New VITEK® MS Update Enables ID of Mycobacteria, Nocardia & Moulds
VITEK® MS is the first MALDI-TOF MS (Matrix Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry) system to have an IVD-CE marked database for the identification of mycobacteria, Nocardia and moulds*. Along with the database expansion, bioMérieux offers inactivation and extraction reagent kits to make rapid testing for these clinically important species safe and easy.
MALDI-TOF MS technology provides clear and accurate identification at the species, group, or genus level in minutes. While the VITEK® MS system has for years been able to reliably identify numerous bacteria and yeasts for clinical diagnosis, it now brings an important addition with high-performance rapid identification of mycobacteria, Nocardia and moulds1. Timely identification of these organisms helps in the management of diseases such as tuberculosis, serious fungal infections and osteomyelitis caused by non-tuberculosis mycobacteria (NTM).
These species come as part of a database update that makes VITEK® MS particularly comprehensive with 1,046 species and 15,172 distinct strains of bacteria, yeasts and moulds. New in the database are:
- 49 mycobacteria taxa comprised of 48 species
- 14 Nocardia species
- 48 mould taxa comprised of 47 species
- 197 other new bacteria and yeasts
VITEK® MS is a market-leading MALDI-TOF MS system with a unique algorithm (Advanced Spectra Classifier) that provides excellent discrimination between species. The database also accounts for diversity within a species for greater accuracy without the need to manipulate result scores to obtain species identification2.
The system is part of bioMérieux’s comprehensive and complementary range of ID/AST solutions for infectious disease diagnostics. VITEK® MS and VITEK® 2 together provide flexibility aimed at optimizing laboratory workflow to allow rapid results that support the selection of appropriate antimicrobial treatment. VITEK® solutions offer rapid, accurate results, whether for routine diagnoses, unusual or resistant organisms, or critical clinical situations.
