Материалы и методы. Для достижения указанной цели в работе представлен набор реагентов ПЦР -тест-системы «Гены V. cholerae О1 вариант ctxB-rtxC, FL», а также способ осуществления идентификации V. cholerae O1 с дифференциацией на типичные токсигенные и генетически измененные варианты. Изучены специфичность, специфическая активность и чувствительность разработанной тест-системы на 35 штаммах V. cholerae O1, 6 штаммах V. cholerae non O1, 5 гетерологичных штаммах (Shigella zonnei – 2 штамма, по одному штамму Salmonella typhimurium, S. enteritidis, Escherichia coli). Результаты и обсуждение. Набор реагентов ПЦР -тест-системы «Гены V. cholerae вариант ctxB-rtxC, FL» выявляет в геноме токсигенных V. cholerae О1 фрагменты ДНК генов ctxBСl, ctxBEl, rtxC (обладает специфической активностью, аналитическая чувствительность 1∙103 ГЭ /мл) и не обнаруживает данные гены у нетоксигенных V. cholerae О1 и non O1, а также у гетерологичных штаммов микроорганизмов (показана специфичность 100 %). На ПЦР -тест-систему «Гены V. cholerae вариант ctxB-rtxC, FL» получен патент РФ № 2732448, опубл. 24.08.2020, бюл. № 24. ПЦР -тест-система «Гены Vibrio cholerae О1 вариант ctxB-rtxC, FL» может быть использована для повышения эффективности системы эпидемиологического надзора за холерой и проведения обоснованного объема противоэпидемических мероприятий в случае ее завоза на территорию Российской Федерации.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the work was to analyze and assess the results of using PCR test-system “V. cholerae variant ctxB-rtxC FL genes” for identification of Vibrio cholerae O1 with differentiation between typical toxigenic and genetically modified variants in a multiplex format with a real-time hybridization-fluorescent recording of results. Materials and methods. To achieve this goal, a set of reagents for the PCR test-system “V. cholerae O1 variant ctxB-rtxC FL genes”, as well as a method for identifying V. cholerae O1 with differentiation between typical toxigenic and genetically altered variants were utilized. The specificity, specific activity and sensitivity of the developed test-system by the example of 35 V. cholerae O1 strains, 6 V. cholerae non-O1 strains, 5 heterologous strains (Shigella zonnei – 2 strains, one Salmonella typhimurium strain, S. enteritidis, Escherichia coli) were investigated. Results and discussion. The panel of reagents for the PCR test system “V. cholerae variant ctxB-rtxC FL genes” detects DNA fragments of the ctxBCl, ctxBEl, rtxC genes in the genome of toxigenic V. cholerae О1 (has specific activity, analytical sensitivity 1·103 GE/ml) and does not detect these genes in non-toxigenic V. cholerae O1 and non-O1, as well as in heterologous strains of microorganisms (100 % specificity). RF Patent No. 2732448 was granted for the PCR test-system “V. cholerae variant ctxB-rtxC FL genes”. It can be used to increase the efficiency of the epidemiological surveillance system and to carry out a justified scope of anti-epidemic measures in the event of cholera importation into the territory of the Russian Federation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>типичные токсигенные и генетически измененные варианты холерного вибриона биовара Эль Тор</kwd><kwd>ПЦР -тест-система для идентификации возбудителя холеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>typical toxigenic and genetically modified variants of Vibrio cholerae biovar El Tor</kwd><kwd>PCR test-system for identification of the causative agent of cholera</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">De Haan L., Hirst T.R.
