Заболеваемость собак инфекционным ларинготрахеитом наиболее часто регистрируется в центральной части Российской Федерации и имеет тенденцию к росту. В связи с этим сохраняется актуальность профилактической иммунизации против данного заболевания. В первую очередь для формирования длительного и напряженного иммунитета у животных при изготовлении вакцины необходимо использовать штаммы вируса, распространенные на конкретной территории и актуальные на данный отрезок времени. Целью данного исследования являлось выделение возбудителя аденовироза собак 2-го типа из биологического материала от животных с признаками аденовирусной инфекции, обладающего устойчивостью на протяжении пяти и более пассажей, а также определение параметров его культивирования. В результате эксперимента было выделено пять изолятов вируса, один из которых обладал оптимальными свойствами для использования при производстве вакцинных препаратов. При проведении сравнительного анализа чувствительности к выделенному вирусу перевиваемых культур клеток Vero, MDCK линий NBL-2 и NBL-9, а также первично трипсинизированных культур клеток (почка щенка, селезенка щенка, почка котенка, селезенка котенка) было установлено, что наиболее чувствительной является клеточная культура MDCK линии NBL-2. Следующим этапом было определение параметров культивирования вируса в данной культуре клеток. В результате установлены оптимальные условия, при которых происходит накопление вируса в максимальных титрах: возраст монослоя культуры клеток для заражения – 48 ч, множественность заражения – 0,01 ТЦД50/кл, время предварительного контакта – 60 мин, температура – (37,0 ± 0,5) °С, срок культивирования – 120 ч.</p></abstract><trans-abstract xml:lang="en"><p>Adenovirus infection in dogs caused by canine adenovirus serotype 2 predominantly results in respiratory disease typically manifested by respiratory tract lesions. Infectious laryngotracheitis is the most often recorded in dogs in the central part of the Russian Federation and its incidence tends to increase. Therefore, preventive immunization against this disease remains important. Primarily, the virus strains currently important and circulating in the particular territory shall be used for vaccine production to induce long-term and strong immunity in animals. The study was aimed at isolation of canine adenovirus type 2 remaining stable during five or more passages from the biological samples collected from animals with adenovirus infection signs as well as at determination of its cultivation parameters. As a result, five virus isolates were recovered, one of the recovered virus isolates had optimal properties for its use for vaccine production. Comparative analysis of continuous Vero, MDCK (NBL-2 and NBL-9 line) cell cultures as well as primarily trypsinized cell cultures (baby dog kidney, baby dog spleen, baby cat kidney, baby cat spleen) for their susceptibility to the recovered virus showed that MDCK (NBL-2 line) was the most susceptible. The virus cultivation parameters in this cell culture was determined at the next step. The following optimal conditions under which the virus accumulated to the maximum titres were determined: cell culture monolayer age for inoculation – 48 hours, multiplicity of infection – 0.01 TCID50/cell, preliminary holding time – 60 min, temperature – (37.0 ± 0.5) °С, cultivation period – 120 hours.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аденовирус собак 2-го серотипа</kwd><kwd>выделение изолята</kwd><kwd>аденовирусная инфекция</kwd><kwd>инфекционная активность вируса</kwd><kwd>параметры культивирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>canine adenovirus serotype 2</kwd><kwd>recovery of isolate</kwd><kwd>adenovirus infection</kwd><kwd>virus infectivity</kwd><kwd>cultivation parameters</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">Савина Н.
