摘要：

Matrix-assisted laser desorption ionization-time of flight mass spectrometry for identification of Nocardia species remains challenging. By identifying 83.1% (64 of 77) and 80% (8 of 10) to the species and complex levels, respectively, and 94.3% (82 of 87) to the genus level, we show that an approach using routine sample preparation, an up-to-date commercial database minimally augmented with custom spectra, and testing at an early stage of growth is promising.
