Гиперадренокортицизм, вызванный гормональным нарушением в результате длительного содержания в неволе и стресс-факторами и приведший к полиорганной недостаточности, ранее не наблюдался и не был описан у медведей. Повышенная секреция кортизола приводит не только к поражению внутренних органов, но и к сахарному диабету, снижению иммунной резистентности и, как следствие, к потере способности иммунной системы распознавать и уничтожать патогенные микроорганизмы. В литературных источниках встречаются сообщения о гибели животных, живущих в неволе, в результате бактериальных инфекций (например, генерализованный клостридиоз у гималайского медведя, легочной нокардиоз тихоокеанской афалины, грибковое поражение легких у северного оленя). Однако ни в одной из данных работ не проводили детального патологоанатомического и гистологического исследования всех органов. Представленный авторами клинический случай полиорганной недостаточности у бурого медведя в условиях зоопарка объединяет данные анамнеза, симптоматику, результаты лабораторных и инструментальных показателей при жизни животного, а также результаты патоморфологического, гистологического и гистохимического исследований. Эти данные позволяют рекомендовать зоопаркам минимизировать стресс-факторы у животных при их содержании, при необходимости прибегать к медикаментозной коррекции стресса, а также проводить ежеквартальную диспансеризацию для раннего выявления болезни и проведения своевременной и целенаправленной терапии. </p></abstract><trans-abstract xml:lang="en"><p>Brown bears are kept in various captive conditions, some of which can significantly deteriorate their health. Hyperadrenocorticism, caused by a hormonal disorder resulting from prolonged captivity and stress factors, and leading to multiple organ failure, has not been previously observed or described in bears. Increased cortisol secretion not only leads to damage of internal organs but also to diabetes mellitus, decreased immune resistance, and consequently, to the loss of the immune system’s ability to recognize and destroy pathogenic microorganisms. In literary sources, there are reports of deaths of animals living in captivity as a result of bacterial infections (for example, generalized clostridiosis in the Himalayan bear, pulmonary nocardiosis in the Pacific bottlenose dolphin, fungal lung disease in reindeer). However, none of these studies conducted detailed post-mortem and histological examinations of all organs. The clinical case of multiple organ failure in a brown bear in a zoo setting presented by us combines anamnestic data, symptomatology, results of laboratory and instrumental parameters during the animal’s life, as well as the results of pathomorphological, histological, and histochemical examinations. These data allow us to recommend that zoos minimize stress factors for animals in their care, resort to pharmacological correction of stress if necessary, and conduct quarterly health check-ups for early detection of disease and timely and targeted therapy. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>бурый медведь</kwd><kwd>зоопарк</kwd><kwd>полиорганная недостаточность</kwd><kwd>диагностика</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>brown bear</kwd><kwd>zoo</kwd><kwd>multiple organ failure</kwd><kwd>diagnosis</kwd><kwd>clinical case</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">Robbins C.T. et al.
