FLUKE DISEASE IN NORTHERN MANITOBA SLEDGE DOGS

Abstract

An opisthorchiid Trematode, Parametorchis manitobensis n.sp. is recorded from the livers of sledge dogs from northern Manitoba. A key is given to the known species of Parametorchis. Infection with the trematode produces chronic cirrhosis and anemia, followed by muscular weakness and death. Infection is believed to be contracted by ingestion of metacercariae in Catostomus commersonii and prophylaxis would consist of the thorough boiling of such fish before use as dog food.
