Abstract

A total of 77 Black Bengal goats (67 females and 10 males) of 3.5 to 5.0 years old between 18 and 20 kg live weights were used in this study. The whole liver with gall-bladder from respective carcass was collected at slaughter following fecal and postmortem examinations. Tissue sections of all lobes of each liver were prepared and stained with hematoxylin and eosin following a standard procedure. Results confirmed the presence of flukes surrounded by fibrous capsule in the liver. All the animals were suffering from chronic Fascilola gigantica infections. The blood vessels in most of the liver tissue were thickened due to proliferation of fibrous tissue around them. Focal infiltration of lymphocytes in the lobules, patches of focal accumulation of neutrophils and eosinophils were found in all the liver tissue. Proliferations of new bile ductules in the hepatic trinity around the bile ducts that were clogged by the flukes were also observed in most tissue sections.
