sporozoite /spo·ro·zo·ite/ (-zo´īt) the motile, infective stage of certain protozoa that results from sporogony.
sporozoite
sporozoite [spor″o-zo´īt]
spo·ro·zo·ite (spôr  -z   t)n. Any of the minute undeveloped sporozoans produced by multiple fission of a zygote or spore, especially at the stage just before it infects a new host cell. |
sporozoite
[spôr′əzō′īt]
Etymology: Gk, sporos + zoon, animal
any of the cells resulting from the sexual union of spores during the life cycle of a sporozoon. It refers specifically to the elongated nucleated cells produced by the multiple fission of the zygote contained in the oocyst in the female Anopheles mosquito during the sexual reproductive stage of the life cycle of the malarial parasite Plasmodium. On release from the oocyst, the sporozoites migrate to the salivary glands of the mosquito, where they are transmitted to humans and develop within the parenchymal cells of the liver as merozoites. Also called falciform body. See also malaria, Plasmodium.
sporozoite [spor″o-zo´īt]
a spore formed after fertilization; any one of the sickle-shaped nucleated germs formed by division of the protoplasm of a spore of a sporozoan organism. In malaria, the sporozoites are the forms of the plasmodium that are liberated from the oocysts in the mosquito, that accumulate in the salivary glands, and that are transferred to humans when the mosquito feeds.
sporozoite
a spore formed after fertilization; a sickle-shaped nucleated germ formed by division of the protoplasm during sporogony (asexual replication) of an apicomplexan parasite. The sporozoite is an infective stage (e.g. Eimeria, Cryptosporidium).
