Abstract

Cysts are typically resting, dormant and/or resistant stages in the full life cycle of many protozoan species, sometimes playing a role in dispersal of the organism. Spores are a stage commonly associated with multiplication and propagation of a protozoan organism, sometimes having a resistant wall and often, in parasitic forms, serving as an obligate stage in the life cycle.
