Plas·mo·di·um know·le·si

a species of protozoan from Southeast Asia that causes monkey malaria with a quotidian fever cycle; highly fatal in rhesus monkeys; naturally acquired by a human in Malaysia, and also transmitted to humans experimentally.

Plasmodium knowlesi

A species found in Southeast Asia. It is structurally similar to P. malariae. Although it primarily infects other primates, it can infect humans and produce a debilitating febrile illness.

Plasmodium falciparum, Plasmodium malariae, Plasmodium ovale, Plasmodium vivax
the causes of the four specific types of human malaria. They are transmitted to the bloodstream of humans by the bite of anopheline mosquitoes. The sporozoites migrate and are transported via the blood stream to the liver, where they develop and multiply within the parenchymal cells as merozoites, which then burst the liver cells and invade erythrocytes. Some of the merozoites develop into gametocytes, which are ingested by mosquitoes, beginning the sexual stage, which ends with the development of sporozoites.

occurs in fowls and transmissible to some other birds; many are resistant.
