Экспериментально подтверждено, что предлагаемый подход для дифференциации протеотипов штаммов B. anthracis с индексом дискриминации 0,952 превышает таковой для метода canSNP-типирования и сопоставим с индексом дискриминации для метода MLVA31. Корреляция результатов кластеризации штаммов при типировании методами MALDI-TOF масс-спектрометрии и canSNP-генотипирования достигает 95 % в отношении разделения на главные генетические линии A и B. Изученные штаммы сибиреязвенного микроба, относящиеся в большинстве случаев к филогенетическим группам линии А, представляют собой более десятка белковых профилей, что может быть связано с различиями в уровне экспрессии белков у штаммов каждого canSNP-генотипа. MALDI-TOF масс-спектрометрия позволяет получить сопоставимые с генетическими тестами результаты, имеет лучшую дискриминирующую способность по сравнению с canSNP-типированием, более проста в выполнении.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the work was to compare the discriminating capacity of the canSNP13 genotyping and MALDI‑TOF mass spectrometry methods based on the results of the study of anthrax pathogen strains belonging to the two main genetic lines A and B.</p><sec><title>Materials and methods</title><p>Materials and methods. 73 Bacillus anthracis strains from the collection of microorganisms of the Stavropol Research Anti-Plague Institute of the Rospotrebnadzor were investigated.

It has been experimentally confirmed that the proposed approach for differentiating proteotypes of B. anthracis strains with a discrimination index of 0.952 exceeds the one for the canSNP typing method and is comparable to the discrimination index for the MLVA31 method. The correlation of the results of strain clustering during typing by MALDI-TOF mass spectrometry and canSNP genotyping reaches 95 % as regards the division into the main genetic lines A and B. The studied strains of anthrax microbe, which mostly fall under phylogenetic groups of lineage A, represent more than a dozen protein profiles, which may be due to differences in the level of protein expression in strains of each canSNP genotype. MALDI-TOF mass spectrometry makes it possible to obtain the results comparable with genetic tests, has a better discriminating capacity compared to canSNP typing, and is easier to perform.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Bacillus anthracis</kwd><kwd>MALDI-TOF MS</kwd><kwd>белковое профилирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Bacillus anthracis</kwd><kwd>MALDI-TOF MS</kwd><kwd>protein profiling</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Shadomy S., El Idrissi A., Raizman E., Bruni M., Palamara E., Pittiglio C., Lubroth J.
