| − | 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''
