The unit of BP is μg/mL.
Figures in parentheses indicate the number of bacterial strains that were tested for antimicrobial susceptibility.
-: Not under surveillance
As of 2019, no vancomycin-resistant staphylococcus aureus strains had been reported.
* CLSI (2007) (M100-S17) Criteria was applied to determine the BP up to 2013. CLSI (2012) (M100-S22) Criteria was applied to determine BP after 2014.
