Распространение гепатита е у свиней в Могилевской и Минской областях Республики Беларусь

Abstract

В статье представлены результаты исследования сывороток крови свиней животноводческих ферм и частного сектора выращиваемых на территории Могилевской и Минской областей Беларуси (n=625) на наличие антител к вирусу гепатита Е. Среди животных антитела к вирусу гепатита Е были обнаружены у 71 из 665 свиней, что составило 10,7%. Из обследованных 43 свиноводческих хозяйств Могилёвской (21) и Минской (22) областей в 30 хозяйствах обнаружено наличие у свиней антител (70%). На основании этого доказана циркуляция вируса гепатита Е среди животных в Республике Беларусь. = Introduction. Interest in the problem of viral hepatitis E (VGE) has grown in the past decade. In studies conducted in various countries, Hepatitis E virus was detected in animals (wild boars, pigs, birds, wild rats, etc.), and the role of hepatitis E in the occurrence of acute hepatitis E in humans has been demonstrated. Animals support the circulation of the hepatitis E virus in nature, i.e. hepatitis E is a zooanthroponotic infection. In countries where VHE has been identified and serological studies have been conducted among pigs, it has been shown that most pigs over the age of 3-4 months are carriers of anti-HBV. The goal of the work was to conduct studies to determine the presence of hepatitis E virus in swine in the Republic of Belarus. Materials and methods. To determine the serological markers of infection with the hepatitis E virus, an enzyme immunoassay method was used to determine the anti-VGE-IgG, M using the Vector-Best Cytogenesis-E IgG and IgM test system, Novosibirsk. A method for detecting IgG using a solution of Staphylococcus aureus protein conjugated with horseradish peroxidase was tested. The sera of pigs from livestock farms and the private sector of various regions of Belarus (n = 625) were tested for antibodies to hepatitis E. Results of research and discussion. Among the animals, antibodies to the hepatitis E virus were detected in 71 of 665 pigs, which was 10.7%. In 30 of 43 surveyed pig-breeding farms in Mogilev (21) and Minsk (22) regions the presence of antibodies to the hepatitis E virus was detected in 70% of pigs. Conclusions and prospects for further research. Based on this, the circulation of the hepatitis E virus among animals in the Republic of Belarus has been proved, its approximate scales have been determined.
