trophozoite

 [trof″o-zo´īt]
the active, motile feeding stage of a sporozoan parasite.

troph·o·zo·ite

(trof'ō-zō'īt),
The ameboid, vegetative, asexual form of certain Sporozoea, such as the schizont of the plasmodia of malaria and related parasites.
[tropho- + G. zōon, animal]

trophozoite

/tropho·zo·ite/ (-zo´īt) the active, motile feeding stage of a sporozoan parasite.

trophozoite

(trō′fə-zō′īt′)
n.
An elongated cell that develops from a sporozoite or a merozoite of an apicomplexan parasite and that feeds and grows within the host.

trophozoite

[trof′əzō′īt]
Etymology: Gk, trophe + zoon, animal
an immature ameboid protozoon. Diseases in which trophozoites may be isolated by bacteriological studies include amebic dysentery, malaria, and trichomonas vaginitis. When fully developed, a trophozoite may be identified as a schizont.

trophozoite

The active growing stage of a protozoan parasite, as distinct from the dormant encysted stage. In the malarial parasite, the asexual, vegetative stage before the development of the mature schizont.

trophozoite

the form of a protozoan of the class Sporozoa in the feeding stage, containing SPOROZOITES. In the MALARIA PARASITE this stage occurs in the human red blood cell.

Trophozoite
