liver fluke

One of several types of flatworm (trematode) which can gain access to the liver by way of the bile duct and cause a feverish illness with liver tenderness and enlargement. The common form of liver fluke, Fasciola hepatica , is a parasite of sheep which produces eggs that are passed in the sheep faeces. The intermediate host is an aquatic snail from which further larvae are released to congregate on the leaves of water plants such as cress or water-chestnut. If these are eaten by humans, the infestation may be acquired. Diagnosis is by microscopic identification of the fluke eggs in the stools. ANTHELMINTIC drugs are used to kill the worms.
