BSAP targets surface molecules critical for gut colonization. Data represent results of gnotobiotic mouse competitive gut colonization assays. (A) Bf9343 versus Bf9343Δ1563. (B) Bu8492 versus Bu8492Δ00969 (Bu8492ΔO-ag). Means and standard errors of the results of 2 separate trials of 3 mice each are graphed for each strain. Across both trials, the wt/mutant ratios in the inoculum compared to the day 7 feces samples were significantly different: for Bf9343 versus Bf9343Δ1563, P = 2 × 10−6; for Bu8492 versus Bu8492Δ00969, P = 3 × 10−5.
