Application of MALDI Mass-Spectrometry for Diagnostics of Particularly Dangerous Infectious Diseases: Current State of Affairs and Prospects
Year: 2014
Type: article
Abstract: Mass spectrometry is a modern physical-chemical analytical method that provides for qualitative and quantitative assessment of the substance composition. It is based on pre-ionization of the atoms and molecules included into it. One of the advanced methods of ionization, due to which mass-spectrometry investigation of macromolecules has become a frequent practice, is matrix-assisted laser desorption/ionization (MALDI). The essence of it is the pulsed laser irradiation of the matter under study, mixed with the matrix. The review discusses current data on MALDI mass-spectrometry application for the performance of species-specific and genus-specific identification of microorganisms at the premises of diagnostic laboratories. Considered are the basic advantages of MALDI-TOF identification as compared to bacteriologic, immunologic, and molecular-genetic methods of assessment. Allocated is the mass-spectrometry position in the system of laboratory diagnostics of infectious diseases, including particularly dangerous ones, in the territory of the Russian Federation.
