Medical Term:


Pronunciation: mer′ō-zō′īt

Definition: The motile infective stage of sporozoan protozoa that results from schizogony or a similar type of asexual reproduction; 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.

Synonym(s): endodyocyte2

[mero- + G. zōon, animal]
