Аннотация

Цель. Эспериментальное воспроизведение ВГЕ-инфекции на домашних карликовых свиньях (минипигах) и сравнительный анализ вирусологических и иммунологических характеристик экспериментальной инфекции. Материалы и методы. Минипиги породы Визенау (2 самки и 4 самца возрастом 50 - 60 дней и весом 5 - 10 кг) были инфицированы штаммом В ГЕ генотипа 3, выделенным из фекалий свиней в Белгородской обл. в 2013 г. Вирус вводили в виде 10% осветленного фекального экстракта (800 мкл). В течение 49 дней эксперимента у животных брали кровь (еженедельно) и фекалии ежедневно. Анти-ВГЕ IgG определяли в образцах сыворотки крови с помощью тест-системы ДС-ИФА-ANTI-HEV-G (Диагностические системы), РНК ВГЕ в образцах фекальных экстрактов и в сыворотке крови - в ОТ-ПЦР. Результаты. Минипиги породы Визенау оказались восприимчивы к заражению ВГЕ генотипа 3, у всех животных после введения вируса развилась инфекция, сопровождавшаяся присутствием РНК ВГЕ в фекалиях на протяжении двух недель и сероконверсией по анти-ВГЕ. Сравнительный анализ вирусологических характеристик экспериментальной ВГЕ-инфекции у миниатюрных и стандартных свиней показал, что у минипигов продолжительность инфекции короче, а сероконверсия по анти-ВГЕ происходит раньше. Заключение. Восприимчивость к ВГЕ генотипа 3 и меньший вес делают карликовых свиней удобной альтернативой обычным домашним свиньям и приматам для моделирования ВГЕ-инфекции in vivo.

Abstract

Aim. Experimental reproduction of HEV-infection in mini-pigs and comparative analysis of virological and immunological characteristics of experimental infection. Materials and methods. Wiesenauer minipigs (2 females and 4 males, age 50 - 60 days, weight 5-10 kg) were infected by HEV genotype 3 strain isolated from swine feces in Belgorod region in 2013. The virus was administered as a 10% clarified feces extract (800 pi). Blood (weekly) and feces (daily) were sampled from the animals for 49 days. Anti-HEV IgG were determined in sera samples using DS- ElA-ANTI-HEV-G (Diagnostic Systems) system, HEV RNA in samples of feces extracts and blood sera - RT-PCR. Results. Wiesenauer minipigs were sensitive to HEV genotype 3 infection, infection developed in all the animals after administration of the virus, that was accompanied by the presence of HEV RNA in feces for 2 weeks and seroconversion by anti-HEV. Comparative analysis of virological characteristics of experimental H EV-infection in mini- and standard pigs has shown, that the duration of the infection in mini-pigs is shorter, and seroconversion by anti-HEV occurs earlier. Conclusion. Sensitivity to HEV genotype 3 and lower weight make mini-pigs a comfortable alternative to standard swine and primates for modelling HEV infection in vivo.
