Quantification of the inner mucus layer thickness in antibiotic withdrawal experiments. The thickness of the inner mucus layer in all regions of the colon returned to control levels (C) in antibiotic-treated mice following a 7-day recovery period (ANOVA, P > 0.05 in all colonic parts). No significant difference was found among treatment groups and controls. The symbols LR, MR, and HR represent groups of mice that recovered from 0.5 g streptomycin-bacitracin, 1 g streptomycin-bacitracin, and 1.5 g streptomycin-bacitracin treatment, respectively
