Role of Gastric Microorganisms Other than in the Development and Treatment of Gastric Diseases.

Biomed Res Int 2022 14;2022:6263423. Epub 2022 Mar 14.

Department of Gastroenterology, Affiliated Hospital of Inner Mongolia Medical University, Hohhot 010050, China.

The microenvironment in the stomach is different from other digestive tracts, mainly because of the secretion of gastric acid and digestive enzymes, bile reflux, special mucus barrier, gastric peristalsis, and so on, which all contribute to the formation of antibacterial environment. Microecological disorders can lead to gastric immune disorders or lead to the decrease of dominant bacteria and the increase of the abundance and virulence of pathogenic microorganisms and then promote the occurrence of diseases. The body performs its immune function through innate and adaptive immunity and maintains microbial balance through the mechanism of immune homeostasis. Read More
