Densitree of 130 STs belonging to the MAB. The phylogenetic reconstruction is based on the concatenated housekeeping genes (3576 bp) and the GTR + I + G evolutionary model was implemented in BEAST 1.7.5. The best 8000 trees generated during the Markov chain are drawn transparently (in green). As a result, areas where the vast majority of the trees agree in topology and branch lengths show up as deep green, while areas with little agreement show up as webs. The root canal tree (blue lines) has a topology that is selected from the set of trees and has the highest probability of clades in the set. The scale corresponds to the genetic distance
