Some of the behavioral aspects of the Minas Gerais and S. Paulo states' strains Schistosoma mansoni, concerning the penetration capability of cercariae of each strain and the relationship between hepatic granulomata and worms, were studied. The Minas Gerais' strain cercariae present more penetration capability and the ratio between the numbers of hepatic granulomata and number of worms varied inversely with the number of infecting worms per mouse, in both strains.
