MALDI-TOF mass spectrometry

Accelerated Techniques of Pathogen Identification from Positive Blood Cultures by MALDI-TOF Mass Spectrometry

Objective. To assess pathogen identification from positive blood cultures by MALDI-TOF mass spectrometry. Materials and Methods. At the first stage, an in vitro study using MALDI-TOF MS and including 11 pathogen species (K. pneumoniae, E. coli, P. aeruginosa, A. baumannii, S. aureus, S. epidermidis, S. haemolyticus, E. faecalis, E. faecium, C. albicans, C. parapsilosis) was performed. This study involved hourly attempts to identify the above listed pathogens by MALDI-TOF MS (Vitek MS, bioMerieux) during incubation until their correct identification.
