Показатель качества «Количество живых микробных клеток» определяется на всех этапах производства вакцины чумной живой. В настоящее время для определения количества живых микробных клеток используют бактериологический метод. Однако для повышения точности анализа и сокращения времени его проведения перспективным представляется использование метода проточной цитометрии.</p></sec><sec><title>Цель</title><p>Цель. Изучить возможность применения метода проточной цитометрии в оценке качества препарата вакцины чумной живой.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Использовали экспериментальные серии вакцины чумной живой (пять серий). Изучение показателя качества «Количество живых микробных клеток» в препарате вакцины проводили бактериологическим методом согласно требованиям Государственной фармакопеи Российской Федерации (ФС.3.3.1.0022.15). Цитофлуориметрический анализ образцов проводили с использованием флуоресцентного красителя SynaptoGreen.</p></sec><sec><title>Результаты</title><p>Результаты. Проведена оценка значения количества живых микробных клеток в образцах вакцин бактериологическим методом, что составило от 27,8±2,2 до 56,5±3,1% (в среднем — 39,8±5,4%), и методом проточной цитометрии — от 29,2±1,2 до 59,1±2,1%, (в среднем — 41,7±5,5%). Статистическая обработка данных показала, что результаты контроля качества препарата вакцины, полученные обоими методами, не имели достоверных различий и характеризовались высоким коэффициентом детерминации.</p></sec><sec><title>Выводы</title><p>Выводы. Показана целесообразность применения метода проточной цитометрии при контроле качества препарата чумной вакцины при определении количества живых микробных клеток. Высокая информативность, быстрота и простота выполнения анализа делают метод проточной цитометрии более предпочтительным в сравнении с традиционными методами анализа.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Scientific relevance</title><p>Scientific relevance. The number of live bacteria is a quality parameter controlled at all stages of live plague vaccine production. Currently, live microbial cell counting uses a bacteriological method. However, flow cytometry has the potential to increase analytical accuracy and reduce testing time.</p></sec><sec><title>Aim</title><p>Aim. This study aimed at testing the applicability of flow cytometry to assessing the quality of live plague vaccines.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study quantified live microbial cells in 5 experimental batches of live plague vaccine as part of their quality control using the bacteriological method according to the State Pharmacopoeia of the Russian Federation (FS.3.3.1.0022.15). Cytofluorometry of the samples used the SynaptoGreen fluorescent dye.</p></sec><sec><title>Results</title><p>Results. The study quantified live microbial cells in live plague vaccine samples using the bacteriological method and flow cytometry. The results obtained by the bacteriological method ranged from 27.8±2.2 to 56.5±3.1% with an average of 39.8±5.4%. The results obtained by flow cytometry ranged from 29.2±1.2 to 59.1±2.1% with an average of 41.7±5.5%. The statistical analysis showed no significant difference between the results of vaccine quality control by both methods, as well as a high coefficient of determination.</p></sec><sec><title>Conclusions</title><p>Conclusions. The results show that flow cytometry is an appropriate method for the quantification of live microbial cells as part of the quality control of plague vaccines. Being quick, easy, and highly informative, flow cytometry is preferable to traditional methods.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>метод проточной цитометрии</kwd><kwd>вакцина чумная живая</kwd><kwd>контроль качества</kwd><kwd>количество живых микробных клеток</kwd><kwd>бактериологический метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flow cytometry</kwd><kwd>live plague vaccine</kwd><kwd>quality control</kwd><kwd>number of live bacteria</kwd><kwd>percentage of live microbial cells</kwd><kwd>bacteriological method</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">Касина ИВ, Ращепкин ЛИ, Горяев АА, Алексеева СА, Немировская ТИ, Мовсесянц АА.
