A comparative study of the death of schistosomula ofSchistosoma haematobiumandSchistosoma mansoniin the skin of mice and hamsters

Abstract

AbstractThis study shows that some cercariae ofS. haematobiumandS. mansonidie during penetration of mouse or hamster skin.Approximately 30–38% of cercariae of both species die in mouse skin and 14–16% die in hamster skin. The greater number of cercariae which die in the skin of mice seems to account for the higher yield of adult worms recovered in hamsters. Adult worm recoveries from animals infected withS. haematobiumwere, however, only about half the worm recoveries from hosts infected withS. mansoni.
