The composition of intestinal microbiota. The relative contributions of dominant (a) phyla and (b) families (individual samples are shown in the left panels and pooled samples are shown in the right panels) and (c) the Firmicutes to Bacteroidetes ratio are shown as identified from pyrosequencing data. d Hierarchical clustering of gut microbial gene expression profiles. The distances between microbial communities from each sample are represented as an Unweighted Pair Group Method with Arithmetic Mean (UPGMA) clustering tree describing the dissimilarity between multiple samples. All values are indicated as the mean ± standard error of the mean (n = 4). *, p < 0.05 in comparison with young mice. YM, young mice; AM, aged mice
