For the routine evaluation the anti-rabies vaccination effectiveness, World Organization for Animal Health (OIE) recommends various enzyme-linked immunosorbent assays (ELISA).</p> <p><bold>The aim </bold>of the study was to design and validate a competitive ELISA (cELISA) test system for the detection of antibodies to the rabies virus (RABV).</p> <p><bold>Materials and methods.</bold> The development of the cELISA was carried out following the OIE recommendations.</p> <p><bold>Results.</bold> The repeatability of the cELISA results within one laboratory was satisfactory (coefficient of variation 7.95–13.61%). The coefficient of determination (CD) between the results of the virus neutralization reaction (FAVN) and cELISA was 0.988, <italic>p</italic> &lt; 0.001. The lower threshold for antibody detection was less than 0.02 IU/ml. The cELISA did not demonstrate cross-reactivity against antibodies to canine distemper virus, parainfluenza virus, parvovirus, coronavirus, and canine adenovirus (types I and II). During the study of 137 dog blood sera, diagnostic specificity (DSp) and diagnostic sensitivity (DSe) for the cELISA were 83.1% and 94.9%, respectively, and CD between the cELISA and FAVN results was 0.968, p &lt; 0.001.</p> <p><bold>Discussion.</bold> Indirect ELISA test systems for determining the level of antibodies to RABV are not sensitive enough compared to reference tests, unlike cELISA. The developed test system is not inferior for its DSp and DSe to the commercial cELISA BioPro ELISA Rabies Ab (DSp 66.7%, DSe 94.4%).</p> <p><bold>Conclusion.</bold> The developed cELISA test system can be used to detect antibodies to RABV in the blood serum of dogs for evaluating the effectiveness of mass vaccination programs.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Основным направлением профилактики бешенства является вакцинация домашних и диких плотоядных животных. Для рутинной оценки эффективности антирабической вакцинации Международным эпизоотическим бюро (МЭБ) рекомендован иммуноферментный анализ (ИФА). Актуальной задачей остаётся разработка модификаций ИФА с большей диагностической специфичностью (ДС) и чувствительностью (ДЧ).</p> <p><bold>Цель работы</bold> – конструирование и валидация тест-системы на основе конкурентного ИФА (кИФА) для выявления антител к вирусу бешенства (ВБ).</p> <p><bold>Материалы и методы.</bold> Разработку тест-системы проводили в соответствии с рекомендациями МЭБ. Определяли дозу ВБ для сенсибилизации планшетов, состав блокирующего буфера; оптимальные разведения компонентов; порядок интерпретации результатов ИФА.</p> <p><bold>Результаты.</bold> Повторяемость результатов кИФА в рамках одной лаборатории была удовлетворительной: коэффициент вариации – 7,95–13,61%, коэффициент детерминации (КД) между результатами реакции нейтрализации (FAVN) и кИФА – 0,988, <italic>p</italic> &lt; 0,001. Нижний порог обнаружения антител составил менее 0,02 МЕ/мл. Разработанная тест-система не демонстрировала кросс-реактивности в отношении антител к вирусу чумы плотоядных, вирусу парагриппа, парвовирусу, коронавирусу, аденовирусу собак (I и II серотипа). При исследовании 137 сывороток крови собак ДС и ДЧ кИФА составили 83,1 и 94,9% соответственно, КД между результатами кИФА и FAVN – 0,968, <italic>p</italic> &lt; 0,001.</p> <p><bold>Обсуждение. </bold>Диагностикумы для определения уровня антител к ВБ на основе непрямого ИФА недостаточно чувствительны по сравнению с референс-тестами. Оптимальным решением являются варианты кИФА с применением биотинилированных антител. Разработанная тест-система по ДС и ДЧ не уступает коммерческой тест-системе кИФА BioPro ELISA Rabies Ab: ДС 66,7%, ДЧ 94,4%.</p> <p><bold>Заключение.</bold> Таким образом, разработанная тест-система на основе кИФА может быть использована для выявления антител к ВБ в сыворотке крови собак при оценке эффективности программ массовой вакцинации.</p></trans-abstract><kwd-group xml:lang="en"><kwd>rabies</kwd><kwd>antibodies/analysis</kwd><kwd>nzyme-linked immunosorbent assay/methods</kwd><kwd>enzyme-linked immunosorbent assay/veterinary</kwd><kwd>sensitivity and specificity</kwd><kwd>ROC curve</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>бешенство</kwd><kwd>выявление антител</kwd><kwd>конкурентный иммуноферментный анализ</kwd><kwd>диагностическая специфичность</kwd><kwd>диагностическая чувствительность</kwd><kwd>ROC-анализ</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Государственный бюджет</institution></institution-wrap><institution-wrap><institution xml:lang="en">The state budget</institution></institution-wrap></funding-source><award-id>FZFU-2019-0013</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>OIE Manual of Diagnostic Tests and Vaccines for Terrestrial Animals – 2018.
