Goblet cells density in the colon of gnotobiotic piglets: Germ-free (GF; (A)), colonized with B. boum RP36 (RP36; (B)), colonized with B. boum RP37 (RP37; (C)), infected with S. Typhimurium LT2 (LT2; (D)), colonized with RP36 and infected with LT2 (RP36+LT2; (E)), and colonized with RP37 and infected with LT2 (RP37+LT2; (F)). Bars represent 500 µm. The goblet cell counts (G) 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.
