The antifungal susceptibilities of 79 oral Candida glabrata isolates to fluconazole and voriconazole were compared. The MICs at which 90% of the isolates tested were inhibited were 1 microg of voriconazole/ml and 32 microg of fluconazole/ml. Oral C. glabrata isolates for which the fluconazole MICs are elevated are commonly those for which the voriconazole MICs are elevated, but these increases may be transient for voriconazole, as they are for fluconazole.
