Performances of the MALDI-TOF Mass Spectrometry system
22 23 Rapid and cost-effective MALDI-TOF MS-based systems will replace conventional 24 phenotypic methods for routine identification of bacteria. We report here the first evaluation 25 of the new MALDI-TOF MS-based VITEK MS system in a large clinical microbiology 26 laboratory. This system used an original spectra classifier algorithm and a specific database 27 designed for the identification o...
متن کاملRapid identification of mycobacteria from positive MGIT broths of primary cultures by MALDI-TOF mass spectrometry
BACKGROUND Rapid identification of mycobacteria is important for timely treatment and the implementation of public health measures. The MGIT system ensures rapid detection of mycobacteria, but identification is usually delayed by days to weeks due to further subculture on solid medium. Matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS) was demonstrated to effective...
متن کاملPerformances and Reliability of Bruker Microflex LT and VITEK MS MALDI-TOF Mass Spectrometry Systems for the Identification of Clinical Microorganisms
In clinical microbiology laboratories, routine microbial identification is mostly performed using culture based methodologies requiring 24 to 72 hours from culturing to identification. Matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) technology has been established as a cost effective, reliable, and faster alternative identification platform. In this s...
متن کاملHead-to-head comparison of Microflex LT and Vitek MS systems for routine identification of microorganisms by MALDI-TOF mass spectrometry in Chile
BACKGROUND Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry (MS) is a new and revolutionary identification method for microorganisms and has recently been introduced into clinical microbiology in many industrialized countries in Europe and North America. OBJECTIVES Our study aimed to compare the performance and practicality of two commercial MALDI-TOF M...
متن کاملRoutine identification of Nocardia species by MALDI-TOF mass spectrometry.
We here show adequate species identification for bacterial isolates of the genus Nocardia spp. through VITEK mass spectrometry. Application of a specific sample preparation method in combination with a robust matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) database leads to 94% accurate identification to the species level on a set of 164 isolates. The...
