Experimental systems that model some of the complex interactions between parasite and host can be extremely valuable in identifying and developing new prophylactics and therapeutics against human diseases. Because primates have similar immune systems to humans, we have characterized a baboon model for understanding host response to . Ten intact olive baboons () of either sex were experimentally infected with H strain erythrocytic parasites. The infection in these baboons was either acute or chronic. Animals with acute infection developed multiple system organ dysfunction and cerebral involvement. In chronically infected animals, only the spleen was moderately enlarged. The parasitemia profile in baboons and rhesus monkeys was comparable. However, some clinical symptoms of the baboons and -infected humans were similar. These studies demonstrate for the first time that is a suitable host for for studying clinical symptoms and pathology.
