Разработка эффективных и безопасных вакцин для профилактики коклюша остается актуальной задачей здравоохранения.</p></sec><sec><title>Цель</title><p>Цель. Изучение протективной активности и безопасности бесклеточных коклюшных вакцин (БКВ), содержащих комплекс протективных антигенов из свежевыделенных и вакцинных штаммов Вordetella pertussis.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для изготовления БКВ использованы свежевыделенные (№ 287, и № 317) и вакцинные (№ 305 и № 475) штаммы В. pertussis с «невакцинным» и «вакцинным» аллельными вариантами гена субъединицы А коклюшного токсина (КТ), гена промотора КТ, гена пертактина, гена фимбрий 2 и гена фимбрий 3.</p></sec><sec><title>Результаты</title><p>Результаты. Все исследованные варианты БКВ были безвредны в тесте изменения массы тела мышей и чувствительности к гистамину. Протективная активность БКВ3 (штаммы № 287, № 317 и № 305) и БКВ1 (штаммы № 287, № 305 и № 475) была выше, чем у БКВ2 (штаммы № 317, № 305 и № 475). Титры IgG к КТ также были выше у мышей, иммунизированных БКВ1 и БКВ3.</p></sec><sec><title>Заключение</title><p>Заключение. Более высокая протективная активность БКВ3 и БКВ1 может быть связана с генотипом штамма № 287, имеющего промотор КТ ptxP3 и отличающегося повышенным уровнем продукции КТ и высокой вирулентностью. Наиболее перспективной для дальнейших доклинических и клинических исследований представляется БКВ3, имеющая в своем составе 2/3 антигенов штаммов доминирующего «невакцинного» генотипа и 1/3 «вакцинного» генотипа, в целом соответствующих по генам КТ, пертактина и фимбрий, циркулирующим в настоящее время штаммам В. pertussis.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. The development of effective and safe vaccines for pertussis prevention remains an urgent public health challenge.</p></sec><sec><title>Aim</title><p>Aim. To study the protective activity and safety of acellular pertussis vaccine (AcPV) containing a complex of protective antigens from freshly isolated and vaccine strains of Bordetella pertussis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Freshly isolated (No. 287, and No. 317) and vaccine (No. 305 and No. 475) B. pertussis strains with «non-vaccine» and «vaccine» allelic variants of the pertussis toxin (PT) subunit A gene, the PT promoter gene, the pertactin gene, the fimbria 2 gene, and the fimbria 3 gene strains were used for the production of AcPV.</p></sec><sec><title>Results</title><p>Results. All the studied variants of AcPV were harmless in the test of changes in the body weight of mice and sensitivity to histamine. The protective activity of AcPV3 (strains No. 287, No. 317 and No. 305) and AcPV1 (strains No. 287, No. 305 and No. 475) was higher than that of AcPV2 (strains No. 317, No. 305, and No. 475). IgG antibody titers to PT were also higher in mice immunized with AcPV1 and AcPV3.</p></sec><sec><title>Conclusion</title><p>Conclusion. The higher protective activity of AcPV3 and AcPV1 may be associated with the genotype of strain No. 287, which has a ptxP3 PT promoter and is characterized by an increased level of PT production and high virulence. The most promising for further preclinical and clinical studies is AcPV3, which contains 2/3 of the antigens of the dominant «non-vaccine» genotype and 1/3 of the «vaccine» genotype, corresponding to the genes of PT, pertactin and fimbria to the currently circulating B. pertussis strains.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>штаммы B. pertussis</kwd><kwd>генотип</kwd><kwd>бесклеточная коклюшная вакцина</kwd><kwd>протективные свойства</kwd><kwd>токсичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>B. pertussis strains</kwd><kwd>genotype</kwd><kwd>acellular pertussis vaccine</kwd><kwd>protective properties</kwd><kwd>toxicity No conflict of interest to declare</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">Yeung K.H.T., Duclos P., Nelson EAS, et al.
