No abstract availableOf 27 calves given 1, 000 Fasciola gigantica metacercariae, 22 became infected. The animals were slaughtered between one and 31 weeks after infection and the livers were examined for gross lesions, flukes were counted and measured, and a histological examination was made. It was found that necrosis, inflammation and thrombosis, which were the first lesions to appear, were caused by migrating flukes, and that cirrhosis developed as the flukes entered the bile ducts. Finally, the walls of bile ducts containing flukes became calcified. D.A.Cz.
