В Республике Беларусь эпизоотический мониторинг ВГЕ-инфекции является недостаточным ввиду отсутствия необходимого количества доступных и недорогих диагностических ИФА тест-систем с хорошей чувствительностью и специфичностью. В этой связи проведение исследований по разработке отечественной тест-системы для полуколичественного выявления антител к вирусу гепатита Е у свиней с последующей оценкой серопревалентности к ВГЕ в популяции свиней в Республике Беларусь является актуальным. В статье представлены результаты исследований по разработке иммуноферментной тест-системы для полуколичественного определения иммуноглобулинов класса G к ВГЕ в сыворотке крови свиней с использованием рекомбинантных белков, включающих иммунодоминантные аминокислотные последовательности, соответствующие белкам ОRF2 и ОRF3 ВГЕ 3-го генотипа. Определена оптимальная концентрация для сорбции белков ОRF2 и ОRF3 – 2 и 1 мкг/мл соответственно. Диагностическая чувствительность данной тест-системы составляет 94,8 %, а диагностическая специфичность – 100 %. Коэффициенты вариации, являющиеся критерием оценки внутрисерийной и межсерийной воспроизводимости данной тест-системы, составляют 3,5 и 12,4 % соответственно, что позволяет получать воспроизводимые результаты и выявлять специфические антитела к ВГЕ во всех положительных образцах сывороток крови свиней. При исследовании 1235 проб сывороток свиней из разных свиноводческих хозяйств Брестской, Витебской, Гомельской, Гродненской, Минской и Могилевской областей антитела к антигенам вируса гепатита Е (ВГЕ) были обнаружены у 168, или у 13,6 % животных. Описанный метод диагностики может найти широкое применение для науки и практики с целью дальнейшего изучения серопревалентности анти-ВГЕ. Благодарности.

Epizootic monitoring of HEV infection is insufficient in the Republic of Belarus due to lack of the required number of available and inexpensive diagnostic ELISA kits with good sensitivity and specificity. In this regard, research on development of domestic ELISA kit for semi-quantitative detection of antibodies to hepatitis E virus in pigs with subsequent assessment of seroprevalence to HEV in pig population in the Republic of Belarus is relevant. The results of studies on development of enzyme-linked immunosorbent assay kit for semi-quantitative determination of class G immunoglobulins to HEV in pig blood serum using recombinant proteins, including immunodominant amino acid sequences corresponding to the ORF2 and ORF3 proteins of HEV genotype 3 are presented in the paper. The optimal concentration for sorption of ORF2 and ORF3 proteins has been determined, which is 2 μg/ml and 1 μg/ml, respectively. The diagnostic sensitivity of this test kit makes 94.8 %, and the diagnostic specificity makes 100 %. Coefficients of variation being the criterion for assessing the intra-serial and inter-serial reproducibility of this test kit, make 3.5 % and 12.4 %, respectively, which allows to obtain reproducible results and identify specific anti-HEV antibodies in all positive samples of pig blood serum. When studying 1235 pig sera samples from various pig farms of Brest, Vitebsk, Gomel, Grodno, Minsk and Mogilev regions, seroprevalence of anti-HEV antibodies has been determined in 168 or 13.6 % of animals. The described diagnostic method can be widely used in science and practice for the further study of seroprevalence of anti-HEV. Acknowledgments.
