Laboratory Diagnosis. Identification of E. gingivalis is usually made by the finding of trophozoites in scrapings of the gums and teeth; trophozoites may be seen ingesting white cells and epithelial cell nuclei. Two genetic sub types exist, the ST1 and ST2-kamaktli subtypes, though any clinical significance or morphologic differences between ...
May 19, 2021 · In those with no periodontal disease, ST1 was 1.64 x more prevalent than ST2 and was found in 48.6% of the individuals. In that study, nested PCR was used for detection, and this diagnostic approach might provide an even higher sensitivity than that of the single-round PCR used in the present study.

Jul 10, 2020 · Researchers at Charité — Universitätsmedizin Berlin have identified the amoeba, Entamoeba gingivalis, is similar to that of the parasite, Entamoeba histolytica, which is responsible for invading gingival tissue and feeding on cells to cause tissue destruction.
Entamoeba gingivalis is an opportunistic Amoebozoa [citation needed] (reported by some as an effect of disease; not a cause [hence status as a commensal]) [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 of the teeth, and in periodontal pockets. [1]

Apr 1, 2021 · Go to: Abstract. The protozoan Entamoeba gingivalis colonizes the healthy oral mucosa with a prevalence of 15%. Colonization can be asymptomatic, and it is considered not pathogenic. However, it is able to invade lacerated oral mucosa, where it ingests fragments of live cells, suggesting pathogenous potential.

Diagnosis of E. gingivalis infection is made by microscopic examination of tooth and gum scrapings stained with routine microbiologic stains (e.g. Wheatley's trichrome stain), or rarely, tissue biopsies stained with hematoxylin and eosin (H&E), periodic acid-Schiff (PAS) and Masson's trichrome ( Bhaijee and Bell, 2011 ).
Oct 29, 2018 · Consensual treatment in clinics is thus based on the mechanical and/or surgical removal of dental plaque, calculi, and damaged/inflamed tissues (Smiley et al., 2015). These paths lead to an inefficient solution dealing with late symptoms without considering the evoked causes of the disease.
