Fig. 1: Population structure of MRSA in the Netherlands.

The minimum spanning tree is based on categorical clustering of wgMLST data of 4798 MRSA isolates (first isolate per person). Each circle represents one or more MRSA isolates with the same wgMLST profile. Genogroups are indicated by colors and text. The distances between the genogroups, represented by the connecting lines, are at least 1000 wgMLST loci.
