Relative expression (fold change) of claudin-1 (A,B) and occludin (C,D) mRNA in the ileum (A,C) and colon (B,D) of the gnotobiotic piglets: germ-free (GF), infected with S. Typhimurium LT2 for 24 h (LT2), associated with B. animalis subsp. lactis BB-12 (BB12), and associated with BB12 and infected with LT2 for 24 h (BB12 + LT2). The values are presented as mean + SEM. Statistical differences were calculated by one-way ANOVA with Tukey’s multiple comparison post hoc test, and p-values < 0.05 are denoted with different letters above the columns. Six samples in each group were analyzed.
