Fig. 3. The gut microbiota in asymptomatic Western populations as inferred by MetaPhlAn on 224 samples combining the HMP and MetaHIT cohorts.

Fig. 3

a) A taxonomic cladogram reporting all clades present in one or both cohorts (≥0.5% abundance in ≥1 sample). Circle size is proportional to the log of average abundance; color represents relative enrichment of the most abundant taxa (≥1% average in ≥1 cohort) between the HMP (139) and MetaHIT (85, healthy only) populations. b–c) Genus- (b) and species-level (c) taxonomic profiles of the most abundant clades hierarchically clustered (average linkage) with the Bray-Curtis similarity reveal sets of samples with similar microbial community compositions. With the exception of the cluster dominated by genus Bacteroides (B. vulgatus and B. ovatus in particular), samples from both studies are present in all groups, confirming substantial consistency of the gut microbiota characterized by independent and geographically distant western-diet asymptomatic cohorts. Only species and genera with at least 7.5% abundances at the 95th percentile of their distribution are reported.
