aN/A, not applicable; GM, geometric mean; CBP, clinical breakpoint; ECV, epidemiology cut-off value; S, susceptible; SDD, susceptible dose dependent; I, intermediate; R, resistant; WT, wild-type strain; AFG, anidulafungin; MFG, micafungin; CFG, caspofungin; AmB, amphotericin B; 5-FC, 5-flucytosine; PSO, posaconazole; VRC, voriconazole; ITC, itraconazole; FLU, fluconazolea. bInterpretation (CBP and ECV: ug/ml) of susceptibility testing were in accordance with the recommendation of the CLSI for C. albicans; CBPs: Anidulafungin, Micafungin and Caspofungin: S < 25, 1 = 0.5, R > 1; Voriconazole: S < 0.12, SDD = 0.25-0.5, R > 1; Fluconazole: S < 2, SDD = 4, R > 8; ECVs, Anidulafungin = 0.12; Micafungin = 0.03; Amphotericin B = 2.
