Figure 2. Dietary sialyllactose shifts the beta diversity of the murine colonic microbiota community structure.

Figure 2

The main effects of diet on microbial community composition were assessed using sequence data collapsed across stressor-exposed and non-stressed control mice. (A) A 3D PCoA plot using unweighted UniFrac distances showed that control diet clustered separately from 6′SL or 3′SL (p<.05). Dichotomous microbiota community structure clustering using unweighted UniFrac 2D PCoA plots was also performed. Microbial communities in mice fed a control diet were significantly different than communities in mice fed 6′SL (B; p<.05) or fed 3′SL (C; p<.05). Community structure did not differ in mice fed 6′SL or 3′SL (D). Significance testing was calculated using adonis, implemented in QIIME. n=16 control diet, n=14 3′SL, n=17 6′SL.
