Entamoeba coli has a worldwide distribution and is one of the most commonly reported Entamoeba species in clinical specimens. Non-human primates may serve as reservoir hosts. Trophozoites of E. coli measure 15–50 μm and have a single nucleus with irregular peripheral chromatin and a usually eccentric karyosome.
Entamoeba hartmanni, also in the quadrinucleate cyst clade, is much smaller than E. histolytica with cysts reaching only 10 μm in diameter and trophozoites of 3–12 μm in diameter. The larger cysts of E. coli may possess as many as eight nuclei and can be identified by splinter-like chromatid bodies in their cytoplasm.
