Fig. 7

Proportion of Salmonella genomes containing QRDR mutations (black) among all genomes in the 25 most frequent HC900 clusters (colored) in EnteroBase [3]. HC900 clusters consist of hierarchical single-linkage clusters with maximal internal cgMLST distances of 900 alleles, which correlate well with Salmonella serovars. Nodes in the figure are colored and labeled by their majority serovar https:// enterobase.readthedocs.io/en/latest/HierCC_lookup.html). The neighbor-joining tree of all genomes in these clusters is based on 7-gene MLST distances and was visualized in GrapeTree [5]. For each cluster, the figure legend indicates the number of genomes with and without the QRDR mutation, and its percentage
