The aim of this study is to highlight the macroscopic and especially the microscopic tissular and organic lesions of the sheep bodies in order to establish the histopathological diagnosis of fasciolosis. The study was conducted in the period February 2015-April 2017. Nineteen sheep bodies were necropsied. The sheep were aged from 7 months to 3 years andwere from the breeds Turcana and Tigaie. Seven of the cases presented hepatic lesions at the necropsy exam expressed through diffuse hepatitis and interstitial fibrous hepatitis (pseudo-cirrhosis). At the necropsy exam, along with the hepatic lesions we highlighted the presence of Fasciola Hepatica in a very high number. The hepatic modification caused by Fasciola hepatica in the sheep taken into study are complex both in morphopathological shape and in extent being expressed through circulatory modifications, hypertrophy, dystrophy and lymphohistiocytic , eosinophilic and especially fibrous inflammation. The wide range of morphological modifications of the liver parenchyma, which appear in the pathological process end in liver fibrosis and pseudocirrhosis in sheep with repeated infestations. They always end up in death even though we apply repeated treatments with fasciolides. This is the reason why this disease is considered one of the most serious parasitic diseases for this animal species.
