До настоящего времени не проводилось детального анализа циркулирующих в разное время вариантов возбудителя на территории Омской области.</p></sec><sec><title>Цель</title><p>Цель. Провести сравнительный анализ разнообразия циркулирующих генетических вариантов вируса SARS-CoV-2 на основе молекулярно­генетических данных, определить генетические линии вируса и время их появления, сравнить полученные данные с данными базы GISAID.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено полногеномное секвенирование 222 первичных и 5 культуральных (пассажи на культурах клеток Vero E6 и СПЭВ) образцов вируса SARS-CoV-2, собранных в Омской области с апреля 2020 г. по февраль 2022 г., на платформах Oxford Nanopore Technologies и Illumina. Генетические линии определяли в Pangolin. Анализ проводили в MEGA7 и BioEdit.</p></sec><sec><title>Результаты</title><p>Результаты. Получено 227 полногеномных последовательностей вируса SARS-CoV-2. В базу данных GISAID загружено 222 генома. Определены линии, к которым относятся образцы, построены филогенетические деревья по различным областям генома вируса SARS-CoV-2, проведены оценка уровня гомологии геновариантов вируса и анализ мутаций в области S-­белка.</p></sec><sec><title>Выводы</title><p>Выводы. По полученным данным можно ориентировочно судить о времени появления того или иного варианта вируса SARS-CoV-2, его закреплении и распространении в популяции, наблюдать редкие мутации и циркуляцию некоторых редких генетических линий вируса. Для оценки возможности значимых географически привязанных изменений генома вируса SARS-CoV-2 в Омской области полученных данных недостаточно. Варианты вируса, циркулирующие в области, группируются в один кластер с идентичными вариантами из других областей или стран. Более выраженную внутрикластерную дифференцировку линий можно наблюдать при анализе области RBD. Ситуация по COVID­-19 в Омской области в целом совпадает с таковой во всей стране и мире. Однако это не исключает параллельного возникновения определённых мутаций на отдалённых друг от друга территориях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. To date, no detailed analysis of the variants of the pathogen circulating at different times on the territory of the Omsk region has been carried out.</p></sec><sec><title>Aim</title><p>Aim. Comparative analysis of the diversity of circulating variants of SARS­CoV­-2 based on molecular genetic data, determine the lines and time of their appearance, compare the data obtained with data from the GISAID database.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Genome­wide sequencing of 222 primary and 5 culture (passages on Vero E6 and SPEV cell cultures) samples of SARS­-CoV­-2 from the Omsk region, collected from April 2020 to February 2022, on Oxford Nanopore Technologies and Illumina platforms, was carried out. Genetic lines were determined in Pangolin. The analysis was performed in MEGA7 and BioEdit.</p></sec><sec><title>Results</title><p>Results. 227 genome­wide SARS­-CoV­-2 sequences were obtained. 222 genomes have been uploaded to the GISAID database. The lines to which the samples belong were determined, phylogenetic trees were constructed for various regions of the SARS-CoV­-2 genome, the levels of virus homology were assessed and mutations in the S­protein region were analyzed.</p></sec><sec><title>Conclusions</title><p>Conclusions. According to the data obtained, it is possible to roughly judge the time of the appearance of a particular variant, its consolidation and distribution in the population, and observe the rare mutations and the circulation of some rare lines. To assess the possibility of significant geographically linked changes in the SARS­-CoV­-2 in the Omsk region, the data obtained are insufficient. Virus variants circulating in the region are grouped into one cluster with identical variants from other regions or countries. A more pronounced intracluster differentiation of the lines can be observed when analyzing the RBD region. The situation with COVID­-19 in the Omsk region generally coincides with that in the whole country and the world. However, this does not exclude the parallel occurrence of certain mutations in remote territories from each other.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID­-19</kwd><kwd>Омская область</kwd><kwd>мониторинг</kwd><kwd>секвенирование SARS­-CoV­-2</kwd><kwd>геноварианты</kwd><kwd>линии SARS-CoV-2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-­19</kwd><kwd>Omsk region</kwd><kwd>monitoring</kwd><kwd>sequencing of SARS­-CoV­-2</kwd><kwd>genovariants</kwd><kwd>SARS­-CoV­-2 lineages</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">Wu F., Zhao S., Yu B., et al.
