Wild reservoirs of Schistosoma mansoni from Caratinga, an endemic schistosomiasis area of Minas Gerais State, Brazil.

Among 472 small mammals trapped in the Caratinga area of Minas Gerais, Brazil, Schistosoma mansoni infection was demonstrated in 6 of 9 Procyon, 1 of 7 Didelphis, 1 of 1 Philander, 25 of 72 Nectomys, and 16 of 383 various other rodents representing 20 species. The role of Nectomys and Procyon in maintaining endemicity needs further investigation.
