Figure 7.
PhyML phylogeny of full-length 16S rRNA gene sequences from type strain isolates in the SILVA ARB database, with the 17 most abundant oligotypes found in this study added by Maximum Parsimony over the 60 bp region. The isolation source for each type strain is color coded at its terminal node. The proportion of MEGABLAST hits that fell into each isolation source category is coded for the 17 oligotype sequences added to the tree, and shown in bar graphs at each oligotype node.
