Histological Effects of Cystic Echinococcosis on the Liver of Sheep

چکیده
Aim of the work: The author investigated the histological effects of hydatid cyst (echinococcosis) on the liver of sheep. Material and methods: This study was based on liver specimens of slaughtered sheep (twelve of infected and four of uninfected). Specimens were collected from abattoirs at Central Slaughterhouse area KSA. These specimens were investigated for the presence of hydatid cyst and then examined histologically for identification of the histopathological changes. Results: The infection with cystic echinococcosis induced significant elevation (P<0.05) in the hepatosomatic index of infected sheep. Hydatid cysts in the liver of sheep resulted in different histological lesions represented in inflammatory reaction, fibrosis and necrosis in the area near to the cysts. Meanwhile the hepatocytes exhibited vacuolated cytoplasm and dilated blood vessels and disintegration in the epithelia of the bile duct.
