С использованием оптимизированных методов проанализирован серотиповой состав пневмококков, выделенных от детей в возрасте до 5 лет с инфекциями верхних дыхательных путей. В период с 2016 по 2021 гг. отмечено снижение частоты серотипов, входящих в 13-валентную конъюгированную пневмококковую вакцину (ПКВ13) с 94,1 до 25,8%, преимущественно за счёт серогруппы 6ABCD и серотипа 19F. Охват циркулирующих у детей серотипов вакцинами ПКВ15 и ПКВ20 составил в 2021 г. 28,1 и 41,6%, соответственно. За период исследования наиболее существенно возросло количество невакцинных серогрупп 11AD и 15AF, а также серотипов, не детектируемых в рамках данного протокола капсульного ПЦР-типирования.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents optimized methods for PCR and sequence typing of Streptococcus pneumoniae. The serotype composition of pneumococci isolated from children under 5 years of age with infections of the upper respiratory tract was analyzed using optimized methods. Between 2016 and 2021, there was a decrease in the frequency of serotypes included in the pneumococcal 13-valent conjugate vaccine (PCV13) from 94.1 to 25.8%, mainly due to the 6ABCD serogroup and the 19F serotype. The coverage of serotypes circulating in children with PCV15 and PCV20 vaccines was 28.1% and 41.6% in 2021, respectively. During the study period, the number of non-vaccine serogroups 11AD and 15AF, as well as serotypes that are not detected under this capsular PCR typing protocol, increased most significantly.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>серотипирование</kwd><kwd>ПЦР</kwd><kwd>секвенирование по Сэнгеру</kwd><kwd>вакцины</kwd><kwd>Streptococcus pneumoniae</kwd></kwd-group><kwd-group xml:lang="en"><kwd>serotyping</kwd><kwd>PCR</kwd><kwd>Sanger sequencing</kwd><kwd>vaccines</kwd><kwd>Streptococcus pneumoniae</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">Simell B., Auranen K., Kayhty H., Goldblatt D., Dagan R, O'Brien K.L. et al.
