Immunodiffusion studies on Schistosoma mansoni and its host stage specific antigens. 2. Immunoelectrophoresis cross-reactions between hepato-pancreas of Biomphalaria glabrata and Biomphalaria alexandrina.

Abstract

IMMUNOELECTROPHORESIS was used for studies on immunological cross-reactions between both Schistosoma mansoni (S. m.) intermediate host snails Biomphalaria glabrata and Biomphalaria alexandrina. The preparation of antigens and their corresponding antisera from hepato-pancreas of S. m. infected and non infected snails was described as the homologous reactions of both snails either infected or non infected were rather similar, close immunological relationship between B. glabrata and B. alexandrina could be deduced.
