Study antigenic and immunogenic activity of a conjugate of synthetic hexasaccharide related to a S. pneumoniae serotype 14 capsule polysaccharide chain fragment with bovine serum albumin (BSA). Materials and methods. Synthetic glucoconjugate based on BSA protein carrier and hexasaccharide ligand reflecting capsule polysaccharide chain fragment was obtained by using squarate method. Natural polysaccharide-protein complex from S. pneumoniae serotype 14 strain was obtained from cultural fluid supernatant by acetone precipitation. IgG titer against hexasaccharide/capsule polysaccharide was determined in antimicrobial sera and sera of mice immunized with glucoconjugate by EIA method. Results. Immunogenic activity of glucoconjugate based on BSA protein carriers and synthetic hexasaccharide reflecting S. pneumoniae serotype 14 capsule protein chain fragment was established. After 2 immunizations antibodies against hexasaccharide ligand and BSA were determined in blood sera of mice. Antibody titers against hexasaccharide exceeded the level in intact mice by 4.2 times. BSA in the conjugate did not have effect on production of antibodies against hexasaccharide. Conclusion. The developed experimental test-system based on synthetic glucoconjugate is useful for evaluation of level of antibodies against S. pneumoniae serotype 14 in infected and, probably, carriers of bacteria.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Изучение антигенной и иммуногенной активности конъюгата синтетического гексасахарида, родственного фрагменту цепи капсульного полисахарида S. pneumoniae серотипа 14, с бычьим сывороточным альбумином (БСА). Материалы и методы. Синтетический гликоконъюгат на основе белка-носителя БСА и гексасахаридного лиганда, отвечающего фрагменту цепи капсульного полисахарида, получали с использованием скваратного метода. Природный полисахаридно-белковый комплекс из штамма S. pneumoniae серотипа 14 получали из супернатанта культуральной жидкости осаждением ацетоном. Титр IgG к гексасахариду/капсульному полисахариду определяли в антимикробных сыворотках и сыворотках мышей, иммунизированных гликоконъюгатом методом ИФА. Результаты. Установлена иммуногенная активность гликоконъюгата на основе белка-носителя БСА и синтетического гексасахарида, отражающего фрагмент цепи капсульного полисахарида S. pneumoniae серотипа 14. После двукратной иммунизации в сыворотке крови мышей определяли антитела к гексасахаридному лиганду и БСА. Титр антител к гексасахариду в 4,2 превышал уровень у интактных мышей. БСА в составе конъюгата не влиял на выработку антител к гексасахариду. Заключение. Разработанная экспериментальная тест-система на основе синтетического гликоконъюгата является пригодной для оценки уровня антител к S. pneumoniae серотипа 14 у зараженных, а возможно, и бактерионосителей.</p></trans-abstract><kwd-group xml:lang="en"><kwd>synthetic hexasaccharide</kwd><kwd>S. pneumoniae serotype 14</kwd><kwd>conjugate</kwd><kwd>bovine serum albumin</kwd><kwd>antibody</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синтетический гексасахарид</kwd><kwd>S. pneumoniae серотипа 14</kwd><kwd>конъюгат</kwd><kwd>бычий сывороточный альбумин</kwd><kwd>антитело</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Курбатова Е.А., Воробьев Д.С., Семенова И.Б. и др.
