Figure 5. Microbiota composition in stomach, cecum, and colon of H pylori-infected male INS-GAS mice (n = 3, 15 weeks postinfection) vs. uninfected controls (n = 2). Note the significant increase in the relative abundance of Firmicutes and decrease of Bacteroidetes in the stomachs of H pylori–infected INS-GAS mice (p < 0.05), whereas no significant changes were observed in the colon and ceca of H. pylori-infected mice.
