Prospects for elucidating the phylogeny of the apicomplexa

All members of this phylum have an infectious stage—the sporozoite—which possesses three distinct structures in an apical complex.

The tick injects sporozoites into the blood stream upon feeding; these ‘zoites directly invade the erythrocyte and undergo asexual replication (binary fission) to produce many merozoites that are released into the circulation following erythrocyte rupture and then reinvade erythrocytes, and the cycle continues.The Apicomplexa is the only large taxonomic group whose members are entirely parasitic and is, therefore, presumably of major interest to parasitologists.We might, for example, expect that we know a great deal about the biology of the group by now and that we have a clear phylogenetic framework within which to organize that knowledge.The Apicomplexa (also called Apicomplexia) are a large phylum of parasitic alveolates.Most of them possess a unique form of organelle that comprises a type of plastid called an apicoplast, and an apical complex structure.
