Обнаружено 12 штаммов, формирующих типичные прозрачные и атипичные мутные колонии. Среди последних выявлено 3 штамма, вариабельность морфологии которых коррелировала с изменением продукции экзополисахарида, холерного токсина, гемолизина, растворимой гемагглютинин/протеазы и подвижности. Одним из внешних сигналов, вызывающих координированное переключение продукции указанных факторов патогенности и персистенции является щелочная (рН 9,0) реакция среды. Возможно, переключение «прозрачные-мутные» варианты относится к одной из форм фазовых вариаций и необходимо V. cholerae для выживания в изменяющихся условиях внешней среды.</p></abstract><trans-abstract xml:lang="en"><p>Analysis of the population structure of 41 Vibrio cholerae biovar eltor natural strains permitted to detect 12 strains forming typical transparent and atypical opaque colonies. Among the later were identified 3 strains which morphology variability correlated with altered production of exopolysaccharide, cholera toxin, hemolysine, soluble hemagglutinin/protease and altered mobility. One of the external signals causing coordinating switching of production of the indicated pathogenicity and persistence factors is alkaline (pH 9,0) reaction of the medium.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Vibrio cholerae</kwd><kwd>гетерогенная популяция</kwd><kwd>координированное переключение экспрессии генов вирулентности и персистентности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Vibrio cholerae</kwd><kwd>heterogeneous population</kwd><kwd>coordinated change of virulence and persistence gene expression</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">Адамов А.К., Наумшина М.С.
