The use of genomic approaches allows a detailed studying of the pathogenetic potential of H. pylori bacteria. The aim of the study. To investigate the genome structural and functional organization of the H. pylori isolated in the Republic of Belarus. Methods. Using next-generation sequencing with the Ion PGM System genome analyzer, a genomic analysis of the clinically significant H. pylori isolate was performed. Results. The study of the structural and functional organization of the H. pylori HP42K isolate genome can identify the pathogenetic and antigenic determinants as possible predictors of the clinical properties. The loci: five DNA motifs AATAAAGATA and EPIYA-ABC motifs in the structure of the cagA gene, as well as the oipA gene, and alleles s1 and m1a of the vacA gene were identified to be not related to carcinogenesis. Three circular sequences represented by chromosomal and plasmid DNA of H. pylori were identified and deposited in GenBank NCBI with identification numbers CP034314.1, CP034313.1, and CP034312.1. Conclusion. The analysis of the H. pylori HP42K isolate genome showed its pathogenetic features to be associated with the development of gastroduodenal pathology but not associated with stomach cancer risk.</p></abstract><trans-abstract xml:lang="ru"><p>Введение. Использование геномных подходов позволяет подробно изучить патогенетический потенциал бактерии Helicobacter pylori. Цель. Исследовать структурно-функциональную организацию генома H. pylori, изолированного в Республике Беларусь. Методы. С использованием высокопроизводительного секвенирования на базе геномного анализатора Ion PGM System проведен геномный анализ клинически значимого изолята Н. pylori. Результаты. Изучение структурной и функциональной организации генома изолята H. pylori HP42Kможет выявить патогенетические и антигенные детерминанты, позволяющие прогнозировать его клинические свойства. Установлено наличие локусов, не связанных с канцерогенезом: 5 ДНК-мотивов AATAAGATA и EPIYA-ABC мотив в структуре cagA гена, а также выявление oipA гена, и аллелей s1 и m1a гена vacА. Идентифицированы 3 кольцевые последовательности, представленные хромосомной и плазмидными ДНКH.pylori, которые депонированы в GenBank NCBI с идентификационными номерами CP034314.1, CP034313.1 и CP034312.1. Заключение. Анализ генома изолята H. pylori HP42K показал, что его патогенетические особенности ассоциированы с развитием гастродуоденальной патологии и не связаны с канцерогенными эффектами.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Ion Torrent</kwd><kwd>Helicobacter pylori</kwd><kwd>plasmids</kwd><kwd>next-generation sequencing</kwd><kwd>Ion Torrent</kwd><kwd>structural and functional organization of the genome</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Нєlicobacterpylori</kwd><kwd>плазмиды</kwd><kwd>высокопроизводительное секвенирование</kwd><kwd>структурно-функциональная организация генома</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Marshall B.J., Warren J.R.
