Modificările morfologice în fascioloza ovinelor
Abstract. The study was conducted between December 2017 and May 2019. Ten sheep bodies aged between 12 months and 5 years, from the Tsigai and Turcana breeds were subjected to necropsy examination. Seven of the sheep’s bodies presented at the necropsy exam showed liver injury, expressed by diffuse hepatitis and interstitial fibrous hepatitis (fibrosis, sclerosis, pseudocirrosis). At the necropsy examination, along with the hepatic lesions we highlighted the presence of F. hepatica in a very high number. The changes of the hepatic parenchyma are complex both from the morphopathological and histological point of view, as well from the standpoint of the extension surface, being expressed by circulatory changes, dystrophies, hypertrophies and inflammatory processes of eosinophilic or lymphohistiocitary type, with the development of severe fibrosis processes, especially in the case of repeated reinvasions. Repeatedly infested sheep, even when performing repeated antiparasitic treatments, end in death due to severe morphological changes in the liver. For these reasons, the fasciolosis is one of the most serious for this species of animals
