Comparison of the gut microbiota between the native Tibetans and the Chinese Hans at the phylum and genus levels. (a) Wilcoxon rank-sum analysis showing the significantly different gut microbiota phyla between the native Tibetans and the Hans. , , and . (b) Heat map showing the most relatively abundant 50 genera of the gut microbiota of both the native Tibetans and the Hans. Sample ID 0-13: samples of Hans; sample ID 3_1-3_15: samples of native Tibetans. (c) Principal component analysis (PCA) showing differences in the gut microbiota between the native Tibetans and the Hans based on the composition of the bacterial communities. (d) Principal coordinate analysis (PCoA) of the differences in the gut microbiota between the native Tibetans and the Hans based on the distance matrix of Bray-Curtis dissimilarity of the microbial community.
