Monitoring Antifungal Resistance in a Global Collection of Invasive Yeasts and Molds: Application of CLSI Epidemiological Cutoff Values and Whole-Genome Sequencing Analysis for Detection of Azole Resistance in Candida albicans.

ABSTRACT: The activity of 7 antifungal agents against 3,557 invasive yeasts and molds collected in 29 countries worldwide in 2014 and 2015 was evaluated. Epidemiological cutoff values (ECVs) published in the Clinical and Laboratory Standards Institute (CLSI) M59 document were applied for species with no clinical breakpoints. Echinocandin susceptibility rates were 95.9% to 100.0% for the 5 most common Candida species, except for the rates for Candida parapsilosis to anidulafungin (88.7% susceptible, 100.0% wild type). Rates of fluconazole resistance ranged from 8.0% for Candida glabrata to 0.4% for Candida albicans Seven Candida species displayed 100.0% wild-type amphotericin B MIC results, and Candida dubliniensis and Candida lusitaniae exhibited wild-type echinocandin MIC results. The highest fluco
