Acanthamoeba is a free-living ameba that is found throughout the world and that causes encephalitis, keratitis, and cutaneous infections in humans. It has two stages in its life cycle: a trophic stage and a resistant cyst stage. We describe here the ability of Acanthamoeba cysts to survive desiccation for more than 20 years.
