Partial Protection of Plasmodium Falciparum-Vaccinated Aotus Trivirgatus against a Challenge of a Heterologous Strain

Abstract

Two Aotus trivirgatus griseimenbra monkeys which had been immunized with the merozoite-enriched FUP strain of Plasmodium falciparum were protected against a primary challenge with the homologous strain. The results described here show that these two monkeys were protected against a subsequent challenge with a heterologous strain (FVO) of P. falciparum. The unimmunized control monkey died of FVO infection by day 18.
