2.2 Antimicrobial susceptibility test
The antimicrobial susceptibility testing was performed using the agar dilution method to determine the minimum inhibitory concentrations (MICs) of the isolates. Antibiotics used in the study were listed in Table 1. The results of antimicrobial resistance were interpreted according to the clinical and laboratory standard institute (CLSI) 2018 guidelines (CLSI, 2018).
