Fig. 2

Minimum spanning tree of all 28 isolates based on the allelic profiles of the stable Bcg cgMLST scheme. Each circle represents the genotype based on a unique allelic profile of up to 1568 cgMLST genes, and the number on connecting lines displays the number of differing alleles in the pairwise comparison. The circles are named with the isolate labels and colored according to their origin (white = Patients, gray = Environment)
