^*Data are numbers (percentages). Numbers are based on records with any minimum inhibitory concentrations (MICs). About 1% of all records for all times were missing MICs for 1 or 2 drug classes.

^†The tentative MIC breakpoint for fluconazole was ≥32 mcg/mL.

^‡The tentative MIC breakpoint for amphotericin B was ≥2 mcg/mL.

^§The tentative MIC breakpoint for echinocandins was ≥4 mcg/mL (anidulafungin or micafungin).

^∥The Central region is excluded because of the small number of isolates.
