Поиск восприимчивых к широкому спектру вирусов клеточных культур является актуальной задачей.</p><sec><title>Цель работы</title><p>Цель работы: изучить чувствительность новых диплоидных клеточных культур животного происхождения (фибробласты почки и гортани плода свиньи) к вирусам Coxsackievirus B5 (CVB5) и Herpes simplex virus-1 (HSV-1).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: клеточные культуры фибробластов почки и гортани плода здоровой свиноматки получены методом щадящей трипсинизации. Чувствительность новых клеточных культур фибробластов почки и гортани плода свиньи (ФППС и ФГПС) к указанным вирусам определяли по степени цитопатического действия (ЦПД), выраженной в процентном соотношении. Изучение инфекционной активности вируса CVB5 проводили методом ПЦР в режиме реального времени с оценкой относительной величины порогового цикла амплификации (Ct); HSV-1 — количественным титрованием вируссодержащей жидкости (ВСЖ), значение показателя выражали в 50% тканевой цитопатической дозе (ТЦД50).</p></sec><sec><title>Результаты</title><p>Результаты: получены диплоидные клеточные культуры ФППС и ФГПС. Выявлены высокая чувствительность клеток ФППС к вирусу CVB5 с ЦПД 87,5±3,3% на 3 пассаже и удовлетворительная концентрация энтеровирусной РНК в ВСЖ, характеризующаяся значением порогового цикла на уровне 22–24 Ct. Чувствительность клеточной культуры ФППС к HSV-1 соответствовала 92,1±5,5% ЦПД, инфекционная активность — 104,25 ТЦД50/0,2 мл. У клеток ФГПС к изучаемым вирусам определены низкие показатели ЦПД и инфекционной активности.</p></sec><sec><title>Выводы</title><p>Выводы: новая диплоидная клеточная культура ФППС с подтвержденной чувствительностью к тестируемым вирусам (CVB5 штамма CB5-8100 и HSV-1 штамма HSV-1/L-2) с высоким уровнем ЦПД имеет перспективы использования в вирусологии и биотехнологии. Клеточная культура ФГПС может быть кандидатом для тестирования других представителей CVB5 и HSV-1.</p></sec></abstract><trans-abstract xml:lang="en"><p>The increase in the number of cell cultures for virology and biotechnology enhances the chances of a successful response to threats related to outbreaks of well-known and new human infectious diseases. It is a vital task to search for cell cultures sensitive to a wide spectrum of viruses.</p><p>The aim of the study was to investigate the sensitivity of new diploid animal cell cultures (fibroblasts of a foetal pig’s kidneys and larynx) to Coxsackievirus B5 (CVB5) and Herpes simplex virus-1 (HSV-1).</p><sec><title>Materials and methods</title><p>Materials and methods. The cultures of porcine foetal kidney fibroblasts (PFKF) and porcine foetal larynx fibroblasts (PFLF) were derived from a foetus of a healthy pig by mild trypsinisation. The study determined the sensitivity of these new PFKF and PFLF cultures to the above-mentioned viruses by the cytopathic effect (CPE) expressed as a percentage. The infectious activity of CVB5 was studied using real-time polymerase chain reaction (PCR) with the determination of amplification cycle threshold values (Ct); that of HSV-1 was studied using quantitative titration of the virus-containing liquid (VCL). Infectious activity values were expressed as tissue culture 50% infective doses (TCID50).</p></sec><sec><title>Results</title><p>Results. The authors developed diploid PFKF and PFLF cell cultures. PFKF cells demonstrated high sensitivity to CVB5, with a CPE of 87.5±3.3% after passage 3 and a satisfactory concentration of enterovirus RNA in the VCL of 22–24 Ct . The sensitivity of PFKF cells to HSV-1 corresponded to a CPE of 92.1±5.5%. In these cells, the infectious activity of HSV-1 corresponded to 104.25 TCID50/0.2 mL. The experiments with PFLF cells showed low CPE and infectious activity values for both viruses.</p></sec><sec><title>Conclusions</title><p>Conclusions. The study demonstrated high CPE values with the CVB5 (CB5-8100) and HSV-1 (HSV-1/L-2) strains as examples and confirmed the sensitivity of the new diploid PFKF cell culture to these test viruses. Thus, the PFKF cell culture offers potential applications in virology and biotechnology and may be a candidate for testing other strains of CVB5 and HSV-1.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диплоидная клеточная культура животного происхождения</kwd><kwd>фибробласты почки плода свиньи</kwd><kwd>фибробласты гортани плода свиньи</kwd><kwd>Coxsackievirus B5</kwd><kwd>Herpes simplex virus-1</kwd><kwd>CVB5</kwd><kwd>HSV-1</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diploid animal cell culture</kwd><kwd>porcine foetal kidney fibroblasts</kwd><kwd>porcine foetal larynx fibroblasts</kwd><kwd>Coxsackievirus B5</kwd><kwd>Herpes simplex virus-1</kwd><kwd>CVB5</kwd><kwd>HSV-1</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проводилось без спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study was conducted without sponsorship.</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">Ogilvie M.
