The presence of E. coli gadAB is associated with increased numbers of bacteria at the apical surface of intestinal epithelial cells in vivo. (A) Numbers of apical epithelial cell-associated bacteria in 18 ×20-magnification fields of intestinal tissue per IL-10−/− mouse monoassociated with NC101 or NC101ΔgadAB. (B) Relative numbers of E. coli 16S DNA copies in washed cecal tissue from the same IL-10−/− mice used for the experiment whose results are shown in panel A. Results are normalized to the level of tissue GAPDH expression. Data are presented as the mean ± SEM (n = 5 mice per group). *, P < 0.05 relative to NC101ΔgadAB-monoassociated mice; **, P < 0.01 relative to NC101ΔgadAB-monoassociated mice.
