This study presents the antifungal susceptibility patterns of members affiliated with both entities. Clinical and environmental isolates (n = 332) from a wide range of sources and origins were identified down to species level and tested according to CLSI M38-A2 against eight antifungal compounds. Whereas P. apiosperma (geometric mean MIC/minimal effective concentration MEC values of 0.9, 2.4, 7.4, 16.2, 0.2, 0.8, 1.5, and 6.8 μg/ml for voriconazole, posaconazole, isavuconazole, itraconazole, micafungin, anidulafungin, caspofungin, and amphotericin B, respectively) and P. boydii (geometric mean MIC/MEC values of 0.7, 1.3, 5.7, 13.8, 0.5, 1.4, 2.3, and 11.8 μg/ml for voriconazole, posaconazole, isavuconazole, itraconazole, micafungin, anidulafungin, caspofungin, and amphotericin B, respectively) had similar susceptibility patterns, those for S. aurantiacum, S. prolificans, and S. dehoogii were different from each other. Voriconazole was the only drug with significant activity against S. aurantiacum isolates. The MIC distributions of all drugs except voriconazole did not show a normal distribution and often showed two subpopulations, making a species-based prediction of antifungal susceptibility difficult. Therefore, antifungal susceptibility testing of all clinical isolates remains essential for targeted antifungal therapy. Voriconazole was the only compound with low MIC values (MIC(90) of ≤ 2 μg/ml) for P. apiosperma and P. boydii. Micafungin and posaconazole showed moderate activity against the majority of Scedosporium strains.
