Susceptibility of the Gibbon Hylobates lar to Falciparum Malaria

Abstract

The splenectomnized juvenile gibbon, Hylobates lar, is susceptible to infection with trophozoites of Plasmodium falciparum. All subjects in a group of six animals that were injected with freshly collected blood from four infected humans in Saraburi Province, Thailand, developed parasitemia 2 to 20 days later; infections were transmitted from one of these subjects to three clean gibbons.
