Evolution of average fecal scores for the different experimental groups during the post-inoculation (PI) period. CTR+: non-inoculated animals receiving placebo; PRO−: inoculated animals receiving the probiotics; PRE−: inoculated animals receiving the prebiotic; SYN−: inoculated animals receiving the synbiotic; CTR−: inoculated animals receiving placebo. N = 6 for all groups except for non-challenged animals (N = 8). MUC4 represents the effect of polymorphism of the MUC4 gene. a,b, and c indicate statistically significant differences between groups. x and y indicate statistical trends among groups. Bars correspond to the standard error. PI, post-inoculation.
