Abstrakt: Lomentospora prolificansis an opportunistic fungal pathogen with low susceptibility to current antifungal drugs. Here, we tested the in vitrosusceptibility of 8 drugs against 42 clinical L. prolificansisolates. All isolates showed high MICs to voriconazole (MIC90>16 μg/ml), itraconazole (MIC90>16 μg/ml), posaconazole (MIC90>16 μg/ml), isavuconazole (MIC90>16 μg/ml), amphotericin B (MIC90>16 μg/ml), and terbinafine (MIC90>64 μg/ml) and high minimum effective concentrations (MECs) to micafungin (MEC90>8 μg/ml), with the exception of miltefosine showing an MIC90value of 4 μg/ml.
