(Zoology) any of the cells formed by fission of a schizont during the life cycle of sporozoan protozoans, such as the malaria parasite. Compare trophozoite

The increase in size continues for 24 hours and at the end of 48 hours these red cells rupture releasing the merozoites.
The liver was characterized by the presence of a few schizonts in hepatocytes and endothelial cells and a very large number of macrophages filled by characteristically shaped basophilic merozoites contained in parasitophorous vacuoles, a typical invagination of the cytoplasmic membrane of host cells that surround the parasites.
(1) Babesiosis can be definitively diagnosed during the acute phase by identifying, on occasion, incidentally, trophozoites or merozoites within erythrocytes on a peripheral blood smear stained with Giemsa or Wright stains, but must be distinguished from Plasmodium spp.
In effect, sialic acid is critical to the mechanical invasion of merozoites into RBCs; consequently, individuals whose red cells lack GPA and GPB ([M.sup.k][M.sup.k] genotype) are resistant to invasion by Plasmodium.
Some merozoites enter neutrophils or monocytes and develop into gametocytes.
During intrahepatic or pre-erythrocytic merogony, the swollen infected liver cells eventually burst, discharging motile merozoites into the bloodstream.
They form preerythrocytic schizonts and multiply by schizogony, culminating in the production of 8-24 first generation merozoites that are released into the blood when the liver schizonts burst open [8].
Merozoites ranging from 10,000 to 30,000 exit the schizont within 60 seconds of hepatocyte invasion by sporozoites [7].
It gets in to body as a sporozoites which passes to lever and then released in to blood stream as merozoites. The apical membrane antigen (AMA-1) is expressed at the apical surface of merozoites and sporozoites during infection, previously named immunogenic type 1 integral protein, plays an important role in hepatocyte and erythrocyte invasion (Hodder et al., 2001; Silvie et al., 2004).
In some scientists' article, they assessed the roles of PP5 of second-generation merozoites in Eimeria tenella in the anticoccidial activity of TEM and quantitative real-time PCR were used to monitor the ultrastructural changes of EtPP5.
In addition, most malarial parasites produced in red blood cells (merozoites) are asexual, and will die inside a mosquito if taken during feeding.
