A panel of Escherichia coli, Klebsiella pneumoniae and Klebsiella oxytoca isolates with resistance to at least one extended-spectrum cephalosporin (ceftazidime, cefotaxime, or ceftriaxone) and non-resistant (i.e., susceptible or intermediate) to carbapenems. Some isolates harbor extended- spectrum beta-lactamases (ESBLs) and were collected in 2017, through the Multi-site Gram-negative Surveillance Initiative (MuGSI), part of the CDC’s Emerging Infections Program (EIP) Healthcare-Associated Infections Community Interface (HAIC) activity.
Panel ID: ESBL
MICs obtained by broth microdilution. Modal MIC is reported.
MIC results for each antimicrobial agent for an isolate may commonly be ± 1 log2 (doubling dilution) different than what is posted on the FDA & CDC AR Bank website because this is the normal technical variability of antimicrobial susceptibility testing (see J. H. Jorgensen. 1993. J Clin Microbiol. Vol 31[11]: 2841-2844).
