Multicenter validation of the VITEK MS v2.0 MALDI-TOF mass spectrometry system for the identification of fastidious gram-negative bacteria

John A Branda et al. Diagn Microbiol Infect Dis. 2014 Feb.

Abstract

The VITEK MS v2.0 MALDI-TOF mass spectrometry system's performance in identifying fastidious gram-negative bacteria was evaluated in a multicenter study. Compared with the reference method (DNA sequencing), the VITEK MS system provided an accurate, species-level identification for 96% of 226 isolates; an additional 1% were accurately identified to the genus level.

Keywords: Fastidious; Gram-negative bacilli; Identification; MALDI-TOF MS; VITEK.
