How do you classify Plasmodium?

Plasmodium is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes. Within Apicomplexa, Plasmodium is in the order Haemosporida and family Plasmodiidae.

What are the characteristics of Plasmodium vivax?

P. vivax trophozoites show amoeboid cytoplasm, large chromatin dots, and have fine, yellowish-brown pigment. Schüffner’s dots may appear more fine in comparison to those seen in P. ovale.

How many species of Plasmodium vivax are known?

There are approximately 156 named species of Plasmodium which infect various species of vertebrates. Four species are considered true parasites of humans, as they utilize humans almost exclusively as a natural intermediate host: P. falciparum, P.

Which type of malaria is caused by Plasmodium vivax?

vivax has long been known as ‘benign tertian malaria‘, that dogma of harmlessness has been revealed as fallacious. 2,5 Among patients hospitalized with a primary diagnosis of vivax malaria, about 10–20% will be classified as having severe illness, and 5%–15% of those will not survive.

What is the common name for Plasmodium vivax?

vivax malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen). P.
…
Plasmodium vivax
Genus:Plasmodium
Species:P. vivax
Binomial name
Plasmodium vivax (Grassi & Feletti, 1890)

What is Plasmodium vivax an example of?

Malaria parasites are micro-organisms belonging to the genus Plasmodium. The primary host of the parasite is the Anopheles mosquito and vertebrates (primarily humans). Malaria parasites are transmitted from the mosquito to its human host in the form of sporozoites during a blood meal.

What is the infective stage of Plasmodium vivax?

sporozoites
Solution : The infective stage of plasmodium to man is sporozoite. The sporozoites are small, spindle – shaped, slightly curved and uninucleate organisms.

What are the four types of malaria?

The Disease

Four kinds of malaria parasites infect humans: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae.

What are the 5 types of malaria?

Five species of Plasmodium (single-celled parasites) can infect humans and cause illness:
  • Plasmodium falciparum (or P. falciparum)
  • Plasmodium malariae (or P. malariae)
  • Plasmodium vivax (or P. vivax)
  • Plasmodium ovale (or P. ovale)
  • Plasmodium knowlesi (or P. knowlesi)

What are the characteristics of Plasmodium malariae?

malariae trophozoites have compact cytoplasm and a large chromatin dot. Occasional band forms and/or “basket” forms with coarse, dark-brown pigment can be seen. Trophozoite in a thick blood smear. Band-form trophozoites in thin blood smears.

What is the morphology of Plasmodium vivax?

Plasmodium vivax morphology is distinctive by infected enlarged erythrocytes, which appear like granules over the erythrocytes. These granules are caused by caveola complexities over the erythrocytes. Plasmodium vivax morphology is identical to P. ovale also.

What is Plasmodium vivax Class 11?

Plasmodium vivax is a protozoan causing malaria. It is a parasite. It is carried by female Anopheles mosquitoes to humans.

How is Plasmodium vivax diagnosed?

The accurate diagnosis of vivax malaria in an acutely ill patient seeking routine care requires microscopy examination of a Giemsa-stained blood smear (microscopy), or use of an immunochromatographic cassette containing monoclonal antibodies to a P. vivax antigen (rapid diagnostic test [RDT]).

What is the infective stage of Plasmodium vivax?

sporozoites
Solution : The infective stage of plasmodium to man is sporozoite. The sporozoites are small, spindle – shaped, slightly curved and uninucleate organisms.

  • Plasmodium malariae (or P. malariae)
  • Plasmodium vivax (or P. vivax)
