| entamoeba | A genus of ameboid protozoa characterised by the presence of beaded chromatin on the inner surface of the nuclear membrane. Its organisms are parasitic in invertebrates and vertebrates, including humans. (12 Dec 1998) |

| Entamoeba buccalis | Former name for Entamoeba gingivalis. (05 Mar 2000) |
| Entamoeba coli | Nonpathogenic species that occurs in the large intestine of man, other primates, dogs, and possibly pigs; often confused with Entamoeba histolytica, but distinguished by nuclear details and by the number of nuclei and the form of chromatoidals in the cyst. (05 Mar 2000) |
| Entamoeba gingivalis | A species found in the oral cavity of man, other primates, dogs, and cats; in man, it is frequently associated with poor oral hygiene and its resultant diseases. (05 Mar 2000) |
| Entamoeba hartmanni | Species found in the large intestine of man, other primates, and dogs; now considered to be a distinct strain or species that is nonpathogenic and smaller than Entamoeba histolytica but otherwise indistinguishable from it; formerly called the "small race" of Entamoeba histolytica. (05 Mar 2000) |
| entamoeba histolytica | A species of parasitic protozoa causing entamoebiasis and amebic dysentery (dysentery, amebic). Characteristics include a single nucleus containing a small central karyosome and peripheral chromatin that is finely and regularly beaded. (12 Dec 1998) |
| Entamoeba moshkovskii | A species of amoeba very similar to Entamoeba histolytica, probably not infective to man, but a cause of diagnostic difficulties since it has been recovered from human sewage and may be responsible for false-positive results in tests of sewage plant effluents.
