Mature Entamoeba histolytica/Entamoeba dispar cysts have 4 nuclei that characteristically have centrally-located karyosomes and fine, uniformly distributed peripheral chromatin. Cysts usually measure 12 to 15 µm.
The Entamoeba coli cyst typically has two to four times more nuclei than cysts in E. histolytica.
