Figure 2. Effect of whole grains on the fecal microbiota in relation to bacterial taxa linked to enterotypes. Impact of dietary treatments on the abundance of Bacteroides based on whether the subject harbored (A) the enterotype dominated by Bacteroides or (B) the other non-Bacteroides two enterotypes (Ruminococcus and Prevotella) at baseline. The abundance of the genera (C)Bacteroides and (D)Prevotella in fecal samples of all subjects throughout the treatments. Dots represent populations within individual fecal samples, color-coded according to enterotypes (green = Bacteroides-dominant, red = Ruminococcus-dominant, yellow = Prevotella-dominant). Samples of subjects that showed changes in enterotype identity are linked with lines.
