Among 400 Aspergillus species from respiratory samples in Switzerland, Aspergillus fumigatus was the most frequent species. Non-fumigatus Aspergillus spp were more prevalent among solid organ transplant recipients and after azole exposure. Azole resistance was detected in 4 A fumigatus isolates, 3 of them with the "environmental" mutation TR34/L98H in the cyp51A gene.
Keywords: Aspergillus fumigatus; TR34/L98H mutation; azole resistance; cyp51A gene; non-fumigatus Aspergillus spp.
