Sporozoa

Sporozoa , phylum of unicellular heterotrophic organisms of the kingdom Protista . Unlike most other protozoans , sporozoans have no cilia or flagella. All species are parasitic and have elaborate life cycles, often requiring more than one host. The best-known sporozoan is Plasmodium falciparum, the causative organism of malaria .

Sporozoa (phylum Protozoa) A subphylum of protozoa in which the life cycle includes a spore-forming or cyst-forming stage. Asexual reproduction occurs by multiple fission. All members are parasitic, parasitizing hosts throughout the animal kingdom. Some species can cause important diseases.

Apicomplexa (Sporozoa) A phylum of parasitic protoctists (see also protozoa) whose members may have a number of different animal hosts. Their complex life cycle involves the alternation of asexual reproduction (multiple fission) and sexual reproduction and the production of resistant spores (see illustration). The phylum includes the agents causing malaria (Plasmodium) and toxoplasmosis (Toxoplasma).
