Determination of origin of 2 Vibrio cholerae strains isolated on the territory of Rostov region by using full genome sequencing data. Materials and methods. Toxigenic strain 2011EL-301 V. cholerae O1 El Tor Inaba No. 301 (ctxAB+, tcpA+) and nontoxigenic strain V. cholerae О1 Ogawa P-18785 (ctxAB-, tcpA+) were studied. Sequencing was carried out on the MiSeq platform. Phylogenetic analysis of the genomes obtained was carried out based on comparison of conservative part of the studied and 54 previously sequenced genomes. Results. 2011EL-301 strain genome was presented by 164 contigs with an average coverage of100, N50 parameter was 132 kb, for strain P-18785 - 159 contigs with a coverage of69, N50 - 83 kb. The contigs obtained for strain 2011EL-301 were deposited in DDBJ/EMBL/GenBank databases with access code AJFN02000000, for strain P-18785 - ANHS00000000. 716 protein-coding orthologous genes were detected. Based on phylogenetic analysis strain P-18785 belongs to PG-1 subgroup (a group of predecessor strains of the 7 th pandemic). Strain 2011EL-301 belongs to groups of strains of the 7 th pandemic and is included into the cluster with later isolates that are associated with cases of cholera in South Africa and cases of import of cholera to the USA from Pakistan. Conclusion. The data obtained allows to establish phylogenetic connections with V. cholerae strains isolated earlier.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Определение происхождения двух штаммов Vibrio cholerae, выделенных на территории Ростовской области, с использованием данных полногеномного секвенирования. Материалы и методы. Исследовали токсигенный штамм 2011EL-301 - V. cholerae O1 Эль-Тор Inaba №301 (ctxAB+, tcpA+) и нетоксигенный штамм V. cholerae О1 Ogawa P-18785 (ctxAB -, tcpA+). Секвенирование проводили на платформе MiSeq. Филогенетический анализ полученных геномов проведен на основе сравнения консервативной части исследуемых и ранее секвенированных 54 геномов. Результаты. Геном штамма 2011EL-301 был представлен 164 контигами со средним покрытием 100, показатель N50 составил 132 тыс. п.о., для штамма P-18785-159 контигами с покрытием 69, N50 - 83 тыс. п.о. Полученные контиги для штамма 2011EL-301 депонированы в базах данных DDBJ/EMBL/GenBank с номером доступа AJFN02000000, для штамма P-18785 - ANHS00000000. Было выявлено 716 белок-кодирующих ортологичных генов. По результатам филогенетического анализа штамм P-18785 относится к субгруппе PG-1 (группа штаммов-предшественников 7 пандемии). Штамм 2011EL-301 относится к группе штаммов 7 пандемии и включается в кластер с поздними изолятами, которые ассоциированы со случаями холеры в ЮАР и случаями заноса холеры в США из Пакистана. Заключение. Полученные данные позволили установить филогенетические связи с ранее выделенными штаммами V. cholerae.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Vibrio cholerae</kwd><kwd>Vibrio cholerae</kwd><kwd>full genome sequencing</kwd><kwd>Vibrio cholerae comparative genomics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>полногеномное секвенирование</kwd><kwd>сравнительная геномика Vibrio cholerae</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ломов Ю.
