Изучение роли кадаверина в адаптации холерных вибрионов к стрессу, обусловленному гипоксией. Материалы и методы. В работе использовано 18 штаммов V.cholerae с различным набором детерминант патогенности, выделенные от больных и из речной воды. Результаты и выводы. Показано, что при экспериментальном моделировании газовой среды кишечника, холерные вибрионы реагируют на неблагоприятные условия окружающей среды путем продукции кадаверина. При этом его количество коррелирует с патогенностью культур (оно выше у эпидемически значимых штаммов, чем у штаммов, лишенных генов токсино-и пилепродукции). Установлено, что уровень продукции внеклеточного кадаверина выше, чем внутриклеточного, но соотношение этих показателей зависит от концентрации кислорода и углекислоты в окружающей среде. Внутриклеточный кадаверин образуется, в основном, при условии высокой концентрации кислорода (10-12 %), при выраженной гипоксии (&lt;1 % О2) и повышении уровня углекислого газа (9-13 %) его количество резко снижается.</p></abstract><trans-abstract xml:lang="en"><p>Objective of the study is to evaluate the role of cadaverine in cholera vibrio adaptation to stress, induced by hypoxia. Materials and methods. Utilized have been 18 V. cholerae strains with different set of pathogenicity determinants. The strains are isolated from patients and from river-water. Results and conclusions. It is demonstrated that under experimental modeling of intestinal tract gas medium, cholera vibrios respond to unfavorable conditions of the environment by producing cadaverine. Its amount coincides with pathogenicity of cultures (it is higher in epidemically significant strains, than in the strains that lack genes of toxin and pilus production). It is established that the level of extracellular cadaverine production is greater than that of intracellular; but correlation of the parameters depends upon the oxygen and carbon dioxide concentration in the environment. Intracellular cadaverine is mainly generated at a high oxygen concentration (10-12 %); while under extreme hypoxia (&lt;1 % O2) and in case of carbon dioxide level increase (9-13 %), its production markedly declines.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ПЦР-анализ</kwd><kwd>Yersinia pestis</kwd><kwd>учебные штаммы</kwd><kwd>биологическая безопасность</kwd><kwd>PCR-analysis</kwd><kwd>strains used for educational purposes</kwd><kwd>biological safety</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">Бутурова Л.И.
