In-vitro activity of voriconazole (UK-109,496), LY303366 and other antifungal agents against oral Candida spp. isolates from HIV-infected patients

Abstract

In this report we compare the activity of two new antifungal agents, voriconazole (UK-109,496) and LY303366 with the activities of other antifungals including fluconazole, itraconazole, 5-fluorocytosine (5FC) and amphotericin B against 219 oral Candida spp. isolates from HIV-infected patients. We used the broth microdilution method following the guidelines of the NCCLS. The in-vitro activity of voriconazole (UK-109,496) (MIC₉₀ 0.12 mg/L) and LY303366 (CMI₉₀ 0.25 mg/L) against clinical isolates of Candida spp. was excellent and comparable with that of amphotericin B (MIC₉₀ 0.5 mg/L), and better than those of fluconazole (MIC₉₀ ≥ 64 mg/L), itraconazole (MIC₉₀ 4 mg/L) and 5FC (MIC₉₀ 1 mg/L).
