H. pylori infection increased prevalence rate and colonization levels of SFB in the cecum and colon of Tac mice, respectively. (A) Fecal SFB levels were significantly decreased 2 weeks post H. pylori infection and then gradually went lower form 4 to 16 WPI. (B) Colonization dynamics of SFB over ileum, cecum, colon and feces with and without H. pylori infection. The numbers on the y axis represent the SFB 16S rRNA gene copies of which are expressed per µg murine DNA in the corresponding samples. P values: *<0.05. **<0.01, ***<0.001.
