A malacological survey to detect foci of transmission of schistosomiasis and other parasitic diseases was undertaken into water-courses from 13 municipalities of microregion of Belo Horizonte, MG, Brazil. From 1990 to 1996, 22,066 snails were collected. From those, 378 (1.7%) were found infected by trematodes: Biomphalaria glabrata (7,920), infected by Schistosoma mansoni (1.9%), Echinostomatidae (1.2%), Strigeidae (0.6%), Cercaria minense (0.1%) and Derogenidae (-0.1%); B. straminea (4,093) infected by Strigeidae (0.6%), Echinostomatidae (0.2%), Clinostomatidae (-0.1%) and two unidentified cercariae; B. tenagophila (1,338), infected by Strigeidae (0.1%) and Physa marmorata (1,776) by Echinostomatidae (1.6%). The snails Biomphalaria peregrina, B. occidentalis, B. schrammi, Drepanotrema depressissimum, D. lucidum, D. cimex, Physa cubensis, Lymnaea columella, Melania tuberculata, Idiopyrgus souleyetianus, Pomacea sp, Anodontites sp and Ancylidae were found noninfected. Snails from 9 municipalities were infected by S. mansoni and from 11 by other trematodes.
