Genetic distances between MLST DNA sequences within AT-groups. The genetic distance between MLST DNA sequences is shown for AT-groups F469, 4B9A and EC2A. Each graph represents on the horizontal axis the genetic distance to the dominant MLST-ST within the AT-group and, on the vertical axis, the absolute frequency of each ST.
