Изучены состав бактериального микробиома мокроты, а также частоты хромосомных аберраций в лейкоцитах крови 150 пациентов с диагнозом РЛ и у 104 здоровых доноров. Результаты NGS секвенирования ампликона V3-V4 гена 16S рРНК показали, что мокрота больных РЛ имеет признаки дисбиоза с одновременным увеличением содержания бактерий рода Streptococcus. У больных РЛ и в контроле выявлена прямая связь между частотой аберрантных метафаз в лимфоцитах и содержанием в мокроте представителей рода Streptobacillus. Только у пациентов были положительные корреляции между частотой хромосомных аберраций и содержанием бактерий филума Fusobacteria, родов Bacteroides и Leptotrichia. Полученные результаты свидетельствуют о наличии генотоксического действия ряда бактерий, населяющих дыхательные пути человека. Будущие исследования должны быть направлены на поиск кластогенного потенциала бактерий в составе микробиома кишечника у больных колоректальным раком.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to investigate the relationship between the sputum microbiome composition and the level of chromosome damage in blood leukocytes of lung cancer patients. The bacterial microbiome composition of sputum, as well as the frequencies of chromosomal aberrations in blood leukocytes of 150 patients diagnosed with lung cancer and 104 healthy donors were studied. The results of NGS sequencing of the V3-V4 amplicon of the 16S rRNA gene showed that the sputum of lung cancer patients has signs of dysbiosis with a simultaneous increase in the content of bacteria of the genus Streptococcus. In patients with lung cancer and in the control, a direct relationship was found between the frequency of aberrant metaphases in lymphocytes and the content of representatives of the genus Streptobacillus in sputum. Only in patients were there positive correlations between the frequency of chromosomal aberrations and the content of bacteria of the phylum Fusobacteria, the genera Bacteroides and Leptotrichia. The results obtained indicate the presence of a genotoxic effect of a number of bacteria inhabiting the human respiratory tract. Future studies should be aimed at identifying the clastogenic potential of bacteria within the gut microbiome of colorectal cancer patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мокрота</kwd><kwd>бактериальный микробиом</kwd><kwd>таксономический состав</kwd><kwd>NGS секвенирование</kwd><kwd>рак легких</kwd><kwd>бактериальные генотоксины</kwd><kwd>хромосомные аберрации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sputum</kwd><kwd>bacterial microbiome</kwd><kwd>taxonomic composition</kwd><kwd>NGS sequencing</kwd><kwd>lung cancer</kwd><kwd>bacterial genotoxins</kwd><kwd>chromosomal aberrations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Поддержано грантом РНФ №25-15-20012 и грантом Министерства образования Кузбасса № 02/2025</funding-statement><funding-statement xml:lang="en">Supported by the grant of the Russian Science Foundation No. 25-15-20012 and the grant of the Ministry of Education of Kuzbass No. 02/2025</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">Druzhinin V.G., Matskova L.V., Demenkov P.S., et al.
