Определить распространенность маркеров парентерального вирусного гепатита В у доноров крови и ее компонентов в Республике Беларусь.   Материал и методы. В исследование был включен 61 образец сывороток/плазмы крови, собранных от доноров из всех регионов страны. Все образцы были исследованы методами ХЛИА/ИФА и ПЦР на наличие маркеров вируса гепатита В.   Результаты. Как показали проведенные исследования, из 61 секвенированного образца 58 (95,1 %) относились к генотипу D, 3 (4,9 %) — к А. Генотип D в 47 (81,1 %) случаях был представлен подгенотипом D2, в 5 (8,6 %) образцах был выявлен подгенотип D1, в 5 (8,6 %) — D3, в 1 (1,7 %) пробе выявили подгенотип D4; все образцы генотипа А относились к подгенотипу А2. Все последовательности ДНК подгенотипов D1 и D3 были отнесены к подтипу ayw2, D4 — к ayw3, большинство проб подгенотипа D2 были подтипа ayw3, по 1 образцу было отнесено к подтипу ayw2 и ayw4. Все последовательности ДНК подгенотипа А2 относились к подтипу adw2.   Заключение. Выявленные у доноров варианты вируса гепатита В при филогенетическом анализе находились в одном кластере с ранее описанными последовательностями из Беларуси, что указывает на то, что эпидемиологический процесс по гепатиту В в стране поддерживается за счет местных «домашних» вирусов.</p></abstract><trans-abstract xml:lang="en"><p>   Objective. To determine the prevalence of markers of parenteral viral hepatitis B in donors of blood and its components in the Republic of Belarus.   Materials and methods. The study included 61 blood serum/plasma samples collected from donors from all regions of the country. All samples were examined by CLIA/ELISA and PCR for the presence of hepatitis B virus markers.   Results. As studies have shown, out of 61 sequenced samples, 58 (95.1 %) belonged to genotype D, and 3 (4.9 %) to A. Genotype D in 47 (81.1 %) cases was represented by the D2 subgenotype, in 5 (8.6 %) samples, the D1 subgenotype was detected, in 5 (8.6 %) — D3 and in 1 (1.7 %) sample the D4 subgenotype was detected, all samples of genotype A belonged to the A2 subgenotype. All DNA sequences of the D1 and D3 subgenotypes were assigned to the ayw2 subtype, D4 — to the ayw3 subtype, most samples of the D2 subgenotype were of the ayw3 subtype, and one sample each was assigned to the ayw2 and ayw4 subtypes. All DNA sequences of the A2 subgenotype belonged to the adw2 subtype.   Conclusion. The HBV variants identified in donors during phylogenetic analysis were in the same cluster with previously described sequences from Belarus, which indicates that the epidemiological process of hepatitis B in the country is supported by “local domestic” viruses.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>доноры</kwd><kwd>сыворотка/плазма крови</kwd><kwd>ИХЛ/ИФА</kwd><kwd>ПЦР</kwd><kwd>секвенирование</kwd><kwd>филогенетический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>donors</kwd><kwd>blood serum/plasma</kwd><kwd>CLIA/ELISA</kwd><kwd>PCR</kwd><kwd>sequencing</kwd><kwd>phylogenetic 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">The global burden of cancer: Priorities for prevention / M.
