Evaluate prevalence of genetic variants of hepatitis В viruses in population of various regions of Uzbekistan with hepatitis of various genesis and different severity levels of liver fibrosis and cirrhosis. Materials and methods. Blood plasma and liver biopsy from 39 patients with different severity levels of liver fibrosis and cirrhosis served as study material. Genotyping based on direct sequencing of Pre-Sl/Pre-S2/S HBV DNA region was applied. Results. Hepatitis В virus was detected in 32 samples ofthe 39 provided, frequency of occurrence - 82%, respectively. Phylogenetic analysis has shown, that only genotype D was detected among the examined patients, hepatitis В virus subtype D1 predominated (84.38%) compared with D2 (3.12%) and D3 (12.5%) subtypes. Conclusion. Large-scale sequencing of HBV in Central Asia will allow to evaluate routes of transmission and time of evolutionary separation of virus isolates. Understanding the epidemiology of the infectious process is important for development of programs for prophylaxis and therapy of the infection.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Оценить распространенность генетических вариантов вируса гепатита В у жителей из различных регионов Узбекистана, страдающих гепатитами разного генеза с различной степенью выраженности фиброза печени и циррозом. Материалы и методы. Материалом исследования служили плазма крови и биоптаты печени 39 пациентов с различной степенью выраженности фиброза печени и циррозом. Было применено генотипирование на основе прямого секвенирования Pre-Sl/Pre-S2/S области ДНК ВГВ. Результаты. Вирус гепатита В был выявлен в 32 образцах из представленных 39, частота встречаемости - 82% соответственно. На основании филогенетического анализа показано, что среди обследованных больных выявлен только генотип D, преобладал вирус гепатита В субтипа D1 (84,38%) по сравнению с субтипами D2 (3,12%) и D3 (12,5%). Заключение. Масштабное скринирование ВГВ в Центральной Азии позволит оценить пути распространения и время эволюционного разделения изолятов вируса. Понимание эпидемиологии инфекционного процесса важно для разработки программ по профилактике и лечению инфекции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hepatitis B</kwd><kwd>deep genotyping</kwd><kwd>sequencing</kwd><kwd>molecular epidemiology</kwd><kwd>Uzbekistan</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гепатит В</kwd><kwd>глубокое генотипирование</kwd><kwd>секвенирование</kwd><kwd>молекулярная эпидемиология</kwd><kwd>Узбекистан</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>ДамиНовТА., Камилов А.И., Туйчиев Л.Н. идр.
