| Objective: To investigate the influence of Lactobacilli of the normal microbiota in the human stomach on the infection
of Helicobacter pylori（H. pylori) . Methods: A total of 51 specimens of gastric mucous were collected from gastritis patients undergoing
routine endoscopy. Lactobacilli were isolated using Rogosa Agra plates. The identification of species of the bacterium was conducted
using 16S rRNA gene sequencing. The degree and activity of gastritis were evaluated according to Sydney System. H. pylori detected
with Gimesa staining. Results: A total of 9 species of lactobacilli were isolated from the stomach. The prevalence of lactobacilli was 49.0
%. There were no significant differences in the H. pylori infection rate, the degree and activity of the inflammation between the
lactobacillus positive patients and lactobacillus negative patients (P> 0.05), however, H. pylori positive patients had a more severe
inflammation compared to HP-negative patients (P <0.05). There were no differences in the prevalence of H. Pylori infection between the
probiotic species of lactobacilli positive and negative patients (P> 0.05). Conclusion : It appeared that the presence of species of
lactobacilli in the stomach had no influence on the H. pylori infection. |
