Overview

Randomized trial evaluates MALDI-TOF-MS for identifying viridans streptococci, suggesting a reliable diagnostic method.

Key Points

  • This study aims to assess the effectiveness of MALDI-TOF-MS for rapid identification of viridans streptococci species from clinical samples.
  • Analyzed 99 clinical isolates, 10 reference strains, and 20 in-house strains using MALDI-TOF-MS.
  • Identified strains in parallel with phenotypic and genotypic methods for accuracy comparison.
  • Focused on ten different species of viridans streptococci.
  • MALDI-TOF-MS identified 71 isolates as the mitis group, 23 as the anginosus group, and 5 as Streptococcus salivarius.
  • Achieved 100% consistency in species identification compared to phenotypic and genotypic methods.
