This is a panel of Staphylococcus aureus isolates with variable susceptibility to oxacillin. Isolates with mecA-mediated oxacillin resistance are ones for which the MIC is close to the resistant breakpoint. This panel can be used as a rigorous challenge of diagnostic tests that measure oxacillin susceptibility or mecA-mediated resistance.
Panel ID: BORSA
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: 2841-2844).
