Поэтому актуальной задачей представляется выявление причин этих отклонений путем изучения структуры генетических детерминант, ответственных за синтез О-антигена (wb* кластеров). Цель работы – идентификация wb* кластеров в геномах Vibrio cholerae R-варианта, изучение их структуры и проведение филогенетического анализа данных штаммов. Материалы и методы. Проведено полногеномное секвенирование (платформы Illumina MiSeq и MinION). Cборка осуществлялась de novo программой-сборщиком SPAdes (v.3.11.1). Манипуляции с последовательностями кластеров и визуализация данных проводились с помощью программы BLAST из пакета ncbi-blast-suite версии 2.13.0, скриптов на языке Python и пакетов pyGenomeViz, Biopython. Филогенетическое дерево построено с использованием программы roary (v.3.13.0). Полногеномное выравнивание проводилось программами nucmer и promer из пакета MUMmer 4 версии 4.0. Результаты и обсуждение. У штаммов холерного вибриона R-варианта установлено наличие в геноме wb* кластеров разных типов, среди которых наиболее часто встречались О23 и О59. Проведено сравнение транслированных аминокислотных последовательностей wb* регионов штаммов R-варианта с аминокислотными последовательностями представленных в базе данных NCBI референсных штаммов. Часть рассмотренных кластеров полностью совпадала с референсными. Для других установлена высокая вариабельность. Филогенетически штаммы группировались преимущественно в соответствии с типом wb* кластера, вне зависимости от S/R-фенотипа. Штаммы V. cholerae R-варианта сложно систематизировать по признаку агглютинабельности, и для определения их патогенного потенциала необходимо использовать молекулярные методы исследования, в частности полимеразную цепную реакцию.</p></abstract><trans-abstract xml:lang="en"><p>Cholera vibrios, isolated from surface water bodies during monitoring activities, can differ from typical ones in terms of agglutinability with diagnostic cholera sera, which makes it difficult to assign them to a specific serogroup. Therefore, the determination of the causes for these deviations through the study of the structure of genetic determinants responsible for the synthesis of O‑antigen (wb* clusters) is considered a relevant task. The aim of this work was to identify wb* clusters in the genomes of R-variant Vibrio cholerae, study their structure, and conduct phylogenetic analysis of the strains. Materials and methods. Full genome sequencing was performed using Illumina MiSeq and MinION platforms. The assembly was conducted de novo using the SPAdes assembler software (v.3.11.1). Manipulation of cluster sequences and data visualization were carried out using the BLAST program from the ncbi-blast-suite package version 2.13.0, Python scripts and packages such as pyGenomeViz and Biopython. The phylogenetic tree was constructed using the roary program (v.3.13.0). Full genome alignment was carried out using the nucmer and promer programs from the MUMmer 4 package version 4.0. Results and discussion. R-variant V. cholerae contains different types of wb* clusters in the genome, with most commonly occurring O23 and O59. A comparison has been made between translated amino acid sequences of wb* regions in R-variant strains and amino acid sequences of reference strains present in the NCBI database. Some of the analyzed clusters completely match with reference strains, while others show high variability. Phylogenetically, the strains primarily group together according to the wb* cluster type, regardless of the S/R phenotype. Classifying R-variant V. cholerae strains based on agglutinability is challenging. Molecular research methods, polymerase chain reaction, in particular, are necessary to determine the pathogenic potential of such strains.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Vibrio cholerae</kwd><kwd>R-вариант</kwd><kwd>wb* кластер</kwd><kwd>серогруппа</kwd><kwd>wbe</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Vibrio cholerae</kwd><kwd>R-variant</kwd><kwd>wb* cluster</kwd><kwd>serogroup</kwd><kwd>wbe</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">Левченко Д.А., Кругликов В.Д., Архангельская И.В., Якушева О.А., Алексеева Л.П., Водопьянов С.О., Ежова М.И., Носков А.К.
