a Type of population studied: Hospital (H)/Community (C). b Percentage positivity for AmpC among all isolates evaluated in the study. c Percentage global positivity that includes species other than E. coli and K. pneumoniae and/or does not differentiate between cAmpC-BL and pAmpC-BL. PCR: polymerase chain reaction; WGS: whole genome sequencing; ECI: E. coli isolates; 3GCR: third-generation cephalosporin-resistant; EI: Enterobacteriaceae isolates; KPI: K. pneumoniae isolates; ESBL: extended spectrum beta-lactamase.
