Environmental surveillance reveals uneven distribution of Aspergillus terreus in Tyrolean soils, highlighting widespread azole resistance.

Key Points

To identify environmental factors influencing the uneven geographical prevalence of Aspergillus terreus in Austrian soils and assess their antifungal susceptibility profiles.
Collected and analyzed soil samples from eastern and western Tyrol alongside nationwide Austrian samples using soil extraction plating, soil immersion tubes, and species-specific qPCR.
Evaluated soil chemical and physical characteristics (pH, moisture, organic matter, total carbon, nitrogen, density) and determined antifungal susceptibility for amphotericin B, posaconazole, isavuconazole, and voriconazole via EUCAST guidelines.
Aspergillus terreus prevalence was significantly higher in eastern Tyrol compared to western Tyrol and other Austrian regions, correlating significantly with lower soil pH, decreased total carbon and nitrogen, and lower soil density.
Antifungal profiling demonstrated 100% resistance to posaconazole and 87.2% resistance to isavuconazole, whereas 98.3% of isolates exhibited wild-type susceptibility to amphotericin B and 100% were wild type for voriconazole.
