Bacterial Atlas of Mouse Gut Microbiota

Figure 1

Bacterial communities in mice. (a) A flow diagram of the experiment. A total of 300 female and 300 male mice were fed sterilized water. Fecal samples were collected on day 3 and day 7 for bacteria 16S rRNA sequencing. At day 7, the blood and intestinal tissues of mice were subjected to the detection of physiological parameters. (b) Observation of microbes isolated from fecal samples of mice using transmission electron microscopy. The representative images were presented. Scale bar, 1 μm. (c) Rarefaction curves of the bacterial 16S rRNA genes of the feces of 600 mice. (d) Numbers of OTUs homologous to the known bacteria in mouse gut microbiomta at each classification level. (e) Pie diagram of the known and unknown OTUs in all samples at the genus level.
