<i>In Vitro</i> Antifungal Susceptibility of Clinically Relevant Species Belonging to Aspergillus Section <i>Flavi</i>

Abstract

The in vitro antifungal susceptibility of 77 isolates belonging to different clinically relevant species of Aspergillus section Flavi, including those of different phylogenetic clades of A. flavus, was tested for nine antifungal agents using a microdilution reference method (CLSI, M38-A2). Terbinafine and the echinocandins demonstrated lower MICs/MECs for all species evaluated, followed by posaconazole. Amphotericin B showed MICs ≥ 2 μg/ml for 38 (49.4%) of the 77 isolates tested.
