[Changes in fluorescent antibodies in experimental bilharziasis with S. mansoni and S. haematobium in mice. Comparison of the results obtained using homologous and heterologous antigens].

Fluorescent antischistosomiasis antibodies appear earlier in mice infected by 150/200 cercariae than in those who only received 20. The use of a homologous antigen in mice infected by S. mansoni or S. haematobium allows earlier and more important responses. The infections by S. haematobium seem to determinate in mice a more important immune responsiveness. Is it a specific parasitic manifestation (S. mansoni being better adapted to rodents?).
