Relative abundances of the top phyla were assessed in (A) control diet, (B) 6′SL, and (C) 3′SL fed mice. Bars represent means ± SEM. * indicates a significant difference between non-stressed and stressed animals within each bacterial phyla (p<0.05). Control diet: n=8 HCC Control, n=8 SDR Stressor. 6′SL: n= 7 HCC Control, n=7 SDR Stressor. 3′SL: n= 9 HCC Control, n=8 SDR Stressor.
