[Resistance of Biomphalaria peregrina of Santa Rita do Sapucaí, Minas Gerais, Brazil to infection with 3 strains of Schistosoma mansoni].
The descendants of the planorbid snail Biomphalaria peregrina, collected in the region of Santa Rita do Sapucaí, Minas Gerais, Brazil, were exposed to miracidia of three strains of Schistosoma mansoni: "LE" strain from Belo Horizonte, State of Minas Gerais; "SJ", strain from São José dos Campos, State of São Paulo and "AL" strain from State of Alagoas. Of 300 snails exposed to miracidia of the three strains, none was infected.
