Plasmodium in erythrocytic cycle. Plasmodium, a genus consisting of over 170 species, infects mammals, reptiles, birds, and amphibians.Blood parasites of the Plasmodium genus cause malaria, which most commonly infect vertebrates with only four strains known to infect humans. [2]
Blackwater fever is caused by heavy parasitization of red blood cells with Plasmodium falciparum. However, there have been other cases attributed to Plasmodium vivax, [1] Plasmodium malariae, [2] Plasmodium knowlesi. [3] Blackwater fever is a serious complication of malaria, but cerebral malaria has a higher mortality rate.
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 ...
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]
Nearly 200 Plasmodium species have been identified that infect birds, reptiles, and other mammals, [362] and about 30 of them naturally infect non-human primates. [363] Some malaria parasites of non-human primates (NHP) serve as model organisms for human malarial parasites, such as P. coatneyi (a model for P. falciparum ) and P. cynomolgi (a ...
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 ...
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).
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.
