^aPBP3-mediated resistance (see Table 1).

^bBeta-lactamase positive (all TEM-1).

^cProportions for each ST were compared with the proportions for other STs (e.g. ST396 versus non-ST396) using Fisher’s exact test. Characteristics significantly more prevalent in particular STs are indicated (bold).

^dProportions of patients hospitalized at the time of sampling.

^ep < 0.05.

^fp = 0.004.
