FIG 1.

Maximum likelihood tree of Mycobacterium abscessus complex. A maximum likelihood tree was built from 222,210 core SNP sites of 70 M. abscessus complex (MABC) isolates from 37 patients and 11 published strains (see Tables S1 and S2 in the supplemental material). All sequenced genomes were mapped to the M. abscessus ATCC 19977 genome as a reference genome, and the mean coverage was 82×. MABC isolates classified as M. abscessus subsp. abscessus are represented in green. Likewise, M. abscessus subsp. massiliense isolates are represented in blue and M. abscessus subsp. bolletii isolates are represented in red on the tree. The first and last isolate from each patient is indicated by a and b, respectively. Single isolates were available only from patients 25, 26, 35, and 37. *, isolates recovered from non-CF patients in this study. Published MABC strains are highlighted in bold.
