Swimmer's itch--Minnesota; Snails--Parasites; Lymnaea stagnalis


A preliminary study was conducted to determine the causative agents of schistosome dermatitis ( "swimmer's itch") in Minnesota and to determine the incidence schistosome infection in vector snails. A total of 1180 snails were collected from ten different localities, eight of which were sites of known schistosome activity . The incidence of schistosome infection in snails from individual areas was always less than 10 percent. Cercariae of Trichobilharzia ocellata from Lymnaea stagnalis were the most frequently-found schistosomes in our study.
