В частности, не установлены гены, непосредственно обусловливающие вирулентность вируса для организма свиньи. Идентификация таких генов сделает возможным создание делетированных мутантных штаммов вируса АЧС, а также разработку и испытание экспериментальных безопасных вакцин на их основе. При изучении основ патогенности и иммуногенности вируса АЧС основным методом является сравнительный анализ биологических свойств вируса и выявление различий в структуре его генома, влияющих на определенные фенотипические признаки. Наиболее интересным и эффективным подходом к решению данной проблемы является анализ изменений структуры генов при адаптации вируса АЧС к репродукции в перевиваемой культуре клеток. Эти факторы обусловили необходимость получения варианта вируса АЧС, адаптированного к росту в перевиваемой культуре клеток. В процессе адаптации изолята Одинцово 02/14 вируса АЧС к репродукции в культуре клеток CV-1 удалось получить варианты вируса с измененными биологическими свойствами. При заражении свиней адаптированным вариантом вируса 30-го пассажа летальность составила 16,7%, причем все выжившие животные приобрели устойчивость к повторному заражению гомологичным вирулентным изолятом Arm 07. Следует отметить, что пассирование вируса в непермиссивной культуре клеток до 30 последовательных пассажей не привело к изменению его генотиповой принадлежности, однако в правой вариабельной концевой области генома появилась крупная делеция размером около 3000 п. н., аналогичная таковой в геноме штамма BA71V, адаптированного к росту в перевиваемой культуре клеток Vero.</p></abstract><trans-abstract xml:lang="en"><p>Functions of many African swine fever virus genes and multigene family members have not been yet understood. In particular, no virus genes directly associated with pig virulence have been identifed. Identifcation of such genes will enable preparation of deletion mutant ASF virus strains as well as development and testing of pilot safe vaccines based on the said virus strains. Comparative analysis of the virus biological characteristics and detection of diﬀerences in its genome structure aﬀecting certain phenotypic features is a main method used for the virus basic pathogenicity and immunogenicity examination. The most interesting and eﬀective approach to addressing this problem is an analysis of changes in the gene structure during ASF virus adaptation to replication in continuous cell culture. The said factors have made continuous cell culture-adapted variant ASF virus preparation necessary. Variant viruses with modifed biological features were prepared during adaptation of ASFV Odintsovo 02/14 isolate to replication in CV-1 cell culture. Lethality level was 16.7% when pigs were infected with adapted variant virus at 30th passage and survived animals became resistant to reinfection with homologous virulent ASFV Arm07 isolate. It should be noted that the virus passage in non-permissive cell culture up to 30 serial passages did not result in changes in its genotype; however, a large 3,000 bp deletion similar to that one in continuous Vero-cell culture-adapted BA71V strain genome appeared in right terminal variable region of the genome.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус африканской чумы свиней</kwd><kwd>адаптация</kwd><kwd>перевиваемая культура клеток CV-1</kwd><kwd>генотиповая принадлежность</kwd><kwd>биопроба</kwd><kwd>полногеномное секвенирование</kwd><kwd>генетическая структура</kwd><kwd>биологические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>African swine fever virus</kwd><kwd>adaptation</kwd><kwd>continuous CV-1 cell culture</kwd><kwd>genotyping</kwd><kwd>bioassay</kwd><kwd>whole genome sequencing</kwd><kwd>genetic structure</kwd><kwd>biological properties</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">Глик Б., Пастернак Дж.
