Beta diversity analysis of the 16S rRNA v3+v4 sequencing results of the gut microbiota of feces from various groups of mice. A. Community clustering analysis of OTUs in samples from various groups at the phylum level: analysis at the phylum level showed that the relative abundance of Firmicutes was significantly increased in the gut of group F compared with that in group P, while the relative abundance of Verrucomicrobia was significantly decreased compared with group F. B. Community clustering analysis of OTUs in samples from various groups at the genus level: analysis at the genus level showed that the relative abundance of uncultured_bacterium_f_Lachnospiraceae was significantly increased, while that of Akkermansia was significantly decreased in group F compared with that in group P. C. Community clustering analysis of OTUs in samples from various groups at the species level: analysis at the species level showed that the relative abundance of uncultured_bacterium_f_Lachnospiraceae was significantly increased, while that of uncultured_bacterium_g_Akkermans was significantly decreased in group F compared with that in group P. D. Beta diversity analysis of OTUs in samples from various groups based on unweighted UniFrac. Results revealed significant differences in community distribution between the microbial communities of the three groups.
