Исследовано влияние хронического иммобилизационного стресса на микробиоту толстой кишки экспериментальных животных. Для оценки качественного и количественного состава микробиоценоза данного биотопа использовали биоптаты слизистой оболочки толстой кишки крыс линии Вистар. Установлено, что воздействие стресса приводило к значительному снижению количества облигатных представителей микробиоты, при этом возрастало содержание факультативной микрофлоры. Оценка частоты встречаемости и относительного среднего идентифицированных родов микроорганизмов показала, что хроническая иммобилизация значительно изменяла значения исследованных показателей в отношении условно-патогенных представителей микробиоценоза, а также влияла на их соотношение с облигатными бактериями. Полученные данные наглядно демонстрируют роль стресса в формировании дисбиоза.</p></abstract><trans-abstract xml:lang="en"><p>Stress as an actual medical and biological factor necessitates the study of its various consequences for the macroorganism. The article deals with chronic restraint stress effects on the experimental animals’ colon microbiota. To assess the qualitative and quantitative composition of the microbiocenosis of this biotope, biopsy specimens of the mucous membrane of the large intestine of Wistar rats were used. It was established that stress led to a significant decrease in the number of obligate representatives of the microbiota, while the content of the facultative microflora increased. Evaluation of the frequency of occurrence and the relative average of the identified genera of microorganisms showed that chronic immobilization significantly changed the values of the studied parameters in relation to opportunistic pathogenic representatives of the microbiocenosis, and also affected their correlation with obligate bacteria. The obtained data clearly demonstrate the role of stress in the dysbiosis creation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая иммобилизация</kwd><kwd>стресс</kwd><kwd>микробиота</kwd><kwd>микрофлора</kwd><kwd>дисбиоз</kwd><kwd>ось «микробиота - кишечник - мозг»</kwd></kwd-group><kwd-group xml:lang="en"><kwd>restraint stress</kwd><kwd>immobilization</kwd><kwd>microbiota</kwd><kwd>microflora</kwd><kwd>dysbiosis</kwd><kwd>microbiota-gut-brain axis</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">Богданова, Е.
