Malaria is caused by infection with parasites in the genus Plasmodium. [44] In humans, malaria is caused by six Plasmodium species: P. falciparum, P. malariae, P. ovale curtisi, P. ovale wallikeri, P. vivax and P. knowlesi. [45] Among those infected, P. falciparum is the most common species identified (~75%) followed by P. vivax (~20%). [14]
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 rodhaini Brumpt, 1939. 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 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. It is responsible for around 50% of all malaria cases.
Prevalence of malaria in 2009. A. aegypti only and dengue distribution in 2006. Mosquito-borne diseases or mosquito-borne illnesses are diseases caused by bacteria, viruses or parasites transmitted by mosquitoes. Nearly 700 million people contract mosquito-borne illnesses each year, resulting in more than a million deaths.
It accounts for 80% of malaria deaths. Therefore, mutations that protect against malaria infection and lethality pose a significant advantage. [citation needed] Malaria has placed the strongest known selective pressure on the human genome since the origin of agriculture within the past 10,000 years.
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. Parasites grow within a vertebrate body tissue (often the liver) before entering ...
The mainstay of malaria diagnosis has been the microscopic examination of blood, utilizing blood films. [1] Although blood is the sample most frequently used to make a diagnosis, both saliva and urine have been investigated as alternative, less invasive specimens. [2] More recently, modern techniques utilizing antigen tests or polymerase chain ...
