Entamoeba gingivalis is commonly found in swab samples taken from the gingival crevices of our mouths. E. gingivalis does not form cysts, and therefore, transmission is probably through kissing or sharing food and eating implements. There are occasional case reports of the recovery of E. gingivalis from the vagina (Bradbury et al. 2019) and the lungs (Jian et al. 2008). Although often implicated in periodontitis (an inflammatory disease that affects the gums and the bone surrounding the teeth), it infects both healthy and diseased individuals (Bonner et al. 2018). Part of the problem in determining its association with disease is the wide variation of rates of recovery of E. gingivalis from samples. This is probably owing to the collection techniques employed, and the recommendation is to take 5–10 samples from each person.
