Extended Data Fig. 7: Microbiota alterations upon Antibiotics (Abx) and HFD treatments.

Three-week-old C57BL/6 J male mice were administrated with free antibiotics or ampicillin (20 mg kg−1) and vancomycin (20 mg kg−1)-loaded nanoparticles for 5 successive days. Control mice had no antibiotics exposure. All mice were treated with HFD from age of 7 weeks. Fecal pellets were collected on the day end of the HFD treatment for 16S rRNA sequencing. a, The observed species number of gut microbiota. b, PCA plot generated from unweighted UniFrac distance matrix displaying the distinct clustering pattern of gut microbiota. c, Relative abundances of the gut commensal microorganisms at the family level. n = 5 mice. All values are expressed as the mean ± s.e.m. Statistical significance was determined using one-way ANOVA with Tukey’s multiple comparisons test in a. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
