In vitro activity of nine antifungal agents against clinical isolates of Aspergillus calidoustus.

This study analyzes Aspergillus isolates from the Spanish National Centre for Microbiology collection, which were identified morphologically as members of Aspergillus section Usti. Strains were identified through the analysis of the Internal Transcribed Spacer regions and partial beta tubulin gene sequences. One Aspergillus pseudodeflectus isolate and eight Aspergillus calidoustus isolates were detected in this panel of clinical strains. Terbinafine and the echinocandins micafungin and anidulafungin, were the drugs most active against these species.
