Plasmodium malariae is a parasitic protozoan that causes malaria in humans. It is one of several species of Plasmodium parasites that infect other organisms as pathogens, also including Plasmodium falciparum and Plasmodium vivax, responsible for most malarial infection.
In some hosts, invasion of erythrocytes by Plasmodium species can result in disease, called malaria. This can sometimes be severe, rapidly followed by death of the host (e.g. P. falciparum in humans). In other hosts, Plasmodium infection can apparently be asymptomatic. [10]
Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of Plasmodium that causes malaria in humans. [2] The parasite is transmitted through the bite of a female Anopheles mosquito and causes the disease's most dangerous form, falciparum malaria. P. falciparum is therefore regarded as the deadliest ...
The genome of Plasmodium falciparum was sequenced and published in the year 2002. [342] A species of malaria plasmodium tends to have rather polymorphic antigens which can serve as immune system targets. Some searches of P. falciparum genes for hotspots of encoded variations found sections of genes that when tested proved to encode for antigens.
A new species - Plasmodium malagasi - was provisionally identified in the lemur. This species seems likely to belong to the Vinckeia subgenus but further work is required. A study of ~3000 wild ape specimens collected from Central Africa has shown that Plasmodium infection is common and is usually with multiple species. [64]
This suggests that human infection with this species may as previously suspected be a zoonosis. 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. [23] These two species separated between 1.0 and 3.5 million years ago ...
Plasmodium vivax is a protozoal parasite and a human pathogen.This parasite is the most frequent and widely distributed cause of recurring malaria. [2] Although it is less virulent than Plasmodium falciparum, the deadliest of the five human malaria parasites, P. vivax malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen).
It is specifically caused by the Plasmodium malariae species, one of the six species of the protozoan genus Plasmodium. Quartan fever is a form of malaria where an onset of fever occurs in an interval of three to four days, hence the name "quartan". [2] It is transmitted by bites of infected female mosquitoes of the genus Anopheles. Symptoms ...
