Comparison of protein profiles obtained by matrix-assisted laser desorption/ionization–Time-of-flight mass spectrometry in representatives of the family Mycobacteriaceae grown on various nutrient media
Background: The nutrient medium effects on the quality of the matrix-assisted laser desorption/ionization–time-of-flight (MALDI-ToF) mass spectra. The standard library includes spectra of microorganisms of the family Mycobacteriaceae grown on the Lowenstein–Jensen and Middlebrook Media. There are ne...

| description | Background: The nutrient medium effects on the quality of the matrix-assisted laser desorption/ionization–time-of-flight (MALDI-ToF) mass spectra. The standard library includes spectra of microorganisms of the family Mycobacteriaceae grown on the Lowenstein–Jensen and Middlebrook Media. There are new methods for culturing microorganisms from this group, including inoculation on chromogenic media. Methods: The study included 240 strains of NTM isolated from patients during tuberculosis examination. The inoculation of the biological material was carried out on solid culture media of Lowenstein–Jensen and universal chromogenic media. Identification of bacteria from both types of media was performed by MALDI-ToF mass spectrometry (Bruker Daltonik GmbH, Germany). Analysis of protein spectra was performed. Results: For all strains, the spectra revealed both coinciding peaks (regardless of the cultivation medium) and significant differences, including the complete absence of some peaks depending on the medium. The results of a greater divergence of peaks in mass and intensity were obtained for slow-growing species than for fast-growing species. For all analyzed cultures, the number of peaks in the mass spectra was significantly higher when cultivating on a universal chromogenic medium than on a Lowenstein–Jensen medium. Conclusions: The use for NTM cultivation of a universal chromogenic medium makes it possible to obtain acceptable identification results by MALDI-ToF mass spectrometry using a standard library. |
