B–D Bacteria that were different among the groups in the B Coverage, C Shannon index and D Chao index. Differences were assessed by the Wilcoxon rank-sum test. ^*P < 0.05, ^**P < 0.01. E Hierarchical clustering tree at the operational taxonomic unit (OTU) level. F Principal co-ordinate analysis (PCoA) at the OTU level. G Circos sample—species relation map. H Community heatmap analysis at the genus level. I Community barplot analysis
