В итоге зарегистрировано 17 неблагополучных пунктов, где содержалось невакцинированное поголовье в личных подсобных хозяйствах граждан. В данной работе оценивали иммуногенность вакцин производства ФГБУ «ВНИИЗЖ», а также эффективность различных схем вакцинации для профилактики ньюкаслской болезни в отношении актуальных для Российской Федерации вирусов VII генотипа. Известно, что вирулентность циркулирующего в настоящее время возбудителя ньюкаслской болезни заметно возросла по сравнению с вирусами, выделенными в предыдущие годы, и он способен преодолевать поствакцинальный иммунитет, создаваемый живыми вакцинами. В результате исследований было установлено, что вакцины производства ФГБУ «ВНИИЗЖ» обладают высокой иммуногенной активностью в отношении вирусов VII генотипа, что позволяет эффективно профилактировать эту болезнь при их использовании в составе стандартных схем вакцинации. Схема вакцинации с двукратным применением живой вакцины из штамма «Ла-Сота» формирует иммунитет у 100% цыплят, так же как и «полная» схема вакцинации с использованием инактивированных вакцин. Применение живых вакцин в схеме вакцинации с однократным и двукратным введением предотвращает гибель птиц и клиническое проявление болезни, однако не препятствует репликации вируса, в то время как добавление в схему иммунизации инактивированной вакцины предотвращает, кроме того, и репликацию вирулентного вируса. Таким образом, использование живых и инактивированных вакцин отечественного производства, прежде всего на основе штамма «Ла-Сота», с последующим контролем напряженности иммунитета и проведением ревакцинаций по показаниям является главным инструментом в борьбе с заболеванием.</p></abstract><trans-abstract xml:lang="en"><p>In 2019, the situation regarding Newcastle disease in the Russian Federation worsened radically due to the spread of NDV subgenotype VII-L throughout the country from the Primorsky Krai to the Kursk Oblast. As a result, 17 infected settlements with backyard farms where unvaccinated poultry was kept were registered. In this study, immunogenicity of the vaccines produced by the FGBI “ARRIAH”, as well as the effectiveness of various vaccination schedules to prevent genotype VII NDVs, relevant for the Russian Federation, was studied. It is known that the currently circulating ND agent is significantly more virulent compared to the viruses isolated in previous years, and it is able to bypass the immunity provided by live vaccines. Test results demonstrated that the vaccines against genotype VII NDVs produced by the FGBI “ARRIAH” are highly immunogenic, which allows to effectively prevent the disease when using them as part of a standard vaccination schedule. A 2-dose vaccination schedule using live vaccine from the La Sota strain as well as the “complete” vaccination schedule using inactivated vaccines provides immunity in 100% of chicks. The use of live vaccines in a single- and double-dose vaccination schedules prevents mortality and clinical disease in poultry, but does not prevent virus replication, while the addition of an inactivated vaccine to the immunization schedule does prevent the replication of the virulent virus. Thus, the use of domestically produced live and inactivated vaccines, primarily the ones containing the La Sota strain, with the following control of the immunity level and booster vaccination, if required, is the main tool for the disease control.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Вирулентный вирус ньюкаслской болезни VII генотипа</kwd><kwd>вакцины против ньюкаслской болезни</kwd><kwd>эффективность вакцин против ньюкаслской болезни</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Virulent genotype VII Newcastle disease virus</kwd><kwd>ND vaccines</kwd><kwd>effectiveness of ND vaccines</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств ФГБУ «ВНИИЗЖ» в рамках научно-исследовательских работ по теме «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">Alexander D.
