BackgroundNon-human primates (NHPs) as a source for Plasmodium infections in humans are a challenge for malaria elimination. In Brazil, two species of Plasmodium have been described infecting NHPs, Plasmodium brasilianum and Plasmodium simium. Both species are infective to man. Plasmodium brasilianum resembles morphologically, genetically and immunologically the human quartan Plasmodium malariae. Plasmodium brasilianum naturally infects species of non-human primates from all New World monkey families from a large geographic area. In the family Callitrichidae only the genus Saguinus has been described infected so far. The present study describes the natural infection of P. brasilianum in tamarins and marmosets of the genera Callithrix, Mico and Leontopithecus in the Atlantic forest.
