, n=34. Principal coordinate analysis plot using Bray-Curtis distance of bacterial relative abundance on the genus level as distance metric. Symbols are samples, with shape / colour indicating assigned enterotype . All genera with an average relative abundance of 0.1% or more were plotted as supplementary variables . OTUs that could not be assigned up to the genus level were assigned to a dummy “genus” labelled with the most specific classification available for that OTUs.
To evaluate the robustness of the observed differences between enterotypes, individuals for whom the assignment to an enterotype was ambiguous plot or in between more densely populated regions) were excluded . The PCoA plot was generated using Bray-Curtis distance of bacterial relative abundance on the genus level as distance metric. Symbols are samples, with shape / colour indicating assigned enterotype , n=21; yellow diamonds:, n=21; grey dots: unclassified, n=28).
