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.
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 take a blood meal, sporozoites in the mosquito's saliva enter the bloodstream and migrate to the liver where they infect ...
The ensuing destruction of host red blood cells can result in malaria. During this infection, some parasites are picked up by a blood-feeding insect (mosquitoes in majority cases), continuing the life cycle. [1] Plasmodium is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes.
Plasmodium knowlesi is a parasite that causes malaria in humans and other primates. It is found throughout Southeast Asia, and is the most common cause of human malaria in Malaysia. Like other Plasmodium species, P. knowlesi has a life cycle that requires infection of
The Malaria lifecycle is divided into two phases: Human: The infected female mosquito (usually Anopheles species) bites a human and injects sporozoites into the bloodstream during a bloodmeal. [8] The sporozoites travel to the liver where they invade liver cells (hepatocytes) in the Exo-erythrocytic Cycle. [9]
This is caused by parasite-derived cell surface proteins being present on the erythrocyte membrane, and it is these proteins that bind to receptors in human cells. Sequestration in the brain causes cerebral malaria, a very severe form of the disease, which increases the victim's likelihood of death.
As the planet warms, mosquitoes are slowly migrating upward. The temperature range where malaria-carrying mosquitoes thrive is rising in elevation. Scientists now worry people living in areas once ...
A merosome is a life stage of malaria parasites of the genus Plasmodium. After injection by mosquitoes into the human host, malaria parasites first migrate to liver cells (hepatocytes), where they replicate asexually inside the host cell. Afterwards, they go on to infect red blood cells.
