Investigations on anopheline mosquitoes close to the nest sites of chimpanzees subject to malaria infection in Ugandan Highlands
Abstract Background Malaria parasites ( Plasmodium sp.), including new species, have recently been discovered as low grade mixed infections in three wild chimpanzees ( Pan troglodytes schweinfurthii ) sampled randomly in Kibale National Park, Uganda. This suggested a high prevalence of malaria infec...

Abstract Background Malaria parasites ( Plasmodium sp.), including new species, have recently been discovered as low grade mixed infections in three wild chimpanzees ( Pan troglodytes schweinfurthii ) sampled randomly in Kibale National Park, Uganda.
