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).
Schüffner's dots refers to a hematological finding that is associated with malaria, [1] exclusively found in infections caused by Plasmodium ovale or Plasmodium vivax. [ 2 ] Plasmodium vivax induces morphologic alterations in infected host erythrocytes that are visible by light microscopy in Romanowsky-stained blood smears as multiple brick ...
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.
A difference between the susceptibility to Plasmodium vivax malaria has been reported. [76] Erythrocytes expressing Fya had 41-50% lower binding of P. vivax compared with Fyb cells. Individuals with the Fy(a+b-) phenotype have a 30-80% reduced risk of clinical vivax but not falciparum malaria.
Organisms whose life cycles rely on this process include Theileria, Babesia, [4] Plasmodium, [5] and Toxoplasma gondii. Sporogony is a type of sexual and asexual reproduction. It involves karyogamy, the formation of a zygote, which is followed by meiosis and multiple fission. This results in the production of sporozoites.
[citation needed] The initial focus of MAP centred on predicting the endemicity of Plasmodium falciparum, [5] the most deadly form of the malaria parasite, due to its global epidemiological significance and its better prospects for elimination and control. Work in 2009 began to map the extent and burden of the relatively neglected Plasmodium vivax.
Plasmodium is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects.The life cycles of Plasmodium species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal.
Within the subgenus Plasmodium, P. vivax groups with an Asian clade which appears to be rooted in Africa. P. malaria and P. ovale both belong to an African clade and are more closely related to each other than to P. vivax. Within the subgenus Laverinia P. falciparum and P. reichenowi form a clade while the other four known species form a second ...
