Масс-спектрометрия является современным физико-химическим методом анализа, позволяющим проводить качественный и количественный анализ состава вещества, основанный на предварительной ионизации входящих в его состав атомов или молекул. Одним из новых методов ионизации, благодаря которому масс-спектрометрическое исследование макромолекул получило широкое распространение, является разработанная матрично-активированная лазерная десорбция/ионизация (MALDI), представляющая собой импульсное лазерное облучение исследуемого вещества, смешанного с матрицей. В обзоре представлены современные данные о применении метода MALDI масс-спектрометрии для проведения родо- и видоспецифической идентификации микроорганизмов в практике диагностических лабораторий. Рассмотрены преимущества MALDI-TOF идентификации по сравнению с бактериологическими, иммунологическими и молекулярно-генетическими методами исследования. Обозначено место масс-спектрометрии в системе лабораторной диагностики инфекционных болезней, в том числе особо опасных на территории Российской Федерации.

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.
