FIG. 1 Distribution of isolates according to minimal inhibitory concentrations (MIC) of cefotaxime, ceftazidime, cefepime, piperacillin/tazobactam, amoxicillin/clavulanic acid and ertapenem, and by extended-spectrum β-lactamase (ESBL) group produced. Black bars, CTX-M-9 group; grey bars, CTX-M-1 group; white bars, SHV group, only isolates producing one ESBL are included. The most frequent ESBL per group was: CTX-M-14 in the CTX-M-9 group; CTX-M-15 in the CTX-M-I group; SHV-12 in the SHV group. It should be noticed that the MIC scale differs for ertapenem.
