In Vitro Antifungal Resistance of Candida auris Isolates from Bloodstream Infections, South Africa.

ABSTRACT: Candida auris is a multidrug-resistant fungal pathogen that is endemic in South African hospitals. We tested bloodstream C. auris isolates that were submitted to a reference laboratory for national laboratory-based surveillance for candidemia in 2016 and 2017. We confirmed the species identification by phenotypic/molecular methods. We tested susceptibility to amphotericin B, anidulafungin, caspofungin, micafungin, itraconazole, posaconazole, voriconazole, fluconazole, and flucytosine using broth microdilution and Etest methods. We interpreted MICs using tentative breakpoints. We sequenced the genomes of a subset of isolates and compared them to the C. auris B8441 reference strain. Of 400 C. auris isolates, 361 (90%) were resistant to at least one antifungal agent, 339 (94%) to fluconazole
