Abstract
Cercariae of Schistosomatium douthitti Price, 1931 have been found in two lakes of Manitoba, in which cases of schistosome dermatitis occurred. One adult female Schistosomatium douthitti was recovered from a naturally infected meadow-vole, Microtus pennsylvanicus. This is the first report of the parasite in Manitoba. Cercaria elvae Miller, 1923 was also widespread throughout the southern region of the province.
