Ньюкаслская болезнь регистрируется во многих странах мира, иногда принимая характер эпизоотии. Активно циркулирующий в последние годы вирус ньюкаслской болезни генотипа VII отличается высокой вирулентностью и вызывает беспокойство в силу способности активно мутировать. В условиях интенсивного птицеводства важно уделять особое внимание вопросам специфической профилактики данной болезни и применять эффективные вакцины для защиты птицепоголовья.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Определить иммуногенную активность трех инактивированных вакцин против ньюкаслской болезни птиц при контрольном заражении цыплят вирусом ньюкаслской болезни генотипа VII.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследованы три вакцины против ньюкаслской болезни: моновалентная (антиген «Ла-Сота»), «ВНИИЗЖ-АвиНью Мульти» и «ВНИИЗЖ-АвиНьюФлу Мульти» (антигены «ВНИИЗЖ G7» и «Ла-Сота»). Антигены разбавляли физиологическим раствором в соотношениях 1:25, 1:50, 1:100 или использовали неразведенными, затем эмульгировали с адъювантом Coralvac RZ 528. Каждый образец соответствующей вакцины вводили 10 цыплятам яичного кросса 4-недельного возраста внутримышечно в область груди в объеме 0,5 см3. Контрольную группу не вакцинировали. Через 28 сут определяли титр поствакцинальных антител в реакции торможения гемагглютинации и проводили контрольное заражение вирулентным штаммом вируса ньюкаслской болезни генотипа VII.</p></sec><sec><title>Результаты</title><p>Результаты. Все исследуемые препараты вызывали формирование напряженного поствакцинального иммунитета к вирусу ньюкаслской болезни спустя 28 сут после введения птицам, а также соответствовали требованиям Всемирной организации здравоохранения животных. Тем не менее вакцины «ВНИИЗЖ-АвиНью Мульти» и «ВНИИЗЖ-АвиНьюФлу Мульти» показали более высокий уровень протективного действия при контрольном заражении изолятом вируса ньюкаслской болезни генотипа VII в сравнении с моновалентной вакциной из антигена «Ла-Сота».</p></sec><sec><title>Заключение</title><p>Заключение. Поливалентные вакцины «ВНИИЗЖ-АвиНью Мульти» и «ВНИИЗЖ-АвиНьюФлу Мульти», изготовленные на основе смеси антигенов вируса ньюкаслской болезни генотипов II и VII, обеспечивают высокую степень защиты цыплят и могут использоваться для профилактики ньюкаслской болезни, вызванной вирусами генотипа VII.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Newcastle disease (ND) is reported in many countries worldwide, where it sometimes assumes an epizootic nature. Newcastle disease virus (NDV) genotype VII, which has been actively circulating in recent years, is highly virulent and raises concern due to its ability to undergo rapid mutation. In the context of intensive poultry farming, special attention must be paid to the specific prevention of this disease, including the use of effective vaccines to protect poultry flocks.</p></sec><sec><title>Objective</title><p>Objective. To determine the immunogenic activity of three inactivated Newcastle disease vaccines in chickens following challenge with NDV genotype VII.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Three vaccines against Newcastle disease were tested: a monovalent vaccine (LaSota antigen), ARRIAH-AviNew Multi, and ARRIAH-AviNew-Flu Multi (containing ARRIAH G7 and LaSota antigens). The antigens were diluted with saline solution at ratios of 1:25, 1:50, and 1:100 or used undiluted, and then emulsified with Coralvac RZ 528 adjuvant. Each vaccine sample was administered at a volume of 0.5 cm³ intramuscularly into the pectoral muscle to 10 four-week-old egg-type chickens per group. The control group remained unvaccinated. The antibody titers were determined using the hemagglutination inhibition test at day 28 post-vaccination, and the chickens were challenged with a virulent strain of NDV genotype VII.</p></sec><sec><title>Results</title><p>Results. All tested vaccines induced strong post-vaccination immunity against NDV by day 28 post inoculation to birds and met the requirements of the World Organisation for Animal Health. However, the ARRIAH-AviNew Multi and ARRIAH-AviNewFlu Multi vaccines demonstrated a higher level of protective efficacy following challenge with an NDV genotype VII isolate compared to the monovalent vaccine based on LaSota antigen.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ньюкаслская болезнь</kwd><kwd>вирус ньюкаслской болезни генотипа VII</kwd><kwd>инактивированные вакцины</kwd><kwd>иммуногенная активность</kwd><kwd>PD50</kwd><kwd>гуморальный иммунитет</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Newcastle disease</kwd><kwd>Newcastle disease virus genotype VII</kwd><kwd>inactivated vaccines</kwd><kwd>immunogenic activity</kwd><kwd>PD50</kwd><kwd>humoral immunity</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».
