Trophozoite stage of Entamoeba histolytica
Trophozoite stage of Entamoeba histolytica
The active, feeding stage of Entamoeba histolytica, characterized by pseudopodia for movement, a nucleus with a karyosome, and a vacuole containing ingested red blood cells (REC).
Cyst stage of Entamoeba histolytica
Cyst stage of Entamoeba histolytica
The stage of Entamoeba histolytica that is resistant to harsh environments, allowing transmission outside the host.
