Distinct microbial compositions between young and old male mice. Principal coordinate analysis (PCoA) plots of (a) weighted UniFrac distance and (b) Bray Curtis distance were used to visualize microbial β-diversities. Significance was determined by permutational multivariate analysis of variance (PERMANOVA) with 999 permutations, (a, b) showing a significant microbial community shift between the young (red dots) and old (blue dots) mice. c α-diversity was measured by Simpson index. d Mean relative abundance of taxa at phylum level. e Firmicutes to Bacteroidetes (F/B) ratio was calculated. f Cladogram of Linear discriminant Effect Size (LEfSe) analysis. g At the genus level, 6 discriminant taxa were identified by LEfSe analysis. Mann Whitney U test was performed for (c–e). For (d), *P < 0.05, **P < 0.01. 3-month, n = 8; 24-month, n = 8
