n. a condition caused by the presence of the parasitic fluke Opisthorchis in the bile ducts. The infection is acquired through eating raw or undercooked fish that contains the larval stage of the parasite. Heavy infections can lead to considerable damage of the tissues of the bile duct and liver, progressing in advanced cases to cirrhosis. Symptoms may include loss of weight, abdominal pain, indigestion, and sometimes diarrhoea. The disease is treated with praziquantel.
