Differentiation in bacterial communities from all participants (interpersonal variations). Community differentiation was measured by using the unweighted UniFrac algorithm; the scale bar indicated the distance between clusters in UniFrac units. All of the branch nodes shown here were found to be significant, indicating that bacterial community from each habitat was divided into a distinctive cluster.
