MIC–zone diameter (ZD) correlations for cefiderocol for Enterobacterales (a), E. coli (b), K. pneumoniae (c), P. aeruginosa (d), A. baumannii (e), S. maltophilia (f). Each isolate was tested with cefiderocol discs from two manufacturers and on Mueller–Hinton media from two manufacturers, resulting in four correlates per isolate. Green = susceptible/below PK/PD MIC BP; orange/red = resistant/above PK/PD MIC BP; Red dotted line = ZD BP (Enterobacterales and P. aeruginosa) or ZD cut-off (A. baumannii and S. maltophilia).
