Pathological investigation of liver of the slaughtered buffaloes in Barisal district

Abstract

Livers (n = 80) of slaughtered adult buffaloes were examined for pathological changes during the period from July 2006 to March 2007 in two slaughterhouses of Barisal district. Livers exhibiting gross alterations were cleaned with normal neutral saline and the changes were recorded. The lesions containing tissue samples were collected in 10% buffered formalin for fixation. Grossly, Gigantocotyle explanatum infection (amphistomiasis) was found in 31.25% and Fasciola gigantica infection was in 22.5% cases. Hydatidosis (2.5%), abscesses (3.75%), and haemorrhages (2.5%) were found in the liver. Histopathologically, cirrhosis was found in 31.25% cases. Nodular hepatitis 7.5%, granulomatous hepatitis 5% and parasitic cholecystitis 15% were also recorded during the investigation. Survey showed that the severity of infection with G. explanatum 31.25% and F. gigantica 22.5% and cirrhosis 31.25% were of highest percentage.   Key words: Liver, amphistomiasis, hydatidosis, granulomatous, cholecystitis, cirrhosis, Fasciola gigantica DOI = 10.3329/bjvm.v5i1.1321 Bangl.
