The investigators analyzed 41 samples of the viruses obtained in 2005-2007. Polymorphism at codons associated with integrase resistance to chemicals was observed in 11 virus variants. The circulation of mutation viruses that potentially promote the formation of resistance to the integrase inhibitors raltegravir and elvitegravir has been established in untreated patients.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены данные изучения генетического полиморфизма гена pol, кодирующего вирусную интегразу, популяции ВИЧ-инфицированных субтипом G, сформировавшейся в результате внутрибольничной вспышки ВИЧ-инфекции в 1989 г. В работе исследовали 41 образец вирусов, полученных с 2005 по 2007 г. Полиморфизм в кодонах, связанных с формированием устойчивости интегразы к химиопрепаратам, наблюдали у 11 вариантов вируса. Установлен факт циркуляции в популяциях вирусов мутаций у нелеченых пациентов, потенциально способствующих формированию резистентности к ингибиторам интегразы: ралтегравиру и элвитегравиру.</p></trans-abstract><kwd-group xml:lang="en"><kwd>genetic polymorphism</kwd><kwd>HIV infection</kwd><kwd>integrase</kwd><kwd>subtype G</kwd><kwd>raltegravir</kwd><kwd>elvitegravir</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>генетический полиморфизм</kwd><kwd>ВИЧ-инфекция</kwd><kwd>интеграза</kwd><kwd>субтип G</kwd><kwd>ралтегравир</kwd><kwd>элвитегравир</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Пазилин А.
