Related to trematode: cestode


an organism of the class trematoda, characterized by a body that is usually flat and often leaflike; flukes can infect the blood, liver, intestines, and lungs. Called also trematode.

Flukes are not common in the United States but are a serious problem in many Asian, tropical, and subtropical countries. The Chinese liver fluke, Clonorchis sinensis, enters the body in raw or improperly cooked fish and may cause enlargement of the liver, jaundice, anemia, and weakness. Another liver fluke, Fasciola hepatica, is occasionally found in humans; it causes obstruction of the bile ducts and enlargement of the liver. Blood flukes such as Schistosoma penetrate the skin, make their way to the blood and travel to various parts of the body (see also schistosomiasis).

Treatment varies according to the type of fluke involved and requires careful medical supervision. Proper cooking of fish provides protection against liver fluke infection. Since snails are carriers of flukes, their destruction, usually by poison, is an effective preventive measure in areas where fluke infection is a problem.
