An attempt to use MALDI-TOF mass-spectrometry method for identification of leptospiral isolates on the serovar level. Materials and methods. 8 reference Leptospira spp. and 11 leptospira strains isolated from leptospiral patients and infected animals in the North-VNfestem region of Russia were included into the study. Mass-spectra of all the studied strains were obtained by direct profiling of cell extracts. The created main spectral profiles (MSP) of reference strains were used for identification of isolates. Evaluation of identification was carried out by calculating coefficients of matching rate of separate spectra of each isolate with MSP of all the reference strains. Results. Results of identification have shown the similarity of spectra of isolates belonging to Pomona, Icterohaemorrhagiae and Canicola serogroups, with MSP of saprophyte strain L. biflexa Patoc I. It is assumed that spectra of the studied strains contained peaks of polysaccharide O-antigens. Wherein maximum mean values of matching rate coefficients between spectra of isolates and MSP of pathogenic reference strains of leptospira correctly matched serovar type of the isolate. Conclusion. Further extended studies may form the base of development of a simple and rapid method of typing of leptospirosis causative agents on the level of serovars using MALDI-TOF mass-spectrometry.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Попытка использования метода MALD1-TOF масс-спектрометриидля идентификации изолятов лептоспир на уровне сероваров. Материалы и методы. В исследование были включены 8 референсных штаммов Leptospira spp. и 11 штаммов лептоспир, выделенных от больных лептоспирозом и инфицированных животных в Северо-Западном регионе России. Масс-спектры всех исследуемых штаммов получали прямым профилированием клеточных экстрактов. Созданные главные спектральные профили (MSP) референсных штаммов использовали для идентификации изолятов. Оценку идентификации осуществляли путем вычисления коэффициентов совпадения отдельных спектров каждого изолята с MSP всех референсных штаммов. Результаты. Результаты идентификации показали схожесть спектров изолятов, относящихся к серогруппам Pomona, Ictero-haemorrhagiae и Canicola, с MSP сапрофитного штамма L. biflexa Patoc I. Предполагается, что спектры исследуемых штаммов содержали в своем составе пики полисахаридных О-антигенов. При этом максимальные средние значения коэффициентов совпадения между спектрами изолятов и MSP патогенных референсных штаммов лептоспир правильно совпадали с типом серовара изолята. Заключение. Дальнейшие расширенные исследования могут быть положены в основу разработки быстрого и простого метода типирования возбудителей лептоспироза на уровне сероваров с использованием MALDI-TOF масс-спектрометрии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Leptospira spp</kwd><kwd>MALDI-TOF масс-спекгрометрия</kwd><kwd>serotyping</kwd><kwd>serovars</kwd><kwd>MALDI-TOF mass-spectrometry</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>серотипирование</kwd><kwd>серовары</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ананьина Ю.В.
