Ampicillin-Improved Glucose Tolerance in Diet-Induced Obese C57BL/6NTac Mice Is Age Dependent

Figure 5

Principal component analysis (PCA) plots of the gut microbiota in diet-induced obese C57BL/6 mice treated or nontreated with Ampicillin from birth and until five weeks of age, from 12 to 16 weeks of age, or both. The clustering on all four PCA plots is significant: (a) PC1: 𝑃=0.000, PC2: 𝑃=0.001, (b) PC1: 𝑃=0.000, (c) PC1: 𝑃=0.000, PC3: 𝑃=0.05, (d) PC1: 𝑃=0.000.
