In vitro susceptibilities of 11 clinical isolates of Exophiala species to six antifungal drugs.

The antifungal activities of miconazole, terbinafine, itraconazole, UR 9825, voriconazole and amphotericin B against 11 clinical isolates of Exophiala spp. were tested by the broth microdilution method. All drugs were very active against Exophiala spp.. The 90% minimal inhibitory concentration (MIC90) ranged from 0.125 to 1 microgram ml-1. Terbinafine was the most active drug against Exophiala spinifera, Exophiala dermatitidis and Exophiala castellanii and seems to be a promising agent in the treatment of infections caused by these fungi.
