Abstract
Rat erythrocytes parasitized with Plasmodium berghei were found to release soluble antigenic products in vitro. The supernatants obtained by centrifugation of the disrupted cells induced specific transformation of non-adherent spleen lymphocytes of convalescent rats and produced precipitation lines with antiplasmodial antibodies. In a preliminary experiment they also immunized young rats against a viable challenge of P. berghei. It is suggested that the soluble material could serve for the purification of an effective protective antigen.
