Abstract

Owing to its strong acid production, the stomach was known to be a bacteria-free organ for many years. On the other hand, the presence of Helicobacter pylori (H. pylori) and other acid-resistant microbiota that are to persist in the stomach challenged this. It is now recognized that the existence of H. pylori and non-H. pylori species have been linked to the improvement of gastric disease; despite this, there is little published data on the interaction of gastric bacterial flora and the resultant effect on gastric health. The stomach has a unique microbiota including five major phyla, such as Firmicutes, Proteobacteria, Actinobacteria, Fusobacteria and Bacteroidetes. These phyla are identified in both H. pylori-infected and uninfected persons. The resident gastric microflora may mediate the role of H. pylori in the gastric diseases. This article aims to review previous studies that examine the impact of H. pylori infection and the effect of resident gastric microbiota on gut health and disease conditions.

幽门螺杆菌感染与胃微生物群
由于胃酸分泌旺盛,多年来人们一直认为胃是无菌器官。另一方面,幽门螺杆菌(H. pylori)和其他耐酸微生物群在胃中的存在对这一观点提出了挑战。现在人们已经认识到,幽门螺杆菌和非幽门螺杆菌的存在与胃病的改善有关;尽管如此,关于胃细菌菌群的相互作用及其对胃健康的影响的公开数据却很少。胃中有独特的微生物群,包括五大菌门,如坚固菌门、变形菌门、放线菌门、镰刀菌门和类杆菌门。感染幽门螺杆菌和未感染幽门螺杆菌的人体内都能发现这些菌群。常住胃微生物区系可能是幽门螺杆菌在胃病中发挥作用的媒介。本文旨在回顾以往研究幽门螺杆菌感染的影响以及常驻胃微生物群对肠道健康和疾病状况的影响:Ozbey G, Sproston E, Hanafiah A. 幽门螺杆菌感染与胃微生物群。Euroasian J Hepato-Gastroenterol 2020;10(1):36-41.
