Susceptibility testing of anidulafungin and voriconazole alone and in combination against conidia and hyphae of Aspergillus spp. under hypoxic conditions

Abstract

MICs and fractional inhibitory concentrations were evaluated for anidulafungin and voriconazole alone and in combination against conidia and hyphae under hypoxic (1% oxygen-5% CO2-94% nitrogen) conditions against 31 Aspergillus isolates. Anidulafungin exhibited excellent activity against conidia and hyphae of Aspergillus spp. The visual reading of the MIC for anidulafungin was optimal under hypoxic conditions.
