Figure 1

Minimum spanning tree of 116 Escherichia coli isolates, using core-genome multilocus sequence typing (MLST) analysis comprising 2513 genes (BioNumerics E. coli/Shigella EnteroBase scheme). A tree with the highest resampling support is shown, using 1000-resampling bootstrapping. (A) Isolates carrying the pco gene cluster are highlighted in orange; (B) isolates carrying the resistance genes blaCTX-M, blaCMY, tet(A), and tet(B) are indicated. Letters in 1A indicated single-nucleotide polymorphism (SNP) types found in Figure 2. Circles containing multiple sections indicate multiple isolates within a core-genome sequence type. Isolates used for minimum inhibitory concentration (MIC) testing are also highlighted and labeled in 1A.
