A, The abundance of the dominant bacteria in the duodenum communities at the phylum level. Each bar represents the abundance of the most abundant phyla in each group. Different colors represent different bacterial phyla. “Others” represents the sum of the abundance of all the phyla besides the top 10. B, Hierarchically clustered heatmap analysis showing the highly represented bacterial taxa (at the phylum level) in the three groups. The relative percentages (%) of the bacterial families are indicated by varying colors intensities according to the legend at the top of the figure.
