Цель настоящего исследования состояла в определении методом иммуноферментного анализа (ИФА) уровня антител к антигенам чумного микроба в сыворотках морских свинок, выживших после заражения сублетальными дозами вирулентных штаммов чумного микроба. Материалы и методы. Морских свинок заражали подкожно штаммом дикого типа Y. pestis subsp. pestis 231 или бескапсульным (Caf1–) штаммом Y. Pestis subsp. pestis 358/12 в дозе 30 КОЕ . Кровь от больных или переболевших чумой морских свинок отбирали на 15, 30, 60 и 90-е сутки после заражения. Антительный ответ определяли к 18 рекомбинантным белкам Y. pestis методом ИФА. Результаты и обсуждение. У морских свинок наблюдали неоднородный антительный ответ к большинству антигенов с вариацией титров IgG от животного к животному. После введения штаммов Y. pestis 231 и Y. pestis 358/12 иммунодоминантный характер имели 6 (AilC, Caf1, Pla, YapM, YapL, TalB) и 6 (AilC, pH6, SurA, YapM, MetQ, HtpG) из 18 использованных белков соответственно. Для большинства исследуемых антигенов наблюдали подъем титров антител в сыворотках морских свинок, зараженных штаммом дикого типа Y. pestis 231, к 90-м суткам наблюдения, в то время как при заражении бескапсульным (Caf1–) штаммом Y. pestis subsp. Pestis 358/12 обнаружили тенденцию снижения титров специфических антител к 90-м суткам. Сохранение в организме морских свинок в течение длительного времени после перенесенного заболевания антител к белкам Y. pestis разной локализации, функциональной активности, степени представленности на поверхности бактериальной клетки свидетельствует о множественном характере формирования иммунного ответа при чуме. Полученные результаты важны для дизайна эффективных вакцин против чумы, а также для поиска новых мишеней для диагностики данной инфекции.</p></abstract><trans-abstract xml:lang="en"><p>Designing of new means for the specific prevention of plague, especially protein subunit vaccines, is impossible without studying the role of individual antigens in the manifestation of the pathogenic and immunogenic properties of Yersinia pestis. The aim of the present study was to determine the antibody levels to Y. pestis antigens in guinea pigs that survived infection with sub-lethal doses of virulent plague agent strains using enzyme immunoassay (ELISA). Materials and methods. Guinea pigs were inoculated subcutaneously with 30 CFU of the wild type Y. pestis subsp. Pestis strain 231 or non-capsular Y. pestis subsp. pestis Caf1-negative strain 358/12. Blood samples from sick or recovered guinea pigs were collected on day 15, 30, 60, and 90 after infection. The antibody response was assessed by 18 recombinant Y. pestis proteins in ELISA. Results and discussion. Heterogeneity of the antibody responses to the majority of the antigens with variation of IgG titers from animal to animal has been revealed. We observed increase in antibody titers by day 90 for the most analyzed antigens in the sera of the guinea pigs injected with wild type Y. pestis 231. On the contrary we found reduction in antibody titers by day 90 in case of inoculation with Y. pestis 358/12. The preservation of antibodies to Y. pestis proteins of different localization in the organism of the guinea pigs, as well functional activity, and the degree of representation on the surface of bacterial cell for a prolonged period of time indicates the multiplex nature of the plague immunity formation. Our ﬁndings are significant for the future design and development of effective vaccines against plague and the search for new targets for diagnostics of this disease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Yersinia pestis</kwd><kwd>бубонная чума</kwd><kwd>рекомбинантные антигены</kwd><kwd>антитела</kwd><kwd>иммунный ответ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Yersinia pestis</kwd><kwd>bubonic plague</kwd><kwd>recombinant antigens</kwd><kwd>antibodies</kwd><kwd>immune response</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках отраслевой научно- исследовательской программы Роспотребнадзора на 2021–2025 гг. «Проблемно-ориентированные на‑ учные исследования в области эпидемиологического надзора за инфекционными и паразитарными бо‑ лезнями».</funding-statement><funding-statement xml:lang="en">The work was carried out within the frames of the sectoral research program of the Rospotrebnadzor for 2021–2025 “Problem-Oriented Scientific Research in the Field of Epidemiological Surveillance of Infectious and Parasitic Diseases”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Попов Н.В., Ерошенко Г.А., Карнаухов И.Г., Кузнецов А.А., Матросов А.Н., Иванова А.В., Поршаков А.М., Ляпин М.Н., Корзун В.М., Вержуцкий Д.Б., Аязбаев Т.З., Лопатин А.А., Ашибоков У.М., Балахонов С.В., Куличенко А.Н., Кутырев В.В.
