Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass
spectrometry has emerged as a reliable technique to identify molds involved in
human diseases, including dermatophytes, provided that exhaustive reference
databases are available. This study assessed an online identification application
based on original algorithms and an extensive in-house reference database
comprising 11,851 spectra (938 fungal species and 246 fungal genera). Validation
criteria were established using an initial panel of 422 molds, including
dermatophytes, previously identified via DNA sequencing (126 species). The
application was further assessed using a separate panel of 501 cultured clinical
isolates (88 mold taxa including dermatophytes) derived from five hospital
laboratories. A total of 438 (87.35%) isolates were correctly identified at the
species level, while 26 (5.22%) were assigned to the correct genus but the wrong
species and 37 (7.43%) were not identified, since the defined threshold of 20 was
not reached. The use of the Bruker Daltonics database included in the MALDI
Biotyper software resulted in a much higher rate of unidentified isolates (39.76
and 74.30% using the score thresholds 1.7 and 2.0, respectively). Moreover, the
identification delay of the online application remained compatible with real-time
online queries (0.15 s per spectrum), and the application was faster than
identifications using the MALDI Biotyper software. This is the first study to
assess an online identification system based on MALDI-TOF spectrum analysis. We
have successfully applied this approach to identify molds, including
dermatophytes, for which diversity is insufficiently represented in commercial
databases. This free-access application is available to medical mycologists to
improve fungal identification.
