Three clustered cases of candidemia caused by Candida quercitrusa and mycological characteristics of this novel species

Abstract

We investigated three nosocomial Candida quercitrusa candidemia cases occurring within 2 months in a Chinese hospital. Isolates were identifiable only by DNA sequencing of the rRNA genes. Genetic (via random amplified polymorphic DNA [RAPD]) and protein mass spectral (via matrix-assisted laser desorption ionization-time of flight mass spectrometry [MALDI-TOF MS]) analyses yielded identical profiles suggesting an outbreak. The fluconazole MICs of all the strains were 16 to 32 μg/ml. Copyright © 2014, American Society for Microbiology. All Rights Reserved.
