C. auris-specific antifungal susceptibility interpretation according to CDC [21].

Antifungal	MIC	Interpretation
Fluconazole	≥32	Isolates with MIC ≥ 32 were shown to have a mutation of the Erg11 gene
Voriconazole	NA	Consider using fluconazole susceptibility as a surrogate for other azoles. Occasionally, isolates that are resistant to fluconazole may respond to voriconazole
Amphotericin B	≥2	Isolates with a MIC of ≥2 should be considered to be resistant
Anidulafungin	≥4	Breakpoints are based on the distribution of echinocandin MICs of approximately 100 isolates from diverse geographic locations
Caspofungin	≥2
Voriconazole	≥4

MIC: minimum inhibitory concentration.
