We determined the in vitro activities of anidulafungin, caspofungin, and micafungin against 526 isolates of Aspergillus spp. (64 A. flavus, 391 A. fumigatus, 46 A. niger, and 25 A. terreus isolates) collected from over 60 centers worldwide from 2001 through 2007. Susceptibility testing was performed according to the CLSI M38-A2 method. All three echinocandins--anidulafungin (50% minimum effective concentration MEC₅₀, 0.007 μg/ml; MEC₉₀, 0.015 μg/ml), caspofungin (MEC₅₀, 0.015 μg/ml; MEC₉₀, 0.03 μg/ml), and micafungin (MEC₅₀, 0.007 μg/ml; MEC₉₀, 0.015 μg/ml)--were very active against Aspergillus spp. More than 99% of all isolates were inhibited by less-than or equal to0.06 μg/ml of all three agents.
