VNTR genotypes of <i>M. ulcerans</i>, mycolactone producing <i>M. marinum and M. pseudoshottsii</i> (MPM), and <i>M. liflandii</i> (MPML).

VNTR typing was based upon numbers of repeats found at different loci MIRU1, Locus 6, ST1, and Locus 19.可变数目串联重复序列（Variable Number Tandem Repeats，VNTR）分型基于不同位点MIRU1、位点6、ST1及位点19处的重复序列拷贝数。
