Bacterial Atlas of Mouse Gut Microbiota

Figure 2

The dominant bacteria and core bacteria in the gut microbiota of mice. (a) Principal coordinate analysis (PCoA) of the bacterial communities of mouse fecal samples. Each dot represented the stucture of gut microbiota of mice on day 3 (blue) or day 10 (red). There was no statistically significant difference of gut microbiota composition on day 3 and day 10 (). (b) Relative abundance of gut bacteria of mice. “Uncultured” represented the bacteria that could not be cultured. “Unclassified” indicated the sequences that could not be classified. “Norank” represented that there was no classification information or classification name. Bacteria with a relative abundance of less than 1% were classified as “Others.” (c) The core bacteria of mouse gut microbiota at the genus level. (d) The core bacteria of mouse gut microbiota at the species level. “Uncultured” represented the bacteria that could not be cultured.
