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.
本研究的目的是确定由双腔吸虫病引起的肝脏组织病变的演变情况，作为寄生虫数量的函数。从屠宰场获取并对其进行肝片形吸虫感染尸检的274个牛肝脏中，191个显示出肝脏病变，表现为胆管增生、胆管改变和肝纤维化病变。胆管表面的改变和肝纤维化病变随着感染程度从0至300条肝片形吸虫而增加。超过这些数值，即301至600条吸虫时，则观察到有所下降。
