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).
Malaria prophylaxis is the preventive treatment of malaria. Several malaria vaccines are under development. For pregnant women who are living in malaria endemic areas, routine malaria chemoprevention is recommended. It improves anemia and parasite level in the blood for the pregnant women and the birthweight in their infants. [1]
Electron micrograph of a Plasmodium falciparum-infected red blood cell (center), illustrating adhesion protein "knobs" Malaria infection develops via two phases: one that involves the liver (exoerythrocytic phase), and one that involves red blood cells, or erythrocytes (erythrocytic phase). When an infected mosquito pierces a person's skin to ...
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.

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.
That became the National Communicable Disease Center in 1967, the Center for Disease Control in 1970, the Centers (plural) for Disease Control in 1980 and the Centers for Disease Control and Prevention in 1992. [5] During the CDC's first few years, more than 6,500,000 homes were sprayed with the insecticide DDT. DDT was applied to the interior ...
For the prevention of relapse in P. vivax and P. ovale 0.15 mg/kg should be given for 14 days. As a gametocytocidal drug in P. falciparum infections a single dose of 0.75 mg/kg repeated seven days later is sufficient. This treatment method is only used in conjunction with another effective blood schizonticidal drug.
