schizont

 [skiz´ont]
the stage in the development of the malarial parasite following the trophozoite whose nucleus divides into many smaller nuclei.

schiz·ont

(skiz'ont),
A sporozoan trophozoite (vegetative form) that reproduces by schizogony, producing a varied number of daughter trophozoites or merozoites.
See also: meront, segmenter.
Synonym(s): agamont, segmenting body
[schizo- + G. ōn (ont-), a being]

schizont

/schiz·ont/ (skiz´ont) the multinucleate stage in the development of some members of the Sarcodina and some sporozoans during schizogony.

schizont

(skĭz′ŏnt′, skĭt′sŏnt′)
n.
An apicomplexan cell formed by schizogony.

schizont

[skitsənt]
Etymology: Gk, schizein + genein, to produce
1 reproduction by multiple fission.
2 the multinucleated cell stage during the asexual reproductive phase in the life cycle of a sporozoon, such as the malarial parasite Plasmodium. Also called agamont. Compare sporont. See also schizogony. schizogonic, schizogonous, adj.

schizont

A stage in the life-cycle of a sporozoan parasite, especially a malarial parasite. A schizont reproduces by SCHIZOGONY producing multiple trophozoites or merozoites.

schizont

the asexual reproductive stage in the development of the Eimeria spp. and in many other coccidians, e.g. Toxoplasma spp. in the cat, Cystoisospora, Hammondia, Frenkelia and Isospora spp., following the trophozoite whose nucleus divides into many smaller nuclei.

INSIDE LIVER CELLS Sporozoites change into a form called schizonts, which grow and divide into thousands of merozoites.
In 75% of these cases the parasites were in later stages showing many schizonts, while one-quarter showed earlier stages of rings and trophozoites (4) (Figures 6 and 7).
Thereafter these schizonts rupture, releasing merozoites into the blood stream, which then infect red blood cells.
The presence of Plasmodium falciparum schizonts in peripheral blood smear is a rare occurrence and usually a cause for concern.
