IMMUNOELECTROPHORESIS was applied to evaluate the immunologic relationship between the different stages in the life cycle of Schistosoma mansoni (S.m.). The preparation of antigens and antisera was described. Separated female and male adult worms tested seem to be identical. Eggs, miracidia and cercariae from Biomphalaria glabrata and Biomphalaria alexandrina showed varying degree of cross-reactions. The maximal number of pricipitin arcs was observed, when anti-miracidia-serum was checked against all other S.m. antigens.
