Principle coordinate analysis (PCoA) of (A) Unweighted (<i>P = 0</i>.<i>0003</i>) and (B) Weighted (<i>P</i> = 0.06) UniFrac distances, an OTU based unsupervised measure of beta-diversity in fecal samples collected before induction of colitis.

<p>Fecal samples clustered according to the treatment. The clustering was further influenced by the mother especially in the unweighted analysis (<i>P</i> = 0.001). The <i>P</i> values were determined using PERMANOVA. 10 mice per group. ControlM1 and ControlM2 shows mice in the control group but from two different mothers; ATBm1 and ATBm2 shows mice in the ATB (antibiotic) group but from two different mothers.
