Plasmodium species infecting primates
Species of Plasmodium infecting humans
- Plasmodium cynomolgi bastianellii
The first six listed here are the most common species that infect humans. With the use of the polymerase chain reaction additional species have been and are still being identified that infect humans.
One possible experimental infection has been reported with Plasmodium eylesi. Fever and low grade parasitemia were apparent at 15 days. The volunteer (Dr Bennett) had previously been infected by Plasmodium cynomolgi and the infection was not transferable to a gibbon (P. eylesi 's natural host) so this cannot be regarded as definitive evidence of its ability to infect humans. A second case has been reported that may have been a case of P. eylesi but the author was not certain of the infecting species.[4]
A possible infection with Plasmodium tenue has been reported.[5] This report described a case of malaria in a three year old black girl from Georgia, USA who had never been outside the US. She suffered from both P. falciparum and P. vivax malaria and while forms similar to those described for P. tenue were found in her blood even the author was skeptical about the validity of the diagnosis.
Confusingly Plasmodium tenue was proposed in the same year (1914) for a species found in birds. The human species is now considered to be likely to have been a misdiagnosis and the bird species is described on the Plasmodium tenue page.
Notes
Until recently the only known host of P. falciparum was humans but this species has also been described in gorillas (Gorilla gorilla)[6] and bonbos[7] There has been a single report of P. falciparum in a brown howler monkey (Alouatta guariba) and in black howler monkeys (Alouatta caraya)[8] but until this is confirmed its validity should be considered dubious.
A species that clusters with P. falciparum and P. reichenowi has been identified in Gabon, Africa in chimpanzees (Pan troglodytes).[9] This appears to have diverged from these two species about 21 million years ago. It has only been identified from the sequence of its mitochondrion to date and further work is needed to characterise the species. A second report has confirmed the existence of this species in chimpanzees.[6] A third report has confirmed the existence of this species.[10]
Two additional species within the subgenus Laverania have been identified on the basis of DNA sequences alone: Plasmodium billbrayi and Plasmodium billcollinsi.[6] and bonbos[7] P. billbrayi was found in two subspecies of chimpanzee (Pan troglodytes troglodytes and Pan troglodytes schweinfurthii). P. billcollinsi was found in only one subspecies of chimpanzee (Pan troglodytes troglodytes). Further work is needed to characterise these species.
Humans are currently considered to be the only host for P. malariae. However Rodhain and Dellaert in the 1940s showed with transmission studies that P. malariae was present in chimpanzees.[11][12] The presence of P. malaria in chimpanzees has been reported in Japan suggesting that this species may be able to act as a host.[13] A second paper has described the presence of P. malaria in wild chimpanzees.[10] Another paper has reported several cases of P. malariae in brown howler monkey (Alouatta guariba) and black howler monkeys (Alouatta caraya)[8] It has been shown that splectomised three-striped night monkey (Aotus trivirgatus) can be infected with P. malariae.[14] The existence of multiple independent reports seem to suggest that the chimpanzee and possibly other species may act as a host to P. malaria at least occasionally.
P. vivax will infect chimpanzees. Infection tends to be low grade but may be persistent and remain as source of parasites for humans for some time. P. vivax is also known to infect orangutans[15] and the brown howler monkey (Alouatta guariba clamitans)[8] P. vivax has been reported from chimpanzees living in the wild.[10]
Like P. vivax, P. ovale has been shown to be transmittable to chimpanzees. P. ovale has a unusual distribution pattern being found in Africa, Myanmar the Philippines and New Guinea. In spite of its admittedly poor transmission to chimpanzees given its discontigous spread, it is suspected that P. ovale may in fact be a zooenosis with an as yet unidentified host. If this is actually the case, the host seems likely to be a primate. A report has been published suggesting that P. ovale may be a natural parasite of chimpanzees[16] but this needs confirmation. P. ovale has since been described from chimpanzees living in the wild.[10] This suggests that human infection with this species may as previously suspected be a zooenosis.
It has been recently shown that P. ovale is actually two genetically distinct species that coexist. These species are Plasmodium ovale curtisi and Plasmodium ovale wallikeri.[17] These two species separated between 1.0 and 3.5 million years ago.
The remaining species capable of infecting humans all have other primate hosts.
Plasmodium shortii and Plasmodium osmaniae are now considered to be junior synonyms of Plasmodium inui
Species previously described as infecting humans but no longer recognised as valid
Taxonomy in parasitology until the advent of DNA based methods has always been a problem and revisions in this area are continuing. A number of synonyms have been given for the species infecting humans that are no longer recognised as valid.[18] Since perusal of the older literature may be confusing some currently defunct species names are listed here.

- P. vivax - P. vivax hibernans, P. vivax chesson and P. vivax multinucleatum.
Interrelatedness - The evolution of these species is still being worked out and the relationships given here should be regarded as tentative. This grouping, while originally made on morphological grounds, now has considerable support at the DNA level.
- P. brasilianum, P. inui and P. rodhaini are similar to P. malariae (quartan malaria group)
- P. cynomolgi, P. fragile, P. knowlesi, P. simium and P. schwetzi are similar to P. vivax
- P. fieldi and P. simiovale are similar to P. ovale
- P. falciparum is closely related to P. reichenowi.
Notes
- P. kochi has been described as a parasite of monkeys. This species is currently classified as Hepatocystis kochi. This may be subject to revision.
- P. brasilianum and P. rodhaini seem likely to be the same species as P. malariae.
- P. lemuris may actually belong to the Haemoproteus genus. Clarification of this point awaits DNA examination.
- P. shortii is currently (2007) regarded as a junior synonym of P. inui.
