В качестве иммуногенов использовали рекомбинантный вирус осповакцины, экспрессирующий трансген поверхностного гликопротеина (GP) MARV штамма Musoke, и псевдовирусные частицы, экспонирующие GP трех штаммов MARV: Popp, Musoke и DRC2000, – на основе лентивируса и рекомбинантного штамма вируса везикулярного стоматита (VSV). В иммунизации участвовало две группы птиц. Кур иммунизировали девять раз: в первый раз вводили рекомбинантный вирус осповакцины, а затем 8 раз – псевдовирусные частицы (на основе лентивируса и рекомбинантного штамма вируса везикулярного стоматита). Первую группу иммунизировали очищенным и концентрированным иммуногеном, а вторую группу им же, но в комплексе с неполным адъювантом Фрейнда. Накопление специфических антител оценивали методом иммуноферментного анализа (ИФА). Для анализа накопления нейтрализующих антител использовали рекомбинантный VSV, экспонирующий GP MARV, и натуральный MARV штамма Popp.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Разработана эффективная схема иммунизации кур тремя рекомбинантными конструктами, презентирующими GP MARV, в результате которой происходит индукция куриных антител класса IgY против вируса Марбург с титром в ИФА от 1:100 до 1:1 млн. Полученные IgY нейтрализуют псевдовирусы MARV (штаммы Popp, DRC2000, Musoke) в разведении от 1/256 до 1/1024 и натуральный вирус MARV штамма Popp в разведении 1/8. Более стабильные результаты продемонстрировала схема иммунизации с использованием неполного адъюванта Фрейнда. </p></sec></abstract><trans-abstract xml:lang="en"><p>The aim was to study the possibility of inducing Marburg-neutralizing chicken antibodies (MARV) using various immunogens.</p><sec><title>Materials and methods</title><p>Materials and methods. Recombinant vaccinia virus expressing the surface glycoprotein (GP) transgene MARV of Musoke strain and pseudovirus particles exhibiting GP of three strains of MARV – Popp, Musoke and DRC2000 based on lentivirus and recombinant strain of vesicular stomatitis virus (VSV) were used as immunogens. Two groups of birds were involved in the study. Chickens were immunized 9 times: first time they were injected with the recombinant vaccinia virus, and then 8 times – with pseudovirus particles (based on lentivirus and a recombinant strain of the vesicular stomatitis virus). The accumulation of specific antibodies was evaluated by enzyme-linked immunosorbent assay (ELISA). We used recombinant VSV exhibiting GP MARV, and natural MARV strain Popp for the analysis of accumulation of neutralizing antibodies.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. We have developed an effective immunization schedule for chickens with three recombinant constructs presenting GP MARV, which results in the induction of chicken IgY antibodies against Marburg virus with a titer in ELISA from 1:100 to 1:1 million. The obtained IgY neutralize MARV pseudoviruses (Popp, DRC2000, Musoke) at a dilution of 1/256 to 1/1024 and the natural MARV virus of the Popp strain at a dilution of 1/8. More stable results were demonstrated by immunization using Freund’s incomplete adjuvant. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус Марбург</kwd><kwd>антитела</kwd><kwd>IgY</kwd><kwd>вирусоподобные частицы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Marburg virus</kwd><kwd>antibodies</kwd><kwd>IgY</kwd><kwd>virus-like particles</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта №18-34-00512 мол_а.</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">Geisbert T.W., Hensley L.E., Kagan E., Yu E.Z., Geisbert J.B., Daddario-DiCaprio K., Fritz E.A., Jahrling P.B., McClintock K., Phelps J.R., Lee A.C.H., Judge A., Jeffs L.B., MacLachlan I.
