Identification of non-tuberculous mycobacteria using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry

Matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS) is a new tool for species identification of non-tuberculous mycobacteria. We evaluated this method on 15 NTM clinical isolates. MALDI-TOF MS is a promising new tool for fast and reliable identification of NTM species. In some cases NTM species identification is correct despite score values indicating only probable genus identification. With improvement of extraction protocol higher score values could be regularly achieved making this method one of the first choices for the identification of NTM species.
