Protozoa multiply sexually, asexually and can also use a combination of both, as seen in the coccidia class. Replication can be by binary or multiple fission. Different protozoa use different forms of motility, including flagella, cilia, pseudopodia and gliding.
*Most protozoal reproduction is asexual via binary fission, schizogony and sporogony
*Some protozoa also use sexual reproduction called gametogony
*In some species, sexual and asexual reproduction occurs in the same host, whilst in others asexual reproduction occurs in the vertebrate host and sexual reproduction in the arthropod vector
*Homoxenous
**Parasite uses a single host species during its life cycle (direct)
**E.g. ''[[Eimeria spp.|Eimeria]]''
*Heteroxenous
**Parasite uses more than one host during its life cycle (indirect)
**E.g. ''Trypanosomes''
*Facultatively heteroxenous
**Parasite '''may''' use more than one host during its life cycle but this is not essential
**E.g. ''Toxoplasma gondii''
