(A) Schematic representation of the predominant phyla of the gastric microbiota based on H. pylori infection status. H. pylori-negative individuals harbor a microbiota that is more complex and highly diverse compared to H. pylori-positive individuals. (B) Schematic representation of the predominant genera at different stages within the gastric carcinogenesis cascade. Following infection with H. pylori, Proteobacteria and specifically H. pylori dominate the gastric microbiota. This leads to the development of chronic gastritis. In the later stages of the disease, ranging from intestinal metaplasia to gastric adenocarcinoma, a number of genera are enriched. These include Escherichia-Shigella and Burkholderia within the Proteobacteria phylum; Lactobacillus, Lachnospiraceae, Streptococcus, and Veillonella within the Firmicutes phylum; and Prevotella within the Bacteroidetes phylum.
