Experimental data of the developing of S. mansoni cercariae of two strains (Belo Horizonte, MG and S. José dos Campos, SP), penetrating through the tails of Mus musculus, were analysed. The data led to conclude that there is no numerical difference, in the two strains, as for development from cercariae to adult worm.
