Животные: овцы породы «Южная мясная» возрастом от 8 до 12 мес. Паразитические нематоды сем. Trichostrongylidae были получены из сычугов овец. Самцов и самок нематод сохраняли в отдельных промаркированных пробирках типа «Эппендорф» при -20 оС. Молекулярно-генетические исследования. Выделение нативной геномной ДНК проводили с использованием коммерческого набора для экстракции ДНК из микроколичеств тканей "ДНК-Экстран-2" («Синтол», Москва). Проведение «вложенной ПЦР». Для амплификации ДНК использовали термоциклер T-100 Bio-Rad и коммерческий набор реактивов Master Mix, Евроген.  Полученные фрагменты ДНК использовали в качестве основного компонента для проведения реакции рестрикции с эндонуклеазой RsaI («Сибэнзим», г. Новосибирск). Выявление резистентного генотипа T. circumcincta методом ПЦР. Мультиплексную ПЦР проводили в соответствии с рекомендациями Silvestre et al, 2000 с использованием коммерческого набора реактивов Master Mix, Евроген. Результаты электрофореза анализировали в гель-документирующей системе GelDoc, Bio-Rad. Секвенирование полученных фрагментов проводили в компании ЦКП «Геном» ФГБНУ «МГНЦ» (Москва).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение.

Animals: The Southern sheep aged 8 to 12 months. Parasitic nematodes of the family Trichostrongylidae were isolated from sheep abomasums. Male and female nematodes were preserved in separate labeled Eppendorf tubes at -20 оС. Molecular genetic testing. Native genomic DNA was isolated using a commercial kit DNA-Extran-2 (Synthol, Moscow) for DNA extraction from microgram quantities of tissues. Nested PCR. For DNA amplification, a T-100 BioRad thermal cycler and a commercial Master Mix reagent kit, Evrogen, were used.  The resulting DNA fragments were used as the main component for a restriction reaction with RsaI endonuclease (SibEnzyme, Novosibirsk). PCR-based detecting the resistant genotype of T. circumcincta. Multiplex-PCR was performed as recommended by Silvestre et al., 2000, using a commercial Master Mix reagent kit, Evrogen. The electrophoresis results were analyzed in the GelDoc gel-documenting system, Bio-Rad.

To identify β-tubulin gene mutations that lead to benzimidazole anthelmintic resistance in parasitic nematodes of the species T. circumcincta, molecular genetic testing was conducted using nested PCR, restriction fragment length polymorphism analysis, and multiplex-PCR methods.
