CGH patterns for four putative deletions that were selected as candidates to distinguish M. massiliense from M. abscessus. The normalized log₂ signal ratios for individual probes in selected genomic regions are shown for M. abscessus and M. massiliense strains. Consistent log ratios (y axis) near 0 indicate that genomic DNA is present throughout these regions in M. abscessus clinical isolate CI79 and in the reference genome (M. abscessus type strain ATCC 19977). In contrast, the M. massiliense type strain CCUG 48898 and M. massiliense clinical isolates CI11, CI154, and CI76 show regions with negative ratios, suggesting the absence of genomic DNA at those locations.
