| Abstract | ||
| The present study deals with histopathologcally of sheep liver infected with hydatid cysts caused by from Echinococcus granulosus The pieces of liver were fixed soon after they taken out from the animal’s body and sections prepared and stained with haematoxylin and eosin,(HE), then were examined microscopically. The cysts were differ in size and intensity of histopathological changes proportional inversely with the size of cyst. The pathological changes appeared clearly in regions close to the cyst wall and the microscopic examination showed that the hepatocytes were deformed in size and shape due to reduced cytoplasmic contents and many gaps were seen around the fibrous cyst wall,also showed nuclear pykonosis and elongated cells in some area of tissue.These effects were seen at the distance from the cysts wall. also there were some fibrotic tissue near the cyst wall with some areas of calcifications. The present study indicated that the hydatid cyst fluid produced high toxic effect in tissue surrounding the cysts caused by both histopathologically and mechanically changes. | ||
