The in vitro activity of AMPH-B, 5-FC, FLCZ, MCZ, ITCZ, and VRCZ against 50 isolates of T. asahii was determined using CLSI M27-A2 microdilution and ASTY colorimetric methods. Observed agreement ranged from 96 to 100% according to the drug. Overall, the agreement between two methods was 97.7%. The ASTY colorimetric method was thus determined to be comparable to the CLSI reference method when testing the susceptibility of T. asahii to a variety of antifungal agents.
