Phylogenetic tree based on concatenated rpoB, 16S rRNA, hsp65 and sodA gene sequences using NJ method with Kimura 2-parameter distance model. The significance of branches (when > 50) is indicated by bootstrap values calculated on 1000 replicates. Bar, 5 substitutions per 100 amino acid residues. PNTMs that could not be identified to the species level are highlighted in red
