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.

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.
