This assumption was confirmed by failure in allocation of bacterial strains from the normal bile duct. The paper provides rationale for a phenomenon of the normal biliary microbiota as a separate functional layer which protects a biliary tract from colonization by exogenous microorganisms. We revealed the potential of metagenomic data for prevention of infectious diseases, post-operative complications of reconstructive interventions including bile duct stenting and implantation the tissue-engineered structures exposed to the risks of colonization with pathogenic / exogenous microorganisms. The methods based on preserving homeostasis of normal biliary microbiota ecosystem can be used for prevention of hepatobiliary diseases and treatment of biliary tract inflammatory diseases.</p></abstract><trans-abstract xml:lang="ru"><p>Традиционно считалось, что желчный проток стерилен, а присутствие в желчи микроорганизмов является маркером патологического процесса. Подобное предположение подтверждалось безуспешностью выделения бактериальных штаммов из нормального желчного протока. В настоящей работе приводится обоснование феномена нормальной микробиоты желчевыводящих путей как отдельного слоя, который защищает желчные пути от колонизации экзогенными микроорганизмами. Раскрывается возможное использование метагеномных данных для профилактики инфекционных заболеваний и послеоперационных осложнений при реконструктивных вмешательствах. Методы сохранения гомеостаза экосистемы нормальной билиарной микробиоты могут быть использованы для предотвращения гепатобилиарных заболеваний и лечения воспалительных заболеваний желчевыводящих путей.</p></trans-abstract><kwd-group xml:lang="en"><kwd>biliary microbiota</kwd><kwd>biliary microbiome</kwd><kwd>cholangitis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>билиарная микробиота</kwd><kwd>билиарный микробиом</kwd><kwd>холангиты</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Министерство образования и науки РФ, Центр коллективного пользования «Регенеративная медицина» (ID310020)</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
