Plasmodium knowlesi: A Malaria Parasite of Monkeys and Humans

Plasmodium knowlesi is a malaria parasite of monkeys of Southeast Asia that is transmitted by mosquitoes of the Anopheles leucosphyrus group. Humans are frequently infected with this parasite and misdiagnosed as being infected with Plasmodium malariae. The parasite was a major monkey animal model for developing antimalarial vaccines and investigations of the biology of parasite invasion. P. knowlesi is the first monkey malaria parasite genome to be sequenced and annotated.
