Species identification of clinical Prevotella isolates by matrix-assisted laser desorption ionization-time of flight mass spectrometry

Ingrid Wybo et al. J Clin Microbiol. 2012 Apr.

Abstract

The performance of matrix-assisted laser desorption-ionization time of flight mass spectrometry (MALDI-TOF MS) for species identification of Prevotella was evaluated and compared with 16S rRNA gene sequencing. Using a Bruker database, 62.7% of the 102 clinical isolates were identified to the species level and 73.5% to the genus level. Extension of the commercial database improved these figures to, respectively, 83.3% and 89.2%. MALDI-TOF MS identification of Prevotella is reliable but needs a more extensive database.
