Comparison of microbiotas from non-malignant lung tissue and other human body sites (HMP 16S V3–V5 phase 1 data). a, b Principal coordinates analysis (PCoA) of Euclidean distance of phylum-level taxonomic profiles (a) and KEGG module functional profiles (b). The proportion of variance explained by each principal component is denoted in the corresponding axis label. c, d Phylum-level taxonomic profiles (c) and KEGG module functional profiles (d) by body site. The dendrogram shows similarity by body site based on the Euclidean distance of phylum-level/KEGG module profiles (average by body sites). Only phyla/modules with relative abundance >1 % are shown. Branch colors show different body sites (blue, oral, lung, and stool; black, nasal and skin; purple, vagina). “H” and “L” indicate that lung is significantly higher or lower, respectively, in relative abundance of the designated phylum/module compared with all the other body sites’ samples combined (P < 0.05 by Wilcoxon test with Bonferroni correction)
