Investigation of the features of the protein profiles of the spore and vegetative form of the anthrax microbe by the MALDI-TOF MS method using the resources of the Mass-Up program and the package for the statistical software with open source code R. Materials and methods. Spores and vegetative forms of 32 strains of B. anthracis from the collection of microorganisms of the Stavropol Research Institute for Plague Control, including 8 strains isolated from an outbreak of anthrax in Yamal in 2016. Protein profiling was carried out on the Microflex MALDI-TOF mass spectrometer «Bruker Daltonics». Results. The alternative bioinformational-statistical approach used to analyze the MALDI-TOF mass spectra of the causative agent of anthrax made it possible to differentiate the spores and vegetative forms of the microbe based on the identification of the corresponding groups of biomarkers. Conclusion. A comparison of vegetative and spore cells of typical and atypical strains of anthrax causative agent on the basis of MALDI-TOF MS data was made. It has been experimentally confirmed that the protein profiles of cultures of Bacillus anthracis of the spore and vegetative form differ significantly, and this difference can be used to search for potential markers of each of the forms.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Исследование особенностей белковых профилей споровой и вегетативной форм сибиреязвенного микроба методом MALDI-TOF MS с использованием ресурсов программы Mass-Up и комплекса пакетов для статистического программного обеспечения с открытым исходным кодом R. Материалы и методы. Cпоровая и вегетативная формы 32 штаммов B. anthracis из коллекции микроорганизмов Ставропольского противочумного института, в том числе 8 штаммов, выделенных при вспышке сибирской язвы на Ямале в 2016 году. Белковое профилирование проводили на MALDI-TOF масс-спектрометре Microflex «Bruker Daltonics». Результаты. Используемый альтернативный биоинформационно-статистический подход для анализа MALDI-TOF масс-спектров возбудителя сибирской язвы позволил дифференцировать споровую и вегетативную формы микроба на основании выявления соответствующих групп биомаркеров. Заключение. Проведено сравнение вегетативных и споровых клеток типичных и атипичных штаммов возбудителя сибирской язвы на основании данных MALDI-TOF MS. Экспериментально подтверждено, что белковые профили экстрактов культур сибиреязвенного микроба споровой и вегетативной форм существенно отличаются и это различие можно использовать для поиска потенциальных маркеров каждой из форм.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Bacillus anthracis</kwd><kwd>mass spectrometry</kwd><kwd>protein profiling</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>возбудитель сибирской язвы</kwd><kwd>масс-спектрометрия</kwd><kwd>белковое профилирование</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
