PATHOLOGICAL STATUS OF FASCIOLIASIS OF BOVINE LIVER COLLECTED FROM SLAUGHTER HOUSE OF DINAJPUR DISTRICT OF BANGLADESH

Abstract

The pathological status of fascioliasis in cattle of Dinajpur city of Bangladesh was carried out from January to June, 2020 by clinical signs, pathological and coprological examinations. A total of 75 cattle (27 male and 48 female) were recorded as study population for the present study. Seven cattle were found with pathological conditions There was engorgement of bile duct with fibrosis and the percentage of fibrosis of fascioliasis was 10.6%. While 17.3% roughened and thick capsule with whitish or reddish discoloration throughout the capsule. Gross lesions of fascioliasis found in the liver were increase in the size of the organ were 14.6%.. The infected bile ducts were also filled with blackish brown exudates giving the pipe stem appearance of the liver was noticed 13.3%. In histopathological study of acute Fascioliasis, there was lot of hepatocytic alterations like swelling of individual hepatocytes by increase in size and characterized by opaque cytoplasm. And sometime there was fatty change in which clear vacuoles appeared in the cytoplasm with peripherally located nuclei. Microscopically, depending on the duration and intensity of the infection, various changes were observed in the structures of Fasciola infected cattle liver. In conclusion Gross lesions of fascioliasis found in the liver were increase in the size of the organ and also there was engorgement of bile the duct with fibrosis. The infected bile ducts were also filled with blackish brown exudates giving the pipe stem appearance of the liver was noticed. In some cases, there was roughened and thick capsule with whitish or reddish discoloration throughout the capsule. My recommendation to study on pathological investigation to find out gross and microscopic lesions of the disease. To carry out further studies on isolation, morphology and characterization of Fasciola sp. To develop good management practices like hygienic condition, vaccination program to minimize the risk of the disease.
