C. famata (3, 27)
    MicroScan (Beckman Coulter)C. famata, C. lusitaniae, C. guilliermondii, C. parapsilosis, C. albicans, C. tropicalis (12, 31)
MALDI-TOF MS
    Vitek MS (bioMérieux)C. albicans, C. haemulonii (29)
Not identified (28, 36)
    MALDI Biotyper (Bruker Daltonics)Neisseria meningitides serogroup A, Pseudomonas rhizosphaerae (29)a
  • a Subsequently, samples were identified as containing C. auris by ITS sequencing of ear swab samples; the bacteria isolated by MALDI-TOF MS likely represent colonizing bacteria.
