Experimental Evaluation of the Pathogenicity of Different Strains of Schistosoma mansoni

Table 2

Mean numbers of mating worm pairs, total number of worms, and mean percentages of worm recovery relative to the number of penetrating cercariae in mice infected with BH, SJ, and SD strains of S. mansoni and sacrificed at the eighth week of infection.
