Fig. 2. Antimicrobial susceptibility and frequency of MDR phenotype. Antimicrobial susceptibility of (A) CC398 and (B) non-CC398 MRSA isolates and frequency of a MDR phenotype among (C) CC398 and (D) non-CC398 MRSA isolates. Susceptibility assays were performed using the disc diffusion methods according to the 2017 Clinical and Laboratory Standards Institute guidelines [17].
