FIG 2.

Minimum-spanning tree of 139 M. abscessus complex isolates based on the three-gene and thirteen-gene MLST schemes. Strains clustered together by the three-gene scheme was depicted as circles, segments within the circles depict more than one isolate clustered together by the thirteen-gene schemes. Different colors within one circle represent different sequence types determined by the thirteen-gene MLST that were indistinguishable by the three-gene MLST.
