Материалы и методы. В работе использовали штаммы V. cholerae серогрупп О1 и О139, из которых были получены препараты OMV. Методом трансмиссионной электронной микроскопии (ТЭМ) изучали строение препаратов OMV. Полногеномное секвенирование ДНК проводили на платформе MiSeq. Нуклеотидные и соответствующие аминокислотные последовательности генов изучали c помощью биоинформационного анализа. Белковое профилирование проводили с помощью MALDI-TOF масс-спектрометрии. Ферментативные активности детектировали с использованием соответствующих сред и субстратов. Определение (поверхностных детерминант) липополисахарида (ЛПС) и белков наружной мембраны в составе OMV осуществляли методом иммуноферментного анализа. Анализ спектра жирных кислот (ЖК) проводили методом газожидкостной хроматографии масс-спектрометрии. Результаты и обсуждение. Получены препараты OMV из атоксигенных штаммов холерных вибрионов. ТЭМ выявлено, что OMV представлены структурами сферической формы около 40–200 нм. По данным полногеномного секвенирования установлено, что в составе OMV обнаружены фрагменты хромосом, содержащие гены штаммов V. cholerae серогрупп O1 и O139, из которых они выделены. Проведенный биоинформационный анализ выявил отличия в структуре гена ompT у исходных штаммов и у OMV, полученных из штаммов V. cholerae серогрупп O1 и O139. Ген ∆ompT препарата OMV V. cholerae O139-серогруппы был трункирован и образовывал пептид в 17 аминокислотных остатков (-LENHHQKNREPDKEFPY-). Анализ композиционного состава OMV выявил наличие в их составе ферментов (N-ацетил-β-D-глюкозаминидазы и ДНК-азы), белков наружных мембран (OmpT и OmpU), ЛПС, насыщенных, сis/trans-изомеров ненасыщенных ЖК и разветвленных ЖК. Обнаружены различия в композиционном составе OMV, полученных из атоксигенных штаммов V. cholerae серогрупп О1 и О139.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the work was to study the composition of vesicle preparations (OMV) in Vibrio cholerae strains O1 El Tor (ctxAB– tcpA– ; ctxAB– tcpA+ ) and O139 (ctxAB– tcpA– ) isolated from various sources. Materials and methods. V. cholerae strains O1 and O139 serogroups were used in the work, from which OMV preparations were obtained. The structure of OMV preparations was studied by transmission electron microscopy (TEM). Genome-wide DNA sequencing was performed on the MiSeq platform. The nucleotide and corresponding amino acid sequences of the genes were studied using bioinformatics analysis. Protein profiling was conducted using MALDI-TOF mass spectrometry. Enzymatic activities were detected using appropriate media and substrates. Determination of (surface determinants) lipopolysaccharide (LPS) and outer membrane proteins in the composition of OMV was carried out by enzyme immunoassay (ELISA). The analysis of the spectrum of fatty acids was performed by gas-liquid chromatography mass spectrometry. Results and discussion. OMV preparations have been obtained from non-toxigenic strains of cholera vibrios. TEM has revealed that OMVs are represented by spherical structures of about 40–200 nm. Genome-wide sequencing has shown that fragments of chromosomes containing genes of V. cholerae strains, O1 and O139 serogroups, from which they were isolated are present in the OMV. The bioinformatic analysis revealed differences in the structure of the ompT gene in the initial strains and in OMV obtained from V. cholerae strains O1 and O139 serogroups. The ΔompT gene of the OMV preparation from V. cholerae O139 serogroup was trunked and formed a peptide of 17 amino acid residues (-LENHHQKNREPDKEFPY-). Analysis of the OMV composition has revealed the presence of enzymes (N-acetyl-β-D-glucosaminidase and DNAazes), proteins of outer membranes (ompT and OmpU), LPS, saturated, сis/trans isomers of unsaturated fatty acids and branched fatty acids. Differences in the composition of OMV obtained from non-toxigenic strains of V. cholerae O1 and O139 serogroups have been identified.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>холерный вибрион</kwd><kwd>композиционный состав везикул (OMV)</kwd><kwd>ЛПС</kwd><kwd>ОmpT</kwd><kwd>ОmpU</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cholerae vibrio</kwd><kwd>vesicle composition (OMV)</kwd><kwd>LPS</kwd><kwd>OmpT</kwd><kwd>OmpU</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">Луста К.А.
