Overview of the fecal bacterial microbiome from sequencing at WEHI (A,B,C) or BCM (D,E,F). (A,D) Dominant bacterial genera in fecal samples, or higher taxa where genus was not available. Bars are colour-coded by phyla: red Bacteroidetes, blue Firmicutes, green Proteobacteria, brown Actinobacteria, yellow Verrucomicrobia. (B,E) Alpha diversity within samples. Two measures are shown: observed number of OTUs per sample, an estimate of richness, and Inverse-Simpson index indicating the evenness of the sample. Samples were sub-sampled to the smallest sample size, and values are the mean of 10 random sub-samples. Boxes show the inter-quartile range for the four methods on three days. (C,F) Beta diversity. NMDS ordination of the UniFrac distance between samples, a representation of phylogenetic similarity.
