Molecular Identification, Antifungal Susceptibility Testing, and Mechanisms of Azole Resistance in <i>Aspergillus</i> Species Received within a Surveillance Program on Antifungal Resistance in Spain

Abstract

Antifungal resistance is one of the major causes of the increasing mortality rates for fungal infections, especially for those caused by Aspergillus spp. A surveillance program was established in 2014 in the Spanish National Center for Microbiology for tracking resistance in the most prevalent Aspergillus species. A total of 273 samples were included in the study and were initially classified as susceptible or resistant according to EUCAST breakpoints.
