National program «Elimination of measles and rubella and achievement of a stable sporadic incidence of epidemic mumps in the Russian Federation (2021–2025)» sets the aim of gradual integration of mumps surveillance into the existing measles and rubella surveillance system. One of the key components of surveillance system is a laboratory confirmation of mumps cases. There are two approaches for laboratory confirmation of mumps cases, based on serological or molecular genetic methods. The aim of the work is molecular genetic characteristic of the mumps viruses (MuVs) circulated in the Russian Federation in 2022.</p> <p><bold>Materials and methods. </bold>Samples of swabs from the inner surface of the cheek of 11 patients with mumps were collected for the study. Viral RNA was isolated directly from the samples. The isolated RNA was used as a matrix for RT-PCR. PCR products were sequenced using the Sanger method, and phylogenetic analysis was performed using the MEGA-X software.</p> <p><bold>Results.</bold> The MuV genotype G was detected in all samples. Phylogenetic analysis showed the presence of two virus genetic groups G-1 and G-2 that were significantly different from the viruses circulating in other countries.</p> <p><bold>Conclusion.</bold> The identification of two MuV genetic groups in a limited area suggests a high genetic diversity of the pathogen.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Эпидемический паротит (ЭП) – вирусное заболевание, имеющее высокую социальную значимость. Национальная программа «Элиминация кори и краснухи, достижение устойчивой спорадической заболеваемости эпидемическим паротитом в Российской Федерации (2021–2025 гг.)» ставит цель постепенной интеграции надзора за ЭП в существующую систему надзора за корью и краснухой. Одним из ключевых компонентов надзора является лабораторное подтверждение случаев ЭП. В настоящее время существует два подхода к лабораторной верификации ЭП – серологический и молекулярно-генетический.</p> <p><bold>Цель работы </bold>– молекулярно-генетическая характеристика вирусов ЭП (ВЭП), циркулировавших в Российской Федерации в 2022 г.</p> <p><bold>Материалы и методы. </bold>Для исследования были взяты образцы соскоба с внутренней поверхности щеки у 11 больных ЭП. Вирусная РНК была выделена напрямую из образцов и использована в качестве матрицы для ОТ-ПЦР. Было проведено секвенирование ПЦР-продуктов по методу Сенгера, проведён филогенетический анализ в программе MEGA-X.</p> <p><bold>Результаты.</bold> У всех обследованных выявлен ВЭП, принадлежащий генотипу G. Филогенетический анализ показал наличие двух геногрупп вируса – G-1 и G-2, существенно отличающихся от вирусов, циркулировавших в других странах.</p> <p><bold>Заключение.</bold> Выявление двух генетических групп ВЭП на ограниченной территории позволяет предполагать высокое генетическое разнообразие патогена.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mumps virus</kwd><kwd>genotype</kwd><kwd>sequencing</kwd><kwd>phylogenetic analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вирус эпидемического паротита</kwd><kwd>генотип</kwd><kwd>секвенирование</kwd><kwd>филогенетический анализ</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Исследование выполнено за счет государственного бюджета.</institution></institution-wrap><institution-wrap><institution xml:lang="en">The research was funded by the state budget.</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">National Program «Elimination of measles and rubella and achievement of a stable sporadic incidence of epidemic mumps in the Russian Federation (2021–2025).
