A nationwide passive surveillance on fungal infections shows a low burden of azole resistance in molds and yeasts in Tyrol, Austria

Abstract

Purpose: To determine the burden of antifungal resistance in fungi over the last 10 years. Methods: Performance of a semi-nationwide surveillance on antifungal resistance. Results: We observed a low frequency of azole resistance in Aspergillus fumigatus, a moderate increase of echinocandin resistance in yeasts, and a stable amphotericin B activity in yeasts and molds. Posaconazole resistance in Aspergillus terreus occurred in a few isolates. Conclusion: The burden of resistance in fungi seems to be low in Tyrol, Austria.
