При BLAST-анализе хромосомной ДНК B. anthracis в качестве мишеней определены два гена профага lambdaBa03: BA_5358 (AE016879.1: 4852332..4853642) и BA_5361 (AE016879.1: 4855298..4856278). Разработанные праймеры и флуоресцентные гидролизуемые пробы TaqMan для одновременной детекции хромосомной ДНК B. anthracis по двум указанным генам проверены в реакциях ПЦР в реальном времени на чувствительность и специфичность.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение.

Чувствительность разработанного мультиплексного набора, исследованная на образцах ДНК вакцинного штамма м55‑ВНИИВВиМ и архивных образцах ДНК B. anthracis, составила 100 фг бактериальной ДНК, что в пересчете определяет предел чувствительности в 16,72 бактериального генома на реакцию.

Studies performed on chromosomal DNA samples of closely related bacteria (B. cereus, B. thuringiensis, B. subtilis, B. clausii) have shown 100 % specificity of the developed sets of primers/probes. The sensitivity of the devised multiplex kit, tested on DNA samples of the m55-VNIIVViM vaccine strain and archival DNA samples of B. anthracis, reached 100 fg of bacterial DNA, which sets the limit of sensitivity at 17 genomes per reaction. The developed multiplex kit can be used as a separate tool for research laboratories studying anthrax.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Bacillus anthracis</kwd><kwd>ПЦР в реальном времени</kwd><kwd>lambdaBA_5358</kwd><kwd>lambdaBA_5361</kwd><kwd>сибирская язва</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Bacillus anthracis</kwd><kwd>real-time PCR</kwd><kwd>lambdaBA_5358</kwd><kwd>lambdaBA_5361</kwd><kwd>anthrax</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Финансирование.
