  1. *Means significantly different (P?<?0.05) from CR within a metabolite and period using the Kruskal-Wallis pairwise comparison.
  2. Reported are mean values (days 24 of N-15 challenge periods)-SD and ratios are given as percentage of total SCFA (acetate, propionate, butyrate).
  3. N-15: S. Typhimurium N-15 without pro- or prebiotic; RBL67: B. thermophilum RBL67 alone; FOS: FOS alone; R-FOS: B. thermophilum RBL67?+?FOS; GOS: GOS alone; R-GOS: B. thermophilum RBL67?+?GOS; R-MOS: B. thermophilum RBL67?+?MOS.
