Fig. 3From: Nontuberculous mycobacteria isolated from specimens of pulmonary tuberculosis suspects, Northern Tunisia: 2002–2016Phylogenetic tree based on rpoB gene using NJ method with Kimura 2-parameter distance correction model. The significance of branches (when > 50) is indicated by bootstrap values calculated on 1000 replicates. Bar, 1 substitution per 100 amino acid residues. PNTMs that could not be identified to the species level are highlighted in redBack to article page
