The cysts typically measures 10 - 20 microns with 4 nuclei and rounded or cigar shaped chromatoidal bars. An immature cyst may have a vacuole and fewer nuclei. The only infective stage of E. histolytica is the mature cyst.
The trophozoite of E. histolytica possesses one nuclei with a fine even peripheral chromatin. The punctate karyosome is usually central but maybe off center. The cytoplasm usually contains little debris with a fine outer membrane. It usually measures from between 12 and 20 microns.
