It is well-known that microbiota dysbiosis is closely associated with numerous diseases in the human body. The oral cavity and gut are the two largest microbial habitats, playing a major role in microbiome-associated diseases. Even though the oral cavity and gut are continuous regions connected through the gastrointestinal tract, the oral and gut microbiome profiles are well-segregated due to the oral–gut barrier. However, the oral microbiota can translocate to the intestinal mucosa in conditions of the oral–gut barrier dysfunction. Inversely, the gut-to-oral microbial transmission occurs as well in inter- and intrapersonal manners. Recently, it has been reported that oral and gut microbiomes interdependently regulate physiological functions and pathological processes. Oral-to-gut and gut-to-oral microbial transmissions can shape and/or reshape the microbial ecosystem in both habitats, eventually modulating pathogenesis of disease. However, the oral–gut microbial interaction in pathogenesis has been underappreciated to date. Here, we will highlight the oral–gut microbiome crosstalk and its implications in the pathogenesis of the gastrointestinal disease and cancer. Better understanding the role of the oral–gut microbiome axis in pathogenesis will be advantageous for precise diagnosis/prognosis and effective treatment.

The variability inHelicobacter pylori vacAandcagAgenes has been related to the progression of the gastrointestinal disease; also the presence ofH. pyloriin the oral cavity has been associated with periodontal disease in adults, but, in children without dyspeptic symptoms, little is known about this. We evaluated the prevalence ofH. pyloriand the presence ofvacA/cagAgenotypes in the oral cavity of Mexican children without dyspeptic symptoms. The gingival status was measured, and dental plaque samples (n=100) were taken. 38% of children were positive forH. pylori16S rRNA gene by qPCR. A significant association betweenH. pylorioral infection and gingival status was observed (P<0.001). In 34.6% (9/26) of mild gingivitis cases,s1m2genotype was found, whiles1m1was typed in 50% (3/6) of moderate gingivitis. ThecagAprevalence amongH. pylori-positive children was 80.8% (21/26), 83.3% (5/6), and 16.7% (1/6) of cases of mild gingivitis, moderate gingivitis, and nongingivitis, respectively (P<0.001). Thes1m1/cagA+ combinational genotype was the most detected in children with gingivitis. Our results suggest that the prevalence ofH. pyloriand detection ofvacA/cagAgenotypes-associated gastrointestinal disease in the oral cavity could be related to the progression of gingivitis in asymptomatic children.
