“…Other common intestinal inhabitants with a worldwide distribution are Entamoeba species, the majority of which are generally accepted as commensal organisms [ 83 ]. Currently, eight species have been identified that are able to infect humans: E. histolytica , E. bangladeshi , E. dispar , E. hartmanni , E. moshkovskii , E. coli , and E. polecki , with E. histolytica as the only one with well-established pathogenicity [ 84 ]. The worldwide frequency of Entamoeba occurrence in humans is estimated at 3.5%.…”

“…However, the prevalence of commensal Entamoeba spp. has largely been underestimated due to high morphological and genetic similarity with the invasive E. histolytica [ 83 , 84 ]. Microscopy, the most widely used method for the detection of Entamoeba organisms, is not always sufficient for differentiating between the invasive E. histolytica and non-pathogenic strains of Entamoeba [ 85 ].…”

The human gastrointestinal microbiota contains a diverse consortium of microbes, including bacteria, protozoa, viruses, and fungi. Through millennia of co-evolution, the host–microbiota interactions have shaped the immune system to both tolerate and maintain the symbiotic relationship with commensal microbiota, while exerting protective responses against invading pathogens. Microbiome research is dominated by studies describing the impact of prokaryotic bacteria on gut immunity with a limited understanding of their relationship with other integral microbiota constituents. However, converging evidence shows that eukaryotic organisms, such as commensal protozoa, can play an important role in modulating intestinal immune responses as well as influencing the overall health of the host. The presence of several protozoa species has recently been shown to be a common occurrence in healthy populations worldwide, suggesting that many of these are commensals rather than invading pathogens. This review aims to discuss the most recent, conflicting findings regarding the role of intestinal protozoa in gut homeostasis, interactions between intestinal protozoa and the bacterial microbiota, as well as potential immunological consequences of protozoa colonization.

“…More recent in their study showed that Entamoeba gingivalis can damage periodontal tissues [9]. Entamoeba parasites have at minimum 7 species (E.histolytica, E.dispar, E.moshkovskii, E.coli, E.polecki E.hartmann, E.gingivalis) [10]. These parasites are parasitic single-celled organisms.…”

The oral cavity is environment to a diverse range of organisms that make up an essential element of the human microbiota. There are 50-1000 kinds of microorganisms capable of colonizing the mouth. The entamoeba parasites have at minimum 7 species (E. histolytica, E. dispar, E. moshkovskii, E. coli, E. polecki E. hartmann, E. gingivalis). These parasites are parasitic single-celled organisms and Entamoeba gingivalis was the first amoeba to be described in 1849 that was capable of existing in humans. It was shown that only Entamoeba gingivalis is able to colonize the oral cavity. The aim of this study was to evaluate prevalence of E. Gingivalis in periodontal disease using two electronic database search engines. In order to have a broader view of the subject, a comprehensive manual search was conducted on these content aggregators and the initial search resulted in 277 articles using the keywords „Entamoeba gingivalis”, „periodontitis”, „E. gingivalis”, „periodontal disease”, „prevalence”, and „incidence”, in different combinations. The results showed that 755 cases were infected with Entamoeba gingivalis out of a total number of 1,729 patients diagnosed with periodontal disease indicating a global prevalence of 43%. When comparing different stages of periodontal diseases results revealed that the prevalence in patients with gingivitis was 58% while in periodontitis group the prevalence was 44%. Overall prevalence of Entamoeba Gingivalis based on gender was 43 % in female patients whilst in male patients was 47%. Based on the results it can be concluded that the higher incidence of Entamoeba Gingivalis in people with periodontal disease compared to healthy people is more than just a sign of the disease; it may also be linked to the severity of the condition and its propensity to progress.

“…The hallmark of amoebiasis is profound tissue destruction, which results in massive intestinal ulceration and even fatal extraintestinal abscesses. It has been estimated that 50 million people suffer from invasive amoebiasis worldwide, causing approximately 100,000 deaths annually ( 1 – 4 ). The adherence of E. histolytica trophozoites to colonic mucins and epithelial cells is the initial event of colonization and invasion and is an indispensable prerequisite for amoebic cytotoxicity ( 5 ).…”
