DEFINITION:
- Apicomplexa
-
A phylum of uninucleate, parasitic tissue-dwelling protozoa characterized by the presence of an apical complex; one or more micropores are generally present at some stage of development. Flagella and cilia are absent in the adult stage; many mature apicomplexans glide by means of ultrastructural ridges and fibers on the body surface. They typically reproduce asexually by means of multiple fission, forming merozoites or schizoites, or by endodyogeny, or sexually by syngamy. It comprises two classes: Perkinsea and Sporozoea. Called also Sporozoa.
