Оценивали возможность применения полимеразной цепной реакции с обратной транскрипцией в режиме реального времени для обнаружения вируса ящура в молоке крупного рогатого скота. Для приготовления образцов молока, инфицированных вирусом ящура, использовали штаммы А № 2177/Амурский/2013, О № 2123/Южная Осетия/2011, Азия-1 № 1987/Амурский/2005, С № 564, SAT-1 № 2033/Ботсвана, SAT-2/Саудовская Аравия, SAT-3/Bech 1/65. Для проверки специфичности ОТ-ПЦР-РВ использовали штаммы из коллекции штаммов микроорганизмов ФГБУ «ВНИИЗЖ»: вируса везикулярной болезни свиней – О-72, вируса везикулярной экзантемы свиней – А-48, вируса везикулярного стоматита – Индиана. Полученные данные показали, что ОТ-ПЦР в реальном времени может успешно применяться для обнаружения вируса ящура в молоке инфицированных коров так же, как в эпителиальных тканях и культурах клеток. Аналитическая чувствительность ОТ-ПЦР-РВ в образцах молока составляет 1–10 ТЦД50/мл, специфичность метода – 100%. При определении основных валидационных характеристик метода доказано, что ОТ-ПЦР-РВ обладает высокой прецизионностью, специфичностью и чувствительностью и способна обнаруживать вирус ящура во всем его генетическом разноообразии. Таким образом, полученные данные показали, что ОТ-ПЦР-РВ является ценным методом для контроля молока и молочной продукции.</p></abstract><trans-abstract xml:lang="en"><p>FMDV can be shed with milk of infected animals and infect susceptible animals. The possibility of using real-time qRT-PCR for FMD virus detection in cattle milk was assessed. To prepare samples of FMDV infected milk the following strains were used: А No. 2177/ Amursky/2013, О No. 2123/South Ossetia/2011, Asia-1 No. 1987/Amursky/2005, С No. 564, SAT-1 No. 2033/Botswana, SAT-2/Saudi Arabia, SAT-3/Bech 1/65. For specifcity test swine vesicular disease O-72 strain, Vesicular Exanthema of Swine A-48 strain and vesicular stomatitis virus Indiana strain from FGBI “ARRIAH” collection were used. The obtained data showed that real time qRT-PCR can be successfully used for the virus detection in milk of infected cows as well as in epithelium and cell cultures. Analytical sensitivity of real-time qRT-PCR in milk samples is 1–10 TCD50/ml, the method specifcity is 100%. When identifying basic validation characteristics of the method it was proven that real-time qRT-PCR demonstrates precision and sensitivity and can detect FMDV in its genetic diversity. So, the detected data showed that the real-time qRT-PCR is a precious method of milk and dairy product control.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус ящура</kwd><kwd>молоко</kwd><kwd>ОТ-ПЦР в реальном времени</kwd><kwd>валидация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>FMD virus</kwd><kwd>milk</kwd><kwd>real-time qRT-PCR</kwd><kwd>validation</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">Поляков И.
