Results

UniFrac distance analysis results showed a significant change in the gut microbiome composition of synbiotics group in comparison with that of placebo group. During the intervention period in synbiotics group, there was an increase in the abundance ratio of genus Bifidobacterium and Anaerostipes and a decrease in genus Clostridium.
The quantitative PCR results showed that the total number of fecal Bifidobacterium significantly increased in only synbiotics group during the intervention period.
