Antigenic Structure of Plasmodium vinckei

Abstract
An erythrocyte-free preparation of the erythrocytic stages of Plasmodium vinckei was made from infected mouse blood and disintegrated in a Hughes press. Rabbit antisera yielded a series of precipitation arcs against plasmodial extract when examined by immunoelectrophoresis. No arcs developed when uninfected mouse erythrocytes or stromata were tested against the same antiserum.
