Alterations of the Murine Gut Microbiome with Age and Allergic Airway Disease

Figure 4

Nonmetric multidimensional scaling (NMDS) of bacterial communities. Saline mice (young: dark blue and old: light blue) and HDM mice (young: red and old: pink) are shown. Both age () and HDM exposure () significantly influenced community structure based on permutational ANOVA analysis. Ellipses represent the 95% confidence interval on standard errors of means.
