Clinical Presentation

Metorchiasis is caused by the liver fluke parasite Metorchis conjunctus (aka Distoma conjunctum or Parametorchis canadense) . First reported in 1960 by Cobbold, M conjunctus is best known as a killer of Canadian sled dogs who eat raw fish infected with its metercaricae. Though human infection is rare, it has been found to cause acute and possible chronic illness in native communities in Canada. The largest outbreak is documented by J Dick MacLean et al. in 1993 and involved 27 people who ate sashimi made from infected white sucker fish. (In its family are the more prevalent and better-documented Chinese liver flukes.)
