(here sporozoite of Eimerian type)
of Eimeria type attaches to the surface of an intestinal epithelial
(other motile stages are merozoites - with apical complex - and microgametes - with 'perforatorium (Scholtyseck)' ). We find content of micronems (see sporozoite) in the intercellular space.
The 'apical complex' is responsible for invasion of the host cell.
|Sporozoite enters the host cell. Cytoskeleton is disintegrated and the parasite forms a pocket in the cytoplasm of the host cell called the parasitophorous vacuole (pV). Content of the rhoptries(?) (dense granules) is discharged into the pV.|
has entered the host cell enclosed by the parasitophorous vacuole.
One refractile body will disappear and the sporozoite transforms into a trophozoite in which multiplication of nuclei will start.
Finaly merozoites of the first generation will develop by budding from a big multinucleate residual body.
