Abstract
We aim in this study to provide levels of susceptibility of 162 bloodstream isolates of non-Candida albicans and non-C. tropicalis species from a sentinel program conducted in 11 hospitals in Brazil. Additionally, we compared the broth microdilution (BMD) method of the European Committee of Susceptibility Testing (EUCAST) with Clinical Laboratory Standards Institute (CLSI) BMD method for fluconazole, itraconazole, voriconazole, and amphotericin B. The study included 103 C. parapsilosis, 38 C. glabrata, 8 C. orthopsilosis, and 7 C. krusei isolates, and single isolates of Pichia anomala, C. famata, C. lusitaniae, C. kefyr, C. guilliermondii, and C. metapsilosis. Of note, we observed cross-resistance between fluconazole and voriconazole for two isolates being one C. parapsilosis and one C. glabrata. Good essential agreement (EA) was observed between the EUCAST and the CLSI results for C. parapsilosis and for fluconazole, itraconazole, voriconazole, and amphotericin B, respectively: 98%, 99%, 98%, and 97%. Otherwise, for C. glabrata, the EA for fluconazole was 84.2% and for voriconazole 89.4%. Because data from Brazil are scarce, our results contribute to the consolidation of the database of candidemia agents and monitoring of trends in the profile of drug resistance.
