These keywords were added by machine and not by the authors. Similar to clonorchiasis, this parasitosis causes chronic bile duct inflammation, abnormal hyperregeneration of epithelia, and association with cholangiocarcinoma. Species of the trematode genus Opisthorchis cause the zoonotic parasitic disease, opisthorchiasis, mainly involving O. Infestation rate is high in certain regions of East Asia and is associated with increased risk for cholangiocarcinoma. Clonorchiasis denotes an infestation with the oriental liver fluke, Clonorchis sinensis. Rarely, fascioliasis results in the formation of huge and multilocular lesions, mimicking hydatid disease. Infestation of the human biliary tract by Fasciola results in a chronic, often severe and fibrosing cholangitis, sometimes ending up in hepatic inflammatory pseudotumor. Metacercariae released from snails are ingested by ruminants and humans who eat uncooked aquatic food such as watercress. Fasciola has a complex life cycle involving a distinct developmental stage in aquatic snails. Liver flukes are an important cause of ruminant disease in Europe, Africa, and Latin America. Fascioliasis is an infestation of the biliary tract by the common liver fluke, Fasciola hepatica, and by Fasciola gigantica. ![]() Tumor-like parasitic lesions and hepatobiliary cancers can be induced by several species of liver flukes.
