Материалом для исследования послужили 2616 проб сыворотки крови жителей Гвинейской Республики. Пациенты были обследованы на наличие маркеров ВГВ: HBsAg, HBs IgG и HBCore IgG. Нуклеотидные последовательности полного генома ВГВ были получены для 298 образцов, включая пациентов с коинфекцией ВИЧ/ВГВ. Амплификацию и последующее секвенирование вируса проводили с использованием вложенной ПЦР с парными перекрывающимися праймерами, совместно фланкирующими полный геном ВГВ (гены S, P, C, X).Результаты. Серологические маркеры ВГВ выявлены в 80,77% проб, HBsAg — у 16,01% обследованных. ДНК ВГВ выявили в 22,36% случаев. Распространенность HBsAg-отрицательного ВГВ у пациентов с РНК ВИЧ составляет 45,16%, что значительно выше, чем в группе без ВИЧ-инфекции (6,07%). В обследованной группе преобладал ВГВ генотипа Е — 75,5%, по сравнению с D1 — 9,39%, D2 — 4,02%, D3 — 6,37%, A2 — 4,7%. Вариабельность аминокислот среди образцов ВГВ была выше в регионе PreCore/Core, чем в регионе PreS1/PreS2/S. Мутации SHB были обнаружены в 83,89% случаев, мутации Core у 94,29%, замены аминокислот PreCore у 16,77% пациентов соответственно. Результаты, полученные в этой работе, демонстрируют высокую распространенность ВГВ в регионе и указывают на необходимость дальнейших крупномасштабных исследований мутаций ВГВ с целью улучшения стратегий контроля и профилактики заболеваний в Гвинейской Республике.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to characterize the genetic variants of HBV currently circulating in the Republic of Guinea, based on the nucleotide sequences of the complete virus genome, and to analyze clinically significant mutations in the Core and HBsAg regions during HBV monoinfection and HBV/HIV coinfection.Materials and methods. The study material was represented by 2616 blood serum samples collected from residents of the Republic of Guinea. The subjects were examined for the presence of HBV markers with a qualitative detection of HBsAg, HBs IgG, and HBCore IgG. HBV complete genome nucleotide sequences were obtained for 298 samples including HIV/HBV coinfected patients. Amplification and subsequent sequencing of HBV were performed using nested PCR with pair’s overlapping primers jointly flanking the complete HBV genome (S, P, C, X genes).Results. HBV serological markers were detected in 80.77% samples, while HBsAg was detected in 16.01% of the examined group. HBV DNA we detected in 22.36%. The prevalence of HBsAg-negative HBV in patients with HIV RNA is 45.16%, which is significantly higher than 6.07% found in the group without HIV infection. Phylogenetic analysis of HBV in the examined samples showed that HBV genotype E (75.5%) predominates in the group compared to HBV genotype D1 (9.39%), D2 (4.02%), D3 (6.37%), and A2 (4.7%). In the tested group, the variability of amino acids among the HBV samples was higher in the PreCore/Core region than in the PreS1/PreS2/S region. SHB mutations were detected in 83,89%, Core mutations in 94.29%, PreCore amino acid substitutions in 16.77% of the patients, respectively.The results obtained in this work demonstrate a high prevalence of HBV in the region and indicate the need for further largescale studies of HBV mutations in order to improve strategies for disease control and prevention in the Republic of Guinea.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ВГВ</kwd><kwd>генотипы</kwd><kwd>аминокислотные замены</kwd><kwd>мутации вакцинного бегства</kwd><kwd>мутации лекарственной устойчивости</kwd><kwd>молекулярная эпидемиология</kwd><kwd>Гвинейская Республика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HBV</kwd><kwd>genotypes</kwd><kwd>amino acid substitutions</kwd><kwd>vaccine escape mutations</kwd><kwd>drug resistance mutations</kwd><kwd>molecular epidemiology</kwd><kwd>Republic of Guinea</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">Schweitzer A., Horn J., Mikolajczyk R.T., Krause G., Ott J.J.
