Fig. 3From: Automated image analysis for quantification of filamentous bacteriaEarly detection of antibiotic-induced filamentation of ESBL-producing E. coli by β-lactam–β-lactamase inhibitor combinations. Growth kinetics and mean bacterial length of E. coli treated with piperacillin/tazobactam (32/4 mg/L) (a–b) or ticarcillin/clavulanic acid (32/2 mg/L) (c–d). The piperacillin/tazobactam-induced filamentation (increased length >5 μm) can be determined within 30 min, while the absence of ticarcillin/clavulanic acid-induced filamentation can be determined within 40 minBack to article page
