Resumo: Wild (W) and human (H) strains of Schistosoma mansoni were isolated in the lowland region of Maranhão State (northeastern Brazil). Snail progenies of Biomphalaria tenagophila collected from Paraiba do Sul River valley (Southeastern Brazil) were exposed to W miracidia, obtained from livers of wild rodents,and to H miracidia, from eggs in human stools. The date of elimination of cercariae, the quantity of eliminated larvae, the infection index of the moluscs and the mortality rate of the snails were recorded. This data suggest better adaptation of the W strain than of the H strain to B. tenagophila. These results were compared with published data of H and W strains from the Paraiba do Sul River valley and similar parasitological behavior was found.

Exemplares de Biomphalaria tenagophila, provenientes do Vale do Rio Paraíba do Sul (São Paulo, Brasil), foram expostos às linhagens humana (H) e silvestre (S) de Schistosoma mansoni, oriundos da Região da Baixada Maranhense, ao noroeste do Estado do Maranhão. As linhagens H e S apresentaram comportamento distinto quando colocadas à infectar os moluscos paulistas. As B. tenagophila infectadas com a linhagem S apresentaram índice de mortalidade inferior ao observado nas infectadas com a linhagem H. No molusco paulista a linhagem silvestre maranhense completou seu desenvolvimento, fato que não ocorreu com a linhagem humana. Estas observações foram comparadas com os resultados anteriormente obtidos, quando estudou-se o comportamento das linhagens H e S do Vale do Rio Paraíba do Sul no molusco simpátrico. Foi verificado que as linhagens maranhenses e paulistas quando comparadas apresentavam comportamento similar frente a B. tenogophila do Vale do Rio Paraíba do Sul, SP. Universidade de São Paulo.
