摘要

Background and Aim: Cystic echinococcosis, iEchinococcus granulosus/i, and liver flukes, such as iFasciola/i spp. and iDicrocoelium dendriticum/i, are important parasitic zoonoses, where they able to cause significant veterinary, medical, and economic problems. The present study was carried out to obtain the updated knowledge on the frequency of hydatidosis, fasciolosis, and dicrocoeliosis in the slaughtered sheep and cattle. Materials and Methods: Information were collected from meat inspection records using systematically visual inspection, palpation, and incision of the visceral organs in the industrial abattoir in Tehran, the capital of Iran, between February 1, 2015, and January 31, 2018. For an analysis of the data, SPSS version 16 was applied. Results: The hydatidosis infection in sheep and cattle was 2.48% and 2.25%, respectively. With respect to liver flukes, 0.62% and 0.25% sheep and cattle were infected by iFasciola/i spp., respectively; furthermore, 2.86% sheep and 0.79% cattle were positive for iD. dendriticum/i. Conclusion: The findings will provide considerable awareness for the future monitoring and control of these potentially important infections.
