clonorchiasis clo·nor·chi·a·sis (klō'nôr-kī'ə-sĭs)
A disease caused by infestation with Clonorchis sinensis that affects the distal bile ducts after transmission by ingestion of raw, smoked, or undercooked fish.
chronic infection caused by Clonorchis sinensis, or liver fluke, a parasitic worm some 10 to 25 mm (0.4 to 1 inch) long that lives in the bile ducts of the liver in humans and other mammals. Clonorchiasis is a common disease in China, Vietnam, Korea, and Japan and is acquired by eating freshwater fish containing the fluke larvae. The fish are themselves infected by swallowing the larvae, which have earlier undergone a stage of their development in the liver glands of water snails.
