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 ...
P. vivax is also known to infect orangutans [20] and the brown howler monkey (Alouatta guariba clamitans) [10] P. vivax has been reported from chimpanzees living in the wild. [13] It has been suggested that vivax infection of the great apes in Africa may act as a reservoir given the prevalence of Duffy antigen negative humans in this area. [21 ...
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.
Plasmodium is a eukaryote but with unusual features. The genus Plasmodium consists of all eukaryotes in the phylum Apicomplexa that both undergo the asexual replication process of merogony inside host red blood cells and produce the crystalline pigment hemozoin as a byproduct of digesting host hemoglobin. [2]
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 ...
Subgenus Plasmodium Bray 1963 emend. Garnham 1964; Subgenus Sauramoeba Garnham 1966; Subgenus Vinckeia Garnham 1964; Genus Polychromophilus Landau et al 1984; Genus Rayella Dasgupta 1967; Genus Saurocytozoon Lainson & Shaw 1969; Genus †Vetufebrus Poinar 2011; The genus Mesnilium is the only taxon that infects fish. The genus has a single ...
Plasmodium cynomolgi is the second-most studied malaria parasite of non-human primates after Plasmodium knowlesi, primarily due to its similarity to the human parasite P. vivax. [10] In particular, P. cynomolgi is used as a model for hypnozoite biology as it (along with P. vivax ) is one of the few Plasmodium species known to have this ...
