Key: Log10 CFU (colony forming unit) given per gram of wet weight of feces or wet weight of jejunal content. Data are presented as mean±s.d. The average values obtained from the HBM+probiotics mice supplemented with prebiotics were compared with corresponding HBM+probiotics control mice, *, ** and *** designate significant difference at 95, 99 and 99.9% confidence level, respectively; —, probiotics not present in the gut microbiota.
