Metorchis conjunctis

Pronunciation: met-or'kis kon-junk'tis

Definition: Liver fluke of Opisthorchidae family found in temperate to subarctic regions of North America and Eurasia. Adults are 3–4 mm by 5–8 mm long and live in the biliary tree of the definitive host (fish-eating mammals in North America). Several snail species serve as intermediate hosts that shed cercariae that penetrate and encyst in several fish species (Catostoma commercialis). Humans can become incidental hosts when they eat raw or poorly cooked fish flesh. Symptoms of acute infection include fever, eosinophilia, and right upper quadrant pain.
