Apicomplexan Life Cycle

Infectious Stages:

Sporozoite
(sporos, seed + zōon, animal) is the cell form that infects new hosts.

Merozoite
(meros, part [of a series] + zōon, animal) is the result of merogony that takes place within a host cell. During this stage, the parasite infects the host's cells and then replicates its own nucleus and induces cell segmentation in a form of asexual reproduction.

Gametocyte
(gametēs, partner + kytos, cell) is a name given to a parasite's gamete-forming cells.

Ookinete
(ōon, egg + kinētos, motile) is a fertilised zygote capable of moving spontaneously.

Trophozoite
(trophē, nourishment + zōon, animal) is the activated, intracellular feeding stage in the apicomplexan life cycle.

Hypnozoite
(hypnos, sleep + zōon, animal) is a quiescent parasite stage that is best known for its probable association with latency and relapse in human malarial infections.

Bradyzoite
(bradys, slow + zōon, animal) is a sessile, slow-growing form of zoonotic microorganisms.

Tachyzoite
(tachys, fast + zōon, animal), contrasting with a bradyzoite, is a form typified by rapid growth and replication.

Oocyst
(ōon, egg + kystis, bladder) is a hardy, thick-walled spore, able to survive for lengthy periods outside a host.
