При этом долгосрочное культивирование существенно повышает риски заражения клеточного материала, в связи с чем возникает необходимость поддержания клеточной чистоты и удаления контаминантов в случае обнаружения заражения. В качестве контаминантов чаще всего выступают бактерии, дрожжи и грибы, в редких случаях вирусы и простейшие. Соответственно, для борьбы с биологическим заражением необходимо использовать препараты различной направленности в зависимости от природы контаминанта. В данной работе исследовано влияние наиболее распространённых в лабораторной практике препаратов антибиотической и антимикотической направленности на жизнедеятельность адгезивных перевиваемых клеточных культур человека. Показано, что разные клеточные культуры обладают различающейся чувствительностью к используемым для деконтаминации препаратам, что свидетельствует о необходимости разработки индивидуальных схем лечения для конкретной клеточной линии. Установлены безопасные диапазоны концентрации препаратов для клеток аденокарциномы лёгкого, остеосаркомы, колоректальной карциномы и эмбриональных клеток почки человека. С учётом полученных данных проведено лечение спонтанной контаминации в длительно культивируемом штамме линии H1299. Искусственное заражение исследуемых клеточных линий выявленным контаминантом с последующим лечением по аналогичной схеме подтвердило адекватность использования ципрофлоксацина для деконтаминации различных адгезивных культур в лабораторной практике.</p></abstract><trans-abstract xml:lang="en"><p>The absence of contamination is an important condition for the reliability of the results obtained when conducting experiments on cell cultures. At the same time, long-term cultivation significantly increases the risk of contamination of the cellular material, and therefore it is necessary to maintain cellular purity and remove contaminants in the event of contamination. The most common contaminants are bacteria, yeast and fungi, and, in rare cases, viruses and protozoa. Accordingly, to combat biological contamination, it is necessary to use drugs of different mechanisms depending on the nature of the contaminant. The article examines the effect of the most common antibiotic and antimycotic drugs in laboratory practice on the vital activity of continuous adherent human cell cultures. It was shown that different cell cultures have different sensitivity to the drugs used for decontamination, which indicates the need to develop individual treatment regimens for a specific cell line. Safe ranges of drug concentrations were established for lung adenocarcinoma, osteosarcoma, colorectal carcinoma, and human embryonic kidney cells. Taking into account the obtained data, spontaneous contamination was treated in a long-cultivated strain of the H1299 line. Artificial infection of the studied cell lines with the identified contaminant followed by treatment according to a similar scheme confirmed the adequacy of using ciprofloxacin for decontamination of various adherent cultures in laboratory practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>контаминация</kwd><kwd>ципрофлоксацин</kwd><kwd>H1299</kwd><kwd>U2OS</kwd><kwd>HEK293</kwd><kwd>HCT116</kwd><kwd>микоплазма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>contamination</kwd><kwd>ciprofloxacin</kwd><kwd>H1299</kwd><kwd>U2OS</kwd><kwd>HEK293</kwd><kwd>HCT116</kwd><kwd>mycoplasma</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (проект № 21-73-00296)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abatenh E., Gizaw B., Tsegaye Z.
