Identification of HACEK Clinical Isolates by Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry
Copyright policy )Identification of HACEK Clinical Isolates by Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry
ABSTRACT Matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) mass spectrometry is a rapid and accurate tool for the identification of many microorganisms. We assessed this technology for the identification of 103 Haemophilus parainfluenzae , Aggregatibacter aphrophilus , Aggregatibacter actinomycetemcomitans , Cardiobacterium hominis , Eikenella corrodens , and Kingella kingae (HACEK) clinical isolates and 20 Haemophilus influenzae clinical isolates. Ninety-three percent of HACEK organisms were identified correctly to the genus level using the Bruker database, and 100% were identified to the genus level using a custom database that included clinical isolates.
