В работе представлены результаты хранения семи штаммов V. cholerae в течение трех лет в пяти защитных средах, содержащих в качестве криопротектора глицерин или лактозу (10, 20, 30 % водные растворы глицерина, мясопептонный бульон с 10 % глицерина, среда с 15 % лактозы и 3 % желатина). Показано, что гибель холерных вибрионов происходит при замораживании-размораживании образцов и их хранении. После трех лет консервации количество живых клеток уменьшилось во всех средах, но в разной степени. Наиболее высокая выживаемость холерных вибрионов после замораживания-размораживания и хранения в замороженном состоянии по используемому протоколу отмечена в лактозо-желатиновой среде. При использовании в качестве протективной среды водного раствора глицерина оптимальной является концентрация криопротектора 20 %. После трех лет хранения при -70 °С все штаммы, независимо от состава защитной среды, сохранили основные диагностически значимые фенотипические признаки. Таким образом, холерные вибрионы могут быть сохранены без пересевов в течение трех лет (срок наблюдения) без изменения основных диагностических признаков во всех тестируемых защитных средах при -70 °С.</p></abstract><trans-abstract xml:lang="en"><p>Objective of the study is to evaluate cholera vibrio resistance to freezing and freeze preservation at -70 °C in the presence of cryoprotectors. The study outlines the results of storage of seven different V. cholerae strains within three-years term in the protective media containing glycerin or lactose (10, 20, 30 % aquatic solutions of glycerin, meat-peptone broth with 10 % of glycerin, a medium with 15 % of lactose and 3 % of gelatin) as cryoprotectors. Demonstrated is the fact that cholera vibrio death occurs during freezing-refreezing procedure and preservation of samples. After three-year conservation the numbers of living cells decrease in all types of media, but to different extent. The highest survival rate in cholera vibrios after freezing-refreezing procedure and freeze preservation in accordance with applicable protocols is observed in lactose-gelatin medium. When using aquatic solution of glycerin as protective medium, optimum turns out to be the cryoprotector concentration equal to 20 %. After three-year preservation at -70 °C all the strains, irrespective of the protective medium composition, retain their basic diagnostically significant phenotypic characteristics. Thus, cholera vibrios can be conserved free from subcultures within three-year term (period of observation) without alterations to their basic diagnostic properties in all tested protective media but at -70 °C.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>холерные вибрионы</kwd><kwd>замораживание</kwd><kwd>низкотемпературная консервация</kwd><kwd>криопротекторы</kwd><kwd>жизнеспособность</kwd><kwd>cholera vibrios</kwd><kwd>freezing</kwd><kwd>low-temperature conservation</kwd><kwd>cryoprotectors</kwd><kwd>survivability</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">Лабораторная диагностика холеры: Методические указания.
