Farjani Kish GH, Mootabi Alavi A., Prevalence of typical and atypical hydatidosis in sheep and goats, Onl J Vet Res., 26 26 (12): 949-959, 2022. We report prevalence, macroscopic and microscopic lesions of typical and atypical hydatidosis in livers and kidneys of 3450 sheep and 1350 goats slaughtered in Shiraz abattoir, Iran. We found prevalence of 5.4% in sheep and 3.4% goat in livers but only 1 cyst in kidney of sheep. We detected 1-5 cysts in 203 livers, 5-10 in 22 and >10 only in 9. We found 8 sheep and 1 goat atypical cases and 74 fertile and 144 sterile cysts. Macroscopically we observed severe damage of hepatic parenchyma and hardening proliferation of fibrous tissue. In atypical cases, by microscopy, hepatic lesions were characterized by conglomerate of vesicles and cysts, granulomatous hepatitis, severe necrosis surrounded by mononuclear inflammatory cells and cirrhosis.
