Ньюкаслская болезнь – высококонтагиозная вирусная инфекция птиц, которая регистрируется во многих странах мира. О случаях инфицирования вирусом ньюкаслской болезни необходимо уведомлять Всемирную организацию здравоохранения животных.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Проведение в течение 2023–2024 гг. на территории Российской Федерации мониторинговых исследований по ньюкаслской болезни с использованием серологических методов и анализ полученных результатов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Биологический материал (более 66 700 проб сыворотки крови птиц) был отобран территориальными управлениями Россельхознадзора в 74 субъектах Российской Федерации. Исследования выполнены на базе референтной лаборатории вирусных болезней птиц ФГБУ «ВНИИЗЖ»  (г. Владимир) с использованием диагностических наборов для выявления антител к вирусу ньюкаслской болезни иммуноферментным методом и в реакции торможения гемагглютинации производства ФГБУ «ВНИИЗЖ».</p></sec><sec><title>Результаты</title><p>Результаты. Проведенные исследования показали разную степень серопревалентности у сельскохозяйственной птицы промышленных птицеводческих хозяйств, индивидуального сектора и дикой птицы. Для кур и индеек в промышленных хозяйствах закрытого типа была установлена высокая серопревалентность по ньюкаслской болезни, что связано с массовой вакцинацией птиц против данного заболевания. При этом доля выявленной серопозитивной птицы (в целом по всем видам сельскохозяйственной птицы) была равна 74% в 2023 г. и 81% в 2024 г. В индивидуальном секторе антитела к вирусу ньюкаслской болезни были обнаружены в 35% случаев от числа всех исследованных проб сывороток крови кур и индеек в 2023 г. и в 53% случаев – в 2024 г.  Специфические антитела были выявлены также в пробах от вакцинированных цесарок и фазанов и от непривитых гусей и уток. В нескольких регионах Российской Федерации антитела к вирусу ньюкаслской болезни обнаружены у птиц дикой фауны, которые, вероятнее всего, являются естественным резервуаром возбудителя ньюкаслской болезни различной степени патогенности.</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, результаты мониторинговых исследований свидетельствуют о благополучной ситуации по ньюкаслской болезни в промышленных птицеводческих хозяйствах, обусловленной плановой вакцинацией поголовья. В то же время сохраняется угроза заноса и распространения ньюкаслской болезни птиц из неблагополучных индивидуальных хозяйств и дикой фауны.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Newcastle disease is a highly contagious viral infection of birds that is reported in many countries around the world. Newcastle disease cases shall be notified to the World Organization for Animal Health.</p></sec><sec><title>Objective</title><p>Objective. The objective of this research is to ensure monitoring of Newcastle disease using serological methods and analyze the findings obtained for 2023–2024 in the Russian Federation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The Territorial Administrations of Russian Federal Service for Veterinary and Phytosanitary Supervision sampled biological material in 74 subjects of the Russian Federation (more than 66,700 samples of avian sera). Tests for antibodies to Newcastle disease virus were conducted at the Reference Laboratory for Avian Viral Diseases, housed within the Federal Centre for Animal Health (Vladimir, Russia). Enzyme-linked  immunosorbent assay and hemagglutination inhibition assay were performed using diagnostic kits manufactured by the Federal Centre for Animal Health.</p></sec><sec><title>Results</title><p>Results. The conducted tests revealed significant variations of seroprevalence in commercial and backyards poultry flocks and in wild birds. High Newcastle disease virus seroprevalence was observed in chickens and turkeys within closed commercial farming systems due to routine mass vaccination against the disease. At the same time, the overall seropositivity rate for all poultry species was 74% in 2023, increasing to 81% in 2024. In backyards, antibodies to Newcastle disease virus were detected in 35% of all the tested sera samples from chickens and turkeys in 2023 and in 53% of the tested samples in 2024. Specific antibodies were also detected in samples from the vaccinated guinea fowl and pheasants and from non-vaccinated geese and ducks. Antibodies to Newcastle disease virus were also detected in wild birds across several Russian regions, suggesting their role of a natural reservoir for Newcastle disease virus strains of varying pathogenicity.</p></sec><sec><title>Conclusion</title><p>Conclusion. Therefore, the monitoring data indicate that routine flock vaccination helps to control successfully Newcastle disease in commercial poultry flocks, creating a stable epizootological situation. However, a significant risk of Newcastle disease virus introduction and spread from infected backyard poultry and wild bird reservoirs still persists.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ньюкаслская болезнь</kwd><kwd>эпизоотология</kwd><kwd>мониторинг</kwd><kwd>домашняя птица</kwd><kwd>дикая птица</kwd><kwd>синантропная птица</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Newcastle disease</kwd><kwd>epizootology</kwd><kwd>monitoring</kwd><kwd>poultry</kwd><kwd>wild birds</kwd><kwd>synanthropic birds</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания «Сбор и анализ эпизоотологических данных для оценки статусов благополучия субъектов Российской Федерации и страны в целом, в том числе для получения и поддержания статусов в соответствии с требованиями Кодекса наземных животных ВОЗЖ».</funding-statement><funding-statement xml:lang="en">This research was conducted under a state assignment “Collection and analysis of epizootic data for assessing animal health status of the Russian Federation Subjects and the country as a whole.
