Distribution of dBLIM inhibition zone diameters among blood cultures spiked with ESBL-producing Enterobacterales, AmpC-type-β-lactamase-producing Enterobacterales, and extended-spectrum-β-lactamase/AmpC-type-β-lactamase/carbapenemase-nonproducing Enterobacterales. Breakpoints and interpretation criteria were as follows: for ES/ACBL/CARB-nonproducing EB, the MEM diameter was >15 mm and the CTX diameter was >14 mm; for ESBL/ACBL-producing EB, the MEM diameter was >15 mm and the CTX diameter was ≤12 mm; for carbapenemase-producing EB, the MEM diameter was ≤12 mm; and for disks with ATUs, the MEM diameter was 13 to 14 mm and the CTX diameter was 13 mm. Abbreviations: BC, blood culture; ESBL, extended-spectrum-β-lactamase; ACBL, AmpC-type β-lactamase; np-ESBL/ACBL/CARB, extended-spectrum-β-lactamase/AmpC-type-β-lactamase/carbapenemase-nonproducing; EB, Enterobacterales; ATU, area of technical uncertainty.
