Immunization with merozoite surface protein 4/5 (MSP4/5), the murine malaria homologue of Plasmodium falciparum MSP4 and MSP5, has been shown to protect mice against challenge by parasites expressing the homologous form of the protein. The gene encoding MSP4/5 was sequenced from a number of Plasmodium yoelii isolates in order to assess the level of polymorphism in the protein. The gene was found to be highly conserved among the 13 P. yoelii isolates sequenced, even though many of the same isolates showed pronounced variability in their MSP1(19) sequences. Nonsynonymous mutations were detected only for the isolates Plasmodium yoelii nigeriensis N67 and Plasmodium yoelii killicki 193L and 194Z..
