All drugs were tested with the Clinical and Laboratory Standards Institute broth microdilution method at concentrations ranging from 0.015 to 16 μg/ml, except for fluconazole, which ranged in concentration from 0.125 to 128 μg/ml. ANF, anidulafungin; CAS, caspofungin; FLC, fluconazole; MCF, micafungin; VRC, voriconazole.
C. glabrata isolates with known FKS1 or FKS2 mutations or phenotypic or clinical resistance (see the supplemental material).
C. glabrata isolates without known resistance, matched to the resistant isolates by year of recovery.
