[Histopathological analysis of bovine livers infested by Dicrocoelium dendriticum]

The object of this study was to determine the evolution of the lesions provoked by dicrocoeliasis in hepatic tissue, as a function of the quantity of parasites. Of the 274 bovine livers taken from the slaughterhouse and autopsied for Dicrocoelium dendriticum infection, 191 demonstrated hepatic lesions that revealed a proliferation of bile ducts, modifications of the bile ducts and hepatic fibrosis lesions. The modifications of the surfaces of the bile ducts and the hepatic fibrosis lesions increased with the level of infestation from 0 to 300 D dendriticum. Above these values, 301 to 600 flukes, a decrease was observed.
