По количеству выявленных случаев он значительно уступает сальмонеллезам и кампилобактериозам, но превосходит их по тяжести клинического течения и проценту летальных исходов. Поэтому разработка видоспецифичных методов ПЦР для выявления генома L.monocytogenes является актуальной задачей. Оптимизирована методика выявления генома бактерий L. monocytogenes посредством полимеразной цепной реакции в режиме реального времени (ПЦР-РВ). Мишенью амплификации являлся высокоспецифичный и подходящий для точной качественной оценки всех штаммов ген iap, кодирующий поверхностный белок р60 L.monocytogenes. Подобрана оптимальная концентрация магния (6 мМ) и температура отжига праймеров (57 °С). Определены чувствительность и специфичность данной методики. Предел обнаружения составил 120 молекул-мишеней. Полученные результаты показывают, что оптимизированный вариант ПЦР-РВ, основанный на амплификации гена iap, позволяет выявлять L.monocytogenes в пробах продовольственного сырья животного происхождения и пищевых продуктов. Скрининговые исследования на основе оптимизированной ПЦР-РВ обеспечивают быстрые и надежные результаты.</p></abstract><trans-abstract xml:lang="en"><p>Listeria monocytogenes is one of the major food contaminants causing the illness, called Listeriosis. Listeriosis incidence is much less, than the number salmonellosis and campylobacteriosis cases, but the clinical disease is significantly more severe and has a higher mortality. That’s why the development of species-specific PCR techniques to detect L. monocytogenes genome is a topical task. L. monocytogenes bacteria genome detection technique using real-time polymerase chain reaction (qRT-PCR) was improved. The amplification target was a highly specific and suitable for qualification of all strains iap gen, coding L. monocytogenes р60 surface protein. Optimum magnesium concentration (6 mM) and primer annealing temperature (57 °С) were selected. The sensitivity and specificity of the technique were identified. Detection threshold was 120 target molecules. The results obtained demonstrate that optimized qRT-PCR version, based on iap gen amplification, enables to detect L. monocytogenes in animal product and food samples. Optimized qRT-PCR-based screening tests ensure rapid and reliable results.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ПЦР-РВ</kwd><kwd>Listeria monocytogenes</kwd><kwd>пищевые продукты животного происхождения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>qRT-PCR</kwd><kwd>Listeria monocytogenes</kwd><kwd>food products of animal origin</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">Бхуниа А.
