These hidden parasites (in addition to hypnozoites) are thought to be the origin of instances of recurrent P. vivax malaria. [14] Sporozoites, one of several different forms of the parasite, from a mosquito. Within the red blood cells, the merozoites grow first to a ring-shaped form and then to a larger form called a trophozoite.

Parasitism is a close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life.

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. P. falciparum is therefore regarded as the deadliest ...
Most of these eukaryotic organisms form a symbiotic relationship in animals. These include a variety of forms found in the intestines of termites [2] and cockroaches, many of which have symbiotic bacteria that help them digest cellulose in woody plants. Other species within this supergroup are known parasites, and include human pathogens. [3] [4]
Parasites are organisms which derive sustenance from its host while causing it harm. [2] The study of parasites and parasitic diseases is known as parasitology. [3] Medical parasitology is concerned with three major groups of parasites: parasitic protozoa, helminths, and parasitic arthropods. [2]
