- Their presence in stool can be an indicator of fecal contamination of a food or water source, and does not rule-out the presence of other parasites. Entamoeba gingivalis is also considered nonpathogenic, but is found in about 95% of patients with gum disease and about 50% of patients with healthy gums.

Entamoeba gingivalis from aggressive periodontal disease patient biofilm using phase contrast microscope 1000x. It is recognizable through its dense core in the middle, formed by a central point encircled by a circular halo and surrounded by bigger phagosomes inside a greyish cytoplasm.
Entamoeba gingivalis (Fig. 4-5) is cosmopolitan in distribution, commonly found in the tartar and debris associated with the gingival tissues of the mouth. It was the first parasitic amoeba reported in humans (Gros, 1849).
