From: High genetic heterogeneity of Mycobacterium intracellulare isolated from respiratory specimens
Minimum spanning tree of the 39 M. intracellulare strains. Each circle represents a VNTR profile; the number inside the circle identify the strain corresponding to the VNTR profile. Size of circles is proportional to the number of isolates sharing the VNTR profile. Numbers next to the branches indicate the level of changes induced by loss or gain of VNTR copies at a given locus, yielding a change from one allele to another. Surrounding grey indicates the clonal complexes
