a
M. marinum/M. ulcerans and M. szulgai/M. malmoense cannot be identified to the species level by the CapitalBio Mycobacterium identification array. The 16S rRNA sequencing showed that 4 strains identified as M. marinum/M. ulcerans were 3 strains of M. marinum and 1 strain of M. ulcerans and that 3 strains identified as M. szulgai/M. malmoense were 2 strains of M. szulgai and 1 strain of M. malmoense.
