Plasmodium falciparum

Plasmodium falciparum is a single-celled parasite that causes falciparum malaria, the most severe form of human malaria. It infects liver cells and red blood cells and is transmitted by Anopheles mosquitoes.

Plasmodium life cycle: The sequence of developmental stages Plasmodium parasites pass through in mosquito and vertebrate hosts. This cycle shows how the parasite moves between mosquitoes, liver cells, and red blood cells.
Malaria: A mosquito-borne disease caused by Plasmodium parasites, with fever and potentially severe organ complications. Falciparum malaria is one species-specific form of this human disease.
Alphonse Laveran: A French physician who identified malaria parasites in human blood in 1880. His discovery established that a parasite, rather than a bacterium, causes malaria.
Plasmodium vivax: A Plasmodium species that causes malaria and can persist through dormant liver stages. Unlike P. falciparum, P. vivax can relapse from dormant hypnozoites.
Anopheles mosquito: A mosquito genus whose females transmit malaria parasites while taking blood meals. Female Anopheles mosquitoes inject sporozoites that begin falciparum infection.
Malaria diagnosis: The laboratory and clinical methods used to identify malaria infection and determine its severity. Microscopy and rapid tests detect falciparum infection and guide urgent treatment.
Ronald Ross: A British medical doctor who demonstrated malaria transmission by mosquitoes in birds in 1897. His work helped establish the mosquito transmission route used by human Plasmodium parasites.
Plasmodium malariae: A Plasmodium species that causes a generally chronic, often low-density human malaria infection. Its typically slower, less severe course contrasts with falciparum malaria.
Sporozoite: A motile, infective stage of Plasmodium that develops in the mosquito and enters a vertebrate host. Sporozoites travel from the bite site to the liver to start the human phase.
Artemisinin-based combination therapy: A malaria treatment pairing an artemisinin derivative with a longer-acting antimalarial drug. These combinations are the standard treatment for uncomplicated falciparum malaria.
