Identification of mycobacteria by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry.

Classical methods for identification of Mycobacterium species rely on morphology and biochemical profiles. Speciation of a Mycobacterium isolate using these standard methods is a lengthy process based on subjective data interpretation. In this study, Mycobacterium species were characterized by utilizing matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS).
