| Abstract | ||
| The study was conducted to identification of liver lesions of sheep at Duhok abattoir from the month of May to October 2021. In the present study, 223 liver samples of sheep were examined and collected from Duhok Abattoir for pathomorphological studies. About 158 liver samples were severely infected with parasitic liver diseases, 140 it was cystic hydatidosis, 5 liver worm, and 13 samples was recorded as Hepatic cysticercoa, while the rest samples was abscesses, fatty degeneration, Congestion& hemorrhage. The prominent gross lesions in cystic hydatidosis included hard parenchyma with congestion and presence of fibrous tissue. While fascioliasis liver enlarged, icterus, fibrosis of bile ducts. As for hepatic abscesses, it was observed visually by presence of white to yellow solid texture compositions as spherical shapes to ovals and in different sizes and distributed through and the surface of the hepatic lobes and extended, As for congestion and hepatic hemorrhage, livers have been observed as congestion with enlarged of liver and coloration of the liver tissue while fatty change the lobes of livers were enlarged, pale yellow, soft and friable with rounded edges, Histopathological examination of liver cystic hydatidosis, revealed protoscoleces attached to the germinal layer of the cyst associated with extensive fibrosis of the liver parenchyma in cases of liver with presence of different larval stage of worms inside of the bile duct in cases of liver fluke,different larval stages were seen in the bile ducts accompanied by marked cellular reaction characterized by proliferation of fibroblasts, diffuse infiltration of mononuclear inflammatory cells, hemorrhage, abscesses with degeneration of hepatocyte. Biliary hyperplasia and fibrosis were also observed in the infected liver. | ||
