Evaluation of the Bruker Biotyper and VITEK MS Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry Systems for the Identification of Nonfermenting Gram-Negative Bacilli Isolated From Cystic Fibrosis Patient Cultures

Journal of Clinical Microbiology, 04/13/2012

The agreement of combined species/complex/genus level identification with the reference method was higher for the Bruker Biotyper (97% vs. 89.5%, P=0.004), but required an extraction step more often. Species level agreement with the reference method was similar for both MS systems (72.5% and 80%, P=0.099).
