Иркутская область относится к территориям России, неблагополучным по туберкулезу. Ситуация в области усугубляется существованием активных туристических и торгово-транспортных контактов с Монголией, которая является страной с более высоким бременем ТБ. Цель. Оценить возможность использования клинического материала от больных ТБ для реализации оперативного мониторинга в системе эпидемиологического анализа трансграничного распространения туберкулеза.Материалы и методы. Исследован 161 образец мокроты и операционного материала от впервые выявленных больных ТБ с положительным результатом молекулярно-генетического теста в системе GeneXpert MTB/RIF. Методом ПЦР с детекцией в реальном времени (ПЦР-РВ) с праймерами и зондами собственного дизайна была проведена идентификация эпидемических субтипов генотипа Beijing (субтипы В0/W148, Central Asian, Asian-African 2. Результаты и обсуждение. Использование мокроты и операционного материала с положительными результатами молекулярно-генетического теста и микроскопии в качестве диагностического образца позволяет обнаружить различия между эпидемическими субтипами генотипа Beijing в 92,9% случаев. Частота выявления российских эпидемических субтипов Central Asian (45,1%) и В0/W148 (20,3%) в клинических образцах значимо не отличается от данных по штаммам M. tuberculosis в Иркутской области. «Монгольский» субтип Asian-African 2 генотипа Beijing в исследуемой когорте не идентифицирован ни одном случае. Выводы. Полученные результаты свидетельствуют о применимости использованных тестов на клинических образцах как инструмента для экспресс-мониторинга в комплексе эпидемиологического надзора трансграничной передачи туберкулеза.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. The Irkutsk region belongs to the territories of Russia unfavorable for tuberculosis. The situation in the region is exacerbated by the existence of active tourism and trade and transport contacts with Mongolia, which is a country with a higher burden of TB.Aims. To assess the applicability of using subtype-specific PCR tests on clinical samples of TB patients to crossborder transmission analysis of the M. tuberculosis. Materials and methods. we investigated the cohort of 161 sputum and surgical specimens from newly diagnosed TB patients with a positive molecular genetic test (GeneXpert). The epidemic subtypes of the Beijing genotype (subtypes B0/W148, Central Asian, Asian-African 2) were identified by the method PCR with real-time detection (RT-PCR) with primers and probes of our own design. Results. The use of respiratory and surgical specimens with positive results of a molecular genetic test and microscopy makes it possible to differentiate epidemic subtypes of the Beijing genotype in 92.9% of cases. The frequency of detection of the Russian epidemic subtypes Central Asian (45.1%) and B0/W148 (20.3%) in clinical samples does not differ from data strains from the Irkutsk region. The «Mongolian» subtype Asian-African 2 of the Beijing genotype was not identified in the clinical samples in any case. Conclusions. The results indicate the applicability of the used tests for rapid monitoring as a stage in the complex of transboundary surveillance of tuberculosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эпидемиологический надзор за туберкулезом</kwd><kwd>эпидемические субтипы</kwd><kwd>M. tuberculosis</kwd><kwd>клинический образец</kwd><kwd>трансграничный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>TB surveillance</kwd><kwd>epidemic strains</kwd><kwd>M. tuberculosis</kwd><kwd>clinical sample</kwd><kwd>cross-border transmission analysis</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">Pérez-Lago L., Martínez Lirola M., Herranz M., et al.
