Serotyping Plasmodium falciparum from acute human infections using monoclonal antibodies.

Monoclonal antibodies specific for the schizont and merozoite stages of Plasmodium falciparum have been used to demonstrate antigenic differences between parasites obtained from individual patients with acute malaria. Parasites from East Africa are shown to share some strain-specific antigenic determinants with culture-adapted isolates from Africa as well as from Asia and Papua New Guinea.
