Entamoeba gingivalis is an opportunistic Amoebozoa [ citation needed ] reported by some to cause disease [2] [3] [4] and is the first amoeba in humans to be described. It is found in the mouth [5] inside the gingival pocket biofilm near the base ggingivalis the teeth, and in periodontal pockets.

Only the trophozoites are formed and the size is usually 20 micrometers to micrometers in diameter. Entamoeba gingivalis have pseudopodia that allow them to move quickly and phagocytise the nucleus of polynuclear neutrophils by exonucleophagy in periodontal disease.


There are numerous food vacuoleswhich consists mostly of phagocitised PMN nucleus, blood cells and bacteria. The main activity of the amoeba Entamoeba gingivalis in the infected periodontal crevices, besides moving, consists in feeding on the nucleus of white blood cells.

The amoeba penetrates into the cytoplasm to reach the nucleus and literally suctions its contents via the negative pressure of the pseudopod. The food so gulped down is gradually digested inside the endoplasm. Phagocytosis can sometimes continue for more than 20 polynuclear neutrophil nuclei.

This activity leaves a denucleated cell, unable to achieve either its NETS activity or its preprogrammed apoptosis. It will release PMN-uncontrolled proteolytic enzymes on surrounding tissues and could be considered a pathogen from this vampirising activity.
