Сочетание культуральных и молекулярно-генетических методик позволяет полноценно оценить спектр микробиоты. Цель исследования – оценить характер микробиоты толстой кишки у молодых здоровых жителей г. Архангельска. Исследованы фекалии здоровых жителей г. Архангельска (n = 43). Анализ характера микробиоты проводили культуральным методом и полимеразной цепной реакцией (ПЦР) с определением 33 показателей. По данным ПЦР у 100 % обследуемых отмечали дефицит лактобактерий, Roseburia inulinivorans – 20,9 %, Blautia spp. – 72,1 %, Agathobacter rectalis – 37,2 %, E. coli – 60,46 %, а также избыток Fusobacterium nucleatum – в 16,28 % случаев, Streptococcus spp. – 13,95 %, Acinetobacter spp. – 6,97 %, условнопатогенных представителей порядка Enterobacteriales – в 32,58 %. По результатам культурального метода исследования регистрировали дефицит лактобактерий в 97,67 % случаев, энтерококков – 51,16 %, бактероидов – 27,91 %, типичной (лактоза+) Е. coli – 72,09 %, бифидобактерий – 13,95 %, а также выявление избытка Klebsiella spp. – в 32,58 %, Staphylococcus aureus – 4,65 %. Среднее количество лактобактерии, зарегистрированных культуральным методом составило 4,81 lg КОЕ/г, энтерококков – 5,0 lg КОЕ/г, S. aureus – 5,12 lg КОЕ/г, К. Pneumonia – 4,75 lg КОЕ/г, К. oxytoca – 5,62 lg КОЕ/г, Е. coli – 6,52 lg КОЕ/г, Bifidobacterium spp. – 9,0 lg КОЕ/г, Васteroides spp. – 9,0 lg КОЕ/г. Статистически значимые различия в определении микроорганизмов были обнаружены в отношении Lactobacillus spp., Enterococcus spp., Bifidobacterium spp., Bacteroides spp. (p &lt; 0,001). Таким образом, культуральным и молекулярно-генетическим методами исследования нами выявлен дисбаланс микробиоты толстой кишки у здоровых жителей г. Архангельска.</p></abstract><trans-abstract xml:lang="en"><p>The study of the biodiversity of the colon microbiota in residents of the Arctic regions is currently of particular interest. The combination of cultural and molecular genetic methods allows for a comprehensive assessment of the microbiota spectrum. Purpose of the study – to assess the colon microbiota in young, healthy residents of Arkhangelsk. The material for the study was feces from healthy residents (n = 43). Analysis of the nature of the microbiota was carried out using cultural methods and PCR with the determination of 33 indicators. Research results. According to PCR data, 100 % of the subjects had a deficiency of lactobacilli; Roseburia inulinivorans was present in 20.9 %, Blautia spp. in 72.1 %, Agathobacter rectalis in 37.2 %, E. coli in 60.46 %, and there was an excess of Fusobacterium nucleatum in 16.28% of cases, Streptococcus spp. in 13.95 %, Acinetobacter spp. in 6.97 %, and opportunistic representatives of the order Enterobacteriales in 32.58 %. According to the results of the cultural research method, a deficiency of lactobacilli was recorded in 97.67 % of cases, enterococci in 51.16 %, Bacteroides in 27.91 %, typical (lactose +) E. coli in 72.09 %, bifidobacteria in 13.95 %, as well as detection of an excess of Klebsiella spp. in 32.58 % and Staphylococcus aureus in 4.65%. The average amount of lactobacilli by the cultural method was 4.81 lg CFU/g, Enterococci 5.0 lg CFU/g, S. aureus 5.12 lg CFU/g, K. pneumoniae 4.75 lg CFU/g, K. oxytoca 5.62 lg CFU/g, E. coli 6.52 lg CFU/g, Bifidobacterium spp. 9.0 lg CFU/g, and Bacteroides spp. 9.0 lg CFU/g. Statistically significant differences in the identification of microorganisms were found for Lactobacillus spp., Enterococcus spp., Bifidobacterium spp., and Bacteroides spp. (p &lt; 0.001). An imbalance of the colon microbiota in healthy residents of Arkhangelsk was revealed through cultural and molecular genetic research methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>культуральный метод</kwd><kwd>полимеразная цепная реакция</kwd><kwd>микробиота толстой кишки</kwd><kwd>северный регион</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cultural method</kwd><kwd>molecular genetic method</kwd><kwd>colon microbiota</kwd><kwd>northern region</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана грантом в рамках конкурса на лучшие проекты молодых ученых по приоритетным направлениям научного и инновационного развития ФГБОУ ВО СГМУ в 2022 году.</funding-statement><funding-statement xml:lang="en">The work was supported by a grant as part of a competition for the best projects of young scientists in priority areas of scientific and innovative development of the FSBEI HE MSMU in 2022.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Beam A., Clinger E., Hao L.
