Abstract

The antifungal susceptibility of Aspergillus cryptic species is poorly known. We assessed 51 isolates, belonging to seven Fumigati cryptic species, by the EUCAST reference method and the concentration gradient strip (CGS) method. Species-specific patterns were observed, with high MICs for azole drugs, except for Aspergillus hiratsukae and Aspergillus tsurutae, and high MICs for amphotericin B for Aspergillus lentulus and Aspergillus udagawae Essential and categorical agreements between EUCAST and CGS results were between 53.3 and 93.3%.

Keywords: Aspergillus lentulus; Aspergillus section Fumigati; Aspergillus thermomutatus; MALDI-TOF mass spectrometry; antifungal susceptibility testing; azole resistance; cryptic species.
