Effect of MUC4 polymorphism on the percentage of animals with different levels of ETEC F4 counts in colon content on days 4 and 8 post-inoculation (PI). Different animals were sampled on days 4 and 8 post-inoculation (PI). 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). Values of p were obtained using Fisher’s exact test in R software. a and b indicate statistically significant differences between groups. MUC4+, Mucin 4 susceptible genotype; MUC4−, Mucin 4 resistant genotype; PI, post-inoculation.
