Small free-living amoebae belonging to the genus Acanthamoeba are the most
common amoebae found in the soil and the other various environments.
The life cycle of Acanthamoeba is divided into two stages: the trophozoite
and the cyst. The cyst of Acanthamoeba is characterized by a double walled
envelope(exocyst and endocyst).
