To characterize pool of Crohn’s disease-associated E.coli isolated from patients with Crohn’s disease. Materials and methods. 28 clinical stains were selected. Clinical isolates, as well as control samples, were tested for their possible belonging to a certain phylogenetic group, the ability to adhere and invade on the model of a monolayer of CaCo2 epithelial cells, the ability to form biofilms and their mobility. Results. We have shown that E.coli, isolated from a different biomaterial, belonged to different phylogenetic groups and differed in their ability to form biofilms. Adhesive-invasive E.coli were found mainly in the material of biopsy of the intestinal mucosa of patients with Crohn’s disease. Conclusion. There are reasons to suppose that adhesive-invasive E.coli formed at the junction of ecological niches of the lumen and the intestinal wall.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Оценить пул E.coli внутри пораженной зоны кишечника пациентов с болезнью Крона. Материалы и методы. Клинические изоляты (28), а также контрольные образцы были протестированы относительно их возможной принадлежности к определенной филогенетической группе, способности к адгезии и инвазии на модели монослоя эпителиальных клеток СаСо2, способности к формированию биопленки и подвижности. Результаты. Было показано, что E.coli, высеянные из различного биоматериала, отличались по филогенетической принадлежности и способности образовывать биопленку. E.coli, относящиеся к типу адгезивно-инвазивных, обнаруживались преимущественно в материале биопсии слизистой кишечника пациентов с болезнью Крона. Заключение. Есть основания полагать, что тип адгезивно-инвазивных E.coli сложился на стыке экологических ниш просвета и стенки кишечника.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Crohn’s disease</kwd><kwd>adhesive-invasive E.coli</kwd><kwd>heterological models</kwd><kwd>biofilms</kwd><kwd>phylogenetic diversity of E.coli</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>болезнь Крона</kwd><kwd>адгезивно-инвазивные E.coli</kwd><kwd>гетерологические модели</kwd><kwd>биопленки</kwd><kwd>филогенетическое разнообразие E.coli</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ahmed I., Roy В.
