Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry Is a Sensitive and Specific Method for Identification of Aerococci

Conventional methods for the identification of human-pathogenic aerococci to the species level are not reliable. We show that matrix-assisted laser desorption ionization-time of flight mass spectrometry correctly identifies aerococci to the species level and that it can be used to identify aerococci with high specificity in the diagnostic clinical microbiology laboratory.
