrointestinal parasites were found in 86 out of 450 fecal samples (19.1%) by microscopic examination. Taeniid eggs were observed in 5.6% of samples, containing 0.45%, 3.8%, and 1.3% Echinococcus granulosus, Taenia spp., and mix infection of both E. granulosus and Taenia spp., respectively. Echinococcus multilocularis was absent in the samples.

Conclusion: A relatively low rate of E. granulosus (1.8%) was observed in this study. However, risks of this parasite should not be overlooked, and control programs need to be extended for this species and other Taeniid spp. In particular, dogs are recommended to be dewormed more frequently.
