Для проведения эффективной диагностики требуется гармонизация методов с международными и региональными диагностическими протоколами, следует также учитывать необходимость импортозамещения рекомендуемых реагентов. В ходе исследований, проведенных на базе ФГБУ ВНИИКР были оптимизированы 5 ПЦР-тестов с компонентами отечественного производства и определены их основные критерии эффективности согласно стандарту ЕОКЗР 7/098 (4). Дополнительно проведена валидация коммерческого набора «Фитоскрин» (ООО «Синтол», Россия). Результаты оценки применимости показали высокую чувствительность ПЦР-РВ в соответствии с Harper et al. (2010), Li et al. (2013), и Ouyang et al. (2013), которая составила 102 КОЕ/мл, высокую специфичность (не было обнаружено ложноположительных или неспецифичных реакций), а также 100 %-ную в опыте прецизионность в условиях повторяемости и промежуточную прецизионность. Данные тесты войдут в методические рекомендации по диагностике X. fastidiosa как отборочные. Также следует отметить повышение чувствительности ПЦР по Li et al. (2013), с реакционной смесью 5х MasCFЕ TaqMIX -2025 («Диалат Ltd.», Россия) по сравнению с данными, представленными в отчете TPS (2018). Кроме того, установлено, что ПЦР-РВ по Francis et al. (2006) и классическая ПЦР по Minsavage et al. (1994) имеют аналитическую чувствительность 100 % при концентрации целевого объекта 103 КОЕ/мл и 104 КОЕ/мл соответственно. Выявлена селективность всех ПЦР-РВ, кроме коммерческого набора «Фитоскрин» по отношению к экстракту лаванды, который характеризовался ингибированием амплификации.</p></abstract><trans-abstract xml:lang="en"><p>The grape bacteriosis agent (Pierce disease), namely, Xylella fastidiosa, represents a quarantine disease that is absent on the territory of the Eurasian Economic Union. For its efficient detection, the methods should be harmonised with international and local protocols; the import substitution of the recommended reagents should be considered. Five PCR tests were optimised using domestically produced compounds, and their main efficiency criteria, as per the EPPO standard 7/098 (4), were determined during studies carried out at the FSBI VNIIKR. In addition, a commercial kit, “Phytoscreen” (LLC “Syntol”, Russia), was validated. The results of the applicability assessment revealed a high sensitivity of real-time PCR (102 CFU/ml) following Harper et al. (2010), Li et al. (2013) and Ouyang et al. (2013), high sensitivity (no false positive or non-specific reactions were detected) and 100 % precision in experiment and site precision. These tests will be included in the guidelines for detecting X. fastidiosa as a screening test. It should be noted that the sensitivity of PCR, as per Li et al. (2013), using the 5x MasCFE TaqMIX -2025 reaction mixture (“Dialat Ltd.”, Russia), was improved relative to the data reported in TPS (2018). In addition, real-time PCR based on Francis et al. (2006) and classical PCR, as per Minsavage et al. (1994), exhibit an analytical sensitivity of 100 % at target concentrations of 103 and 104 CFU/ml, respectively. All real-time PCR showed selectivity for lavender extract, excluding the commercial Phytoscreen kit, which was characterised by inhibition of amplification.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Пирса</kwd><kwd>Xylella fastidiosa</kwd><kwd>ПЦР</kwd><kwd>ДНК</kwd><kwd>оценка применимости</kwd><kwd>критерии эффективности</kwd><kwd>диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pierce disease</kwd><kwd>Xylella fastidiosa</kwd><kwd>PCR</kwd><kwd>DNA</kwd><kwd>applicability assessment</kwd><kwd>efficiency criteria</kwd><kwd>detection</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">EPPO Global Database: Xylella fastidiosa, 2021 URL: https://gd.eppo.int/taxon/XYLEFA.
