Description and Characteristics of Entamoeba gingivalis
- Recognizable through its dense core formed by a central point encircled by a circular halo
- Found in the mouth, specifically in the gingival pocket biofilm near the base of the teeth and in periodontal pockets
- Found in 95% of people with gum disease and rarely in people with healthy gums
- Transmission is direct from one person to another by kissing or sharing eating utensils
- Trophozoites are formed, with sizes ranging from 20 micrometers to 150 micrometers in diameter
- Have pseudopodia that allow them to move quickly
- Phagocytize the nucleus of polynuclear neutrophils by exonucleophagy in periodontal disease
- Spheroid nucleus is 2 micrometers to 4 micrometers in diameter and contains a small central endosome
- Numerous food vacuoles consisting mostly of phagocytised PMN nucleus, blood cells, and bacteria
- Can cause pyorrhoea
Feeding Behavior of Entamoeba gingivalis
- Main activity in infected periodontal crevices is feeding on the nucleus of white blood cells
- Penetrates into the cytoplasm to reach the nucleus and suctions its contents via negative pressure of the pseudopod
- Digests the food inside the endoplasm
- Phagocytosis can continue for more than 20 polynuclear neutrophil nuclei
- Leaves denucleated cells that release PMN-uncontrolled proteolytic enzymes on surrounding tissues
