Metorchis conjunctis(met-ōr'kis kon-jŭnk'tis),
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 (for example, fish-eating mammals in North America). Several snail species serve as intermediate hosts that shed cercariae that penetrate and encyst in several fish species (for example, 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.
