В настоящее время в популяциях домашних и диких птиц в различных странах мира достаточно часто выявляют высоковирулентный вирус гриппа с нейраминидазой подтипа N8. В статье представлены данные по изучению полных нуклеотидных последовательностей гена нейраминидазы изолятов вируса высокопатогенного гриппа птиц, выделенных во второй половине 2020 г. из патологического материала, поступившего из четырех регионов Российской Федерации. В результате проведенных исследований определен подтип выделенного вируса – N8. Согласно данным филогенетического анализа, изоляты вируса N8 относятся к группе 8С.4. При проведении филогенетического анализа по нейраминидазе также учитывали данные классификации по гемагглютинину, согласно которой изоляты вируса Н5N8 относятся к широко распространенной кладе 2.3.4.4. Вирусы данной клады впервые зарегистрированы в 2010 г. в Китае и продолжают циркулировать до настоящего времени. Также в работе приведены данные сравнительного анализа нуклеотидных последовательностей исследуемых изолятов и изолятов из международных баз данных GenBank и GISAID, выделенных в других странах в период с 2007 по 2020 г. В ходе про- ведения анализа аминокислотной последовательности исследуемых изолятов в позициях, которые влияют на резистентность к ингибиторам нейрамини- даз, замен не обнаружено. Полные нуклеотидные последовательности гена нейраминидазы вируса гриппа птиц подтипа N8 изолятов A/domestic goose/ Omsk/1521-1/2020, A/duck/Chelyabinsk/1207-1/2020, A/duck/Saratov/1578-2/2020, A/goose/Tatarstan/1730-2/2020 опубликованы в международных базах GenBank и GISAID. На основании анализа нуклеотидных последовательностей изученных изолятов показана постепенная эволюция вируса подтипа N8.</p></abstract><trans-abstract xml:lang="en"><p>Avian influenza is a highly dangerous viral disease that causes huge economic damage to poultry farming. Currently, highly virulent influenza virus with N8 neur- aminidase subtype is quite often detected in populations of domestic and wild birds in various countries of the world. The article provides data on complete nucleotide sequences of the neuraminidase gene of highly pathogenic avian influenza virus isolates recovered in the second half of 2020 from pathological material received from four regions of the Russian Federation. The conducted research showed that the subtype of the isolated virus was N8. According to the phylogenetic analysis, isolates of N8 virus belong to group 8C.4. During the phylogenetic analysis of the neuraminidase, we also took into account data on hemagglutinin classification, according to which H5N8 virus isolates belong to a widespread clade 2.3.4.4. Viruses of the clade were first registered in 2010 in China and they have been circulating up to now. The paper also provides data of a comparative analysis of nucleotide sequences of the studied isolates and the isolates from the international GenBank and GISAID databases, recovered in other countries from 2007 to 2020. During the analysis of the amino acid sequence of the studied isolates, no substitutions were found in the positions that affect resistance to neuraminidase inhibitors. The complete nucleotide sequences of the neuraminidase gene of the avian influenza virus subtype N8 (isolates A/domestic goose/OMSK/1521-1/2020, A/duck/Chelyabinsk/1207-1/2020, A/duck/Saratov/1578-2/2020, A/goose/Tatarstan/1730-2/2020) are published in the international GenBank and GISAID databases. Based on the analysis of the nucleotide sequences of the studied isolates, the article shows gradual evolution of the N8 subtype virus.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус гриппа птиц</kwd><kwd>ОТ-ПЦР</kwd><kwd>секвенирование</kwd><kwd>подтип нейраминидазы N8</kwd><kwd>филогенетический анализ</kwd><kwd>H5N8</kwd></kwd-group><kwd-group xml:lang="en"><kwd>avian influenza virus</kwd><kwd>RT-PCR</kwd><kwd>sequencing</kwd><kwd>N8 neuraminidase subtype</kwd><kwd>phylogenetic analysis</kwd><kwd>H5N8</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств ФГБУ «ВНИИЗЖ» в рамках тематики научно-исследовательских работ «Ветеринарное благополучие»</funding-statement><funding-statement xml:lang="en">The study was funded by the FGBI “ARRIAH” within the framework of “Veterinary Welfare” research work</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Swayne D.
