Оптимизировать параметры тестирования антимикробной активности модифицированных нетканых материалов, используемых для изготовления медицинских масок, в отношении изолятов микроорганизмов с выраженными фенотипическими признаками агрессии и провести количественную оценку антимикробного потенциала методом с импедиметрической детекцией.Материалы и методы. Оценку антимикробного потенциала проводили, моделируя прямой контакт материала после обработки растворами октенидина гидрохлорида, в условиях in vitro методом с импедиметрической детекцией на основании предложенного маркера IDT — продолжительности lag-фазы развития популяции тест-штамма с использованием программного обеспечения микробиологического анализатора. Антимикробный потенциал рассчитывали по предложенной формуле и оценивали в соответствии с обоснованной количественной шкалой.Результаты. В лабораторных условиях оптимизированы параметры тестирования антимикробной активности нетканых материалов с антимикробной обработкой октенидина гидрохлоридом с использованием инструментального метода с импедиметрической детекцией. Установлено, что изолят Escherichia coli 43-02012021 и изолят Enterobacter cloaceae 14-21072021 были более чувствительны к воздействию образца, полученного методом электронно-лучевого напыления октенидина гидрохлорида из активной газовой фазы, по сравнению с образцом, полученным методом импрегнирования октенидина гидрохлоридом wet chemistry из раствора в вакууме.Заключение. Метод оценки с импедиметрическим принципом детекции расширяет арсенал инструментальных методов количественного определения антимикробного потенциала нетканых материалов. Стандартные отклонения измерений σ составили 4,4–8,1 %, что является приемлемым для получения достоверных результатов в условиях внутрилабораторного тестирования.</p></abstract><trans-abstract xml:lang="en"><p>Objective. To optimize the parameters for testing the antimicrobial activity of modified non-woven materials used for the manufacture of medical masks against microorganism isolates with strong phenotypic aggression signs, and to quantify their antimicrobial potential using a method with impedimetric detection.Materials and methods. The antimicrobial potential was assessed by simulating a direct contact of the material after treatment with octenidine dihydrochloride solutions under in vitro conditions by the method with impedimetric detection based on the proposed IDT marker – duration of the lag-phase of the growth of a test stain population using the software of a microbiological analisator. The antimicrobial potential was calculated according to the proposed formula and evaluated in accordance with a reasonable quantitative scale.Results. The parameters for testing the antimicrobial activity of nonwoven materials with antimicrobial octenidine dihydrochloride treatment using an instrumental method with impedimetric detection have been optimized in laboratory conditions. It was found that Escherichia coli 43-02012021 isolate, Enterobacter cloaceae 14-21072021 isolate were more sensitive to the impact of the sample obtained by the method of electron beam deposition of octenidine hydrochloride from the active gas phase compared with the sample obtained by wet impregnation from octenidine hydrochloride solution in vacuum.Conclusion. The evaluation method with the impedimetric detection principle expands the arsenal of instrumental methods of quantitative determination of the antimicrobial potential of nonwoven materials. The standard deviations of σ measurements were 4.4-8.1 %, which is acceptable for obtaining reliable results under the conditions of intralaboratory testing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>маски медицинские</kwd><kwd>тест-штаммы</kwd><kwd>тестирование</kwd><kwd>антимикробный потенциал</kwd><kwd>маркеры</kwd><kwd>критериальная шкала</kwd><kwd>импедиметрические параметры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>medical masks</kwd><kwd>test strains</kwd><kwd>testing</kwd><kwd>antimicrobial potential</kwd><kwd>markers</kwd><kwd>criteria scale</kwd><kwd>impedimetric parameters</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">Munteanu F-D, Titoiu AM, Marty J-L, Vasilescu A.
