English: A mosquito causes an infection by a bite (1). The sporozoites enter the bloodstream, and migrate to the liver. They infect liver cells, where they multiply into merozoites, rupture the liver cells, and return to the bloodstream (2).

In 1880, Alphonse Laveran discovered that the causative agent of malaria is a parasite. [2] Detailed work of Golgi in 1886 demonstrated that in some patients there was a relationship between the 72-hour life cycle of the parasite and the chill and fever patterns in the patient. [2] The same observation was found for parasites with 48-hour ...
The life cycle of malaria parasites: Sporozoites are introduced by a mosquito bite. When they reach the liver, they multiply into thousands of merozoites. The merozoites infect red blood cells and replicate, infecting more and more red blood cells. Some parasites form gametocytes, which are taken up by a mosquito, continuing the life cycle.
Such gametes can fuse within the mosquito to form a diploid (2N) plasmodium zygote, the only diploid stage in the life cycle of these parasites. [56] The zygote can undergo another round of chromosome replication to form an ookinete (4N) (see Figure: Life cycle of plasmodium). The ookinete that differentiates from the zygote is a highly mobile ...
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
A trophozoite (G. trope, nourishment + zoon, animal) is the activated, feeding stage in the life cycle of certain protozoa such as malaria-causing Plasmodium falciparum and those of the Giardia group. [1] The complementary form of the trophozoite state is the thick-walled cyst form. They are often different from the cyst stage, which is a ...
