Bacterial community composition analysis between samples with high (<i>n</i>=13) and low (<i>n</i>=13) FP activity.

Abstract

<p>Principal coordinates analysis (PCoA) plots of un-weighted and weighted UniFrac distances for samples with high (blue circles) and low (yellow squares) FP activity are shown. Analysis of similarity (ANOSIM) demonstrated a significant separation in the composition of fecal microbiotas between high and low FP activity samples using both un-weighted (<i>p</i>=0.001) and weighted (<i>p</i>=0.003) UniFrac distances. The R statistic (where R=1 and R=0 signifies differences and no differences between groups, respectively) is higher in the un-weighted analysis suggesting the separation between microbiotas is a result of both high and low abundances bacterial species.</p
