FIG. 4.

Rep-PCR-based dendrogram and virtual gel image fingerprints obtained from 42 CIs of M. abscessus, M. massiliense, and M. bolletii and the corresponding type strains (ATCC 19977, CIP 108297, and CIP 108541, respectively). The DiversiLab system with the Mycobacterium sp. fingerprinting kit was used. Pearson's correlation coefficient was used to create a pairwise percent similarity matrix, and the tree was generated by the unweighted pair group method with arithmetic means (UPGMA). Bar, percent similarity among strains.
