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.

a genus of apicomplexan protozoa in the family Plasmodiidae parasitic in the blood cells of animals and humans; the malarial parasite. See also avian malaria.

Plasmodium berghei
occurs naturally in tree rats; transmissible experimentally to other rodents.
Plasmodium brasilianum
occurs in several monkey species, transmissible experimentally to humans and marmosets.
Plasmodium cathemerium
occurs in passerine birds including sparrows, blackbirds.
Plasmodium chabaudi
occurs in tree rats, transmissible to mice.

Plasmodium durae
occurs in turkeys, transmissible to ducks.
Plasmodium elongatum
transmissible experimentally to sparrow, canaries, ducks.
Plasmodium eylesi
found in gibbon monkeys.
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.
Plasmodium fallax
occurs in guinea fowl; transmissible to other birds.
Plasmodium gallinaceum
occurs in fowls and transmissible to some other birds; many are resistant.
Plasmodium gonderi
occurs in mandrills, mangabeys, rhesus monkeys.
Plasmodium griffithsi
occurs in turkeys.
Plasmodium hexamerium
found in passerine birds.

found in several species of monkeys.
Plasmodium juxtanucleare
occurs in fowls; transmitted experimentally to turkeys.

occurs in several species of monkeys.
Plasmodium lophurae
occurs in pheasants; experimentally transmitted to chickens and ducklings.
Plasmodium reichenowi
occurs in chimpanzee and gorilla.
Plasmodium relictum
occurs in a variety of bird species.
Plasmodium rouxi
found in sparrows and finches.
Plasmodium schwetzi
occurs in chimpanzee and gorilla; transmissible experimentally to humans.
Plasmodium simium
occurs in howler monkeys and humans.
Plasmodium vaughani
found in many bird species.
