HISTOPATHOLOGICAL ANALYSIS OF THE BOVINE LIVERS AFTER INFECTION 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 qu antity of parasites. Of the 274 bovine livers taken from the slaughter house and autopsied for Dicrocoelium dendriticum infection, 191 demons trated hepatic lesions that revealed a proliferation of bile ducts, mo difications of the bile ducts and hepatic fibrosis lesions. The modifi cations of the surfaces of the bile ducts and the hepatic fibrosis les ions increased with the level of infestation from 0 to 300 D dendritic um. Above these values, from 301 to 600 flukes, a decrease was observe d.
