Histopathological study of chronic livers Fascioliasis of cattle in Sulaimani abattoir

[摘要] Liver fluke disease (fascioliasis) is an important parasitic disease may responsible for morbidity and mortality in most species of animals, like sheep, goat and cattle, as well as other domestic ruminants. The common causative agents are Fasciola hepatica and F. gigantica. The study aimed to detect the gross and microscopic lesions accompanied with chronic bovine liver Fascioliasis of local and Friesian cattle breeds in Sulaimani region and compared it with the same lesions in different species and breeds in other parts of the world according to the available literatures. During March to April 2013, fifty infected bovine livers of different ages were collected from Sulaimani abattoir, and examined grossly. Samples were taken from these livers parenchyma and bile ducts for histopathological examinations. The histopathological examinations illustration presence of different lesions in the liver parenchyma including, hepatocytes swelling, fatty changes, accumulation of bile pigment in bile canaliculi, congestion, neutrophils and eosinophils infiltration, abscess, telangiectasis, pericellular fibrosis, extensive fibrosis and liver cirrhosis. The lesions of bile duct ranged from infiltration of mononuclear inflammatory cells, portal fibrosis, bile duct hyperplasia, papillomatous projection, adenomatous hyperplasia and bile duct metaplasia. We concluded that Fascioliasis had pathological damage or destructive effect on bovine hepatobiliary system.
