Gastric and Duodenum Microflora Analysis After Long-Term Helicobacter pylori Infection in Mongolian Gerbils

Abstract

Long-term H. pylori colonization affected the distribution and numbers of indigenous microflora in stomach and duodenum. Successful colonization caused a more severe gastritis. Gastric microenvironment may be unfit for lactobacilli fertility after long-term H. pylori infection, while enterococci, S. aureus, bifidobacteria, and bacteroides showed their adaptations.
