Bacterial DNA profiles from healthy adult blood samples clustered together and were phylogenetically distinct from the bacterial DNA profiles identified in blood samples from septic ICU patients. A composite unweighted pair group method with arithmetic mean (UPGMA) phylogeny of all the samples was generated with from the jackknife, weighted UniFrac beta-diversity comparison of the DNA profiles from septic ICU patient samples and healthy adult blood samples. The ICU adult blood samples were labeled based on the cluster groups identified in Fig. 1. The taxonomic cluster group’s 1A, 1B, 2AI, 2AII, 2AIV, 3A, and 3B remained intact when clustered with healthy adult blood samples. The DNA profiles from healthy adult blood samples clustered together and were a distinct clade which divided the Group 2AIII cluster. Despite this, the addition of the healthy adult blood samples did not impact the tree structure as the distribution of all three clusters of bacterial DNA profiles from septic ICU patient samples was preserved
