Summary

The virulence of the four geographic strains of S. japonicum was found to be different in mice infected with 100 cercariae. Judging from the host's survival times after inoculation and after the appearance of eggs in the feces, the Japanese and Philippine strains of this schistosome species were shown to be more virulent than the Chinese and Formosan strains.
