Clonorchis sinensis
Clonorchis sinensis was named after that the worm was discovered in the bile duct of a Chinese carpenter in Calcutta, a harbor city of India, in 1874. our archaeologists found this worm in a body from a tomb dating from the second century B.C. in Jiangling,Hubei Province. The Chinese liver fluke is distributed in Asia (Far East region). The infections result from eating raw or half-cooked fresh water fish and shrimps. The worms blocking the bile passages cause clonorchiasis, which finally may become the biliary cirrhosis.
