merozoite

 [mer″o-zo´īt]
one of the organisms formed by multiple fission (schizogony) of a sporozoite within the body of the host.

mer·o·zo·ite

(mer'ō-zō'īt),
The motile infective stage of sporozoan protozoa that results from schizogony or a similar type of asexual reproduction; for example, endodyogeny or endopolygeny. Merozoites form at the surface of schizonts, blastophores, or invaginations into schizonts, and are responsible for the vast reproductive powers of sporozoan parasites; this is seen in human malaria, where the cyclic production of merozoites produces the typical fever and chill syndrome.

merozoite

(mĕr′ə-zō′īt)
n.
Any of the cells of an apicomplexan parasite that arise following multiple asexual fission and may enter either the asexual or sexual phase of the life cycle.

merozoite

[mer′əzō′īt]
Etymology: Gk, meros + zoon, animal
an organism produced from segmentation of a schizont during the asexual reproductive phase of the life cycle of a sporozoon, specifically the malarial parasite Plasmodium. Merozoites can either continue the asexual phase of the life cycle by developing into trophozoites and repeating the process of schizogony or differentiate into male and female gametes and enter the sexual stage. See also Plasmodium.

merozoite

A motile, pre- and extra-erythrocytic form of a sporozoan (e.g., plasmodia), resulting from the asexual division of a schizont during shizogony, which in Plasmodium spp occurs in the liver or red cells. Merozoites either infect other red cells or spontaneously develop into sexual forms—i.e., microgametes (male forms) or macrogametes (female forms).

The motile infective stage of sporozoan protozoa that results from schizogony or a similar type of asexual reproduction; responsible for the vast reproductive powers of sporozoan parasites.
[mero- + G. zōon, animal]

merozoite

One of the stages in the life cycle of the malarial parasite. Merozoites are small motile bodies released in large numbers after asexual division of the schizont in red blood cells. They invade further red cells or liver cells where they continue to reproduce asexually or initiate a sexual reproduction cycle by the formation of male and female sex cells.

Three of the antigens, circumsporozoite protein (CSP), liver stage antigen-1 (LSA1), and antigen 2 (Ag2) are expressed from a single adenovector and target the liver stage of the disease while two additional antigens, merozoite surface protein-1 (MSP1) and apical membrane antigen-1 (AMA1), are expressed from a second adenovector and target the blood stage of the disease; all are thought to be important in preventing or limiting the severity of malaria.
