Inference of the staphylococcal phylogeny using Bayesian estimation of species trees (BEST) methodology on 16S rRNA and dnaJ gene fragments. Shown is a consensus phylogram of the staphylococcal species tree generated under the BEST methodology incorporating only 16S rRNA and dnaJ gene fragments. Each of the two gene fragments were treated as an individual locus for which individual gene trees were estimated. Numbers represent posterior probabilities with grey-filled circles representing a posterior probability of 1.00. Refer to Additional file 7: Figure S5 for the BEST analysis incorporating all four gene fragments.
