RESUMO
Since the early 1980s, mass spectrometry has emerged as a particularly powerful tool for analysis and characterization of proteins in research. Recently, bacteriologists have focused their attention on the use of mass spectrometry (MS) for bacterial identification, especially Matrix Assisted Laser Desorption Ionization Time-Of-Flight (MALDI-TOF). Moreover, recent publications have evaluated MALDI-TOF in microbiology laboratory for routine use. MALDI-TOF-MS is a rapid, precise, and cost-effective method for identification of intact bacteria, compared to conventional phenotypic techniques or molecular biology. Furthermore, it allows identification of bacteria directly from clinical samples (blood cultures for example). The goal of this review was to update recent data concerning routine identification of microorganisms by MALDI-TOF in the clinical microbiology laboratory.
