  Clonorchis - Wikipedia, the free encyclopedia
Clonorchis sinensis, commonly known as the Human liver fluke or the Chinese liver fluke is a flatworm.
The egg of a Clonorchis sinensis (commonly: Human Liver Fluke), which contains the miracidium that develops into the adult form, floats in freshwater until it is eaten by a snail.
Dwelling in the bile ducts, Clonorchis induces an inflammatory reaction, epithelial hyperplasia and sometimes even adenocarcinoma of the bile ducts (cholangiocarcinoma), the incidence of which is high in fluke-infested areas.
