Antimicrobial susceptibility testing was performed by the reference broth microdilution method as described in CLSI document M07-A11 [17 ]. The following antimicrobial classes were tested: aminoglycoside, cephalosporin, carbapenem, β-lactamase inhibitor combination, fluoroquinolone, glycylcycline, and polymyxin. Susceptibility rates were calculated using both the 2022 CLSI [5 ] and 2022 US FDA [6 ] breakpoints as well as the recently revised 2023 CLSI breakpoints for aminoglycosides [15 ].
