Studies on experimental mixed infection of schistosoma haematobium and schistosoma mansoni

ABSTRACT

Swiss albino mice have been infected with S. hematobium and challenged four weeks later with S. mansoni. Parasitological, pathological and ultrastructural studies were done. The results revealed cross mating between the two species. A reduction in S. mansoni worm load, egg count, hepatic granuloma number and size was noticed. The presence of heterologous immunity was suggested
