Neighbor-joining tree of a 1,341-bp region of unique 16S rRNA gene sequences of 138 clinical isolates and reference strains of the Mycobacterium chelonae-abscessus complex. Branch support is recorded at nodes as a percentage of 1,000 bootstrap iterations. Clinical isolates are labeled by the identification, followed by the sequevar group and the number of isolates. Scale bar indicates nucleotide substitutions per site.
