Immunodiffusion studies on Schistosoma mansoni and its intermediate host stage specific antigens. 3. Immunoelectrophoresis cross-reactions between S. mansoni stages and Biomphalaria sp. hepato-pancreas antigens.

IMMUNOELECTROPHORESIS was applied for cross-wise checking of the different stages in the life cycle of schistosoma mansoni with extracts of hepato-pancreas from its intermediate host snails Biomphalaria glabrata and Biomphalaria alexandrina. Only few fractions were common to non infected snail organ and parasite development stage, while more crossreactions were detected with infected snail hepato - pancreas.
