We compared EUCAST and CLSI methods versus Etest for antifungal susceptibility testing of 20 clinically relevant Fusarium species against amphotericin B, posaconazole, and voriconazole. The median Etest amphotericin B and posaconazole MICs were 1 dilution higher than the median EUCAST and the CLSI MICs. The essential agreement (within +/-1/+/-2 dilutions) was 60/90%, 80/95%, and 70/85% between the Etest and EUCAST methods and 80/95%, 75/95%, and 45/100% between the Etest and CLSI methods for amphotericin B, voriconazole, and posaconazole, respectively. The categorical agreement was >85%. Etest can be used for antifungal susceptibility testing of Fusarium species.
