Figure 1.
Minimum spanning tree of Yersinia cgMLST profiles: Branch lengths are drawn in log scale. For each node, MLST sequence type number is indicated. Coloured nodes represent virulent or non-virulent Y. enterocolitica biotypes that were determined based on presence of ail, inv, ystA and ystB genes. Uncoloured nodes represent non-enterocolitica species for which this biotype determination was not applicable.
