Seroprevalence of Antibodies to Main Porcine Infectious Pathogens in Wild Boars in Some Regions of Russia

Results of testing 107 serum samples from wild boars (Sus scrofa L., 1758) for thepresence of antibodies to six economically significant porcine infectious disease agents (porcinereproductive and respiratory syndrome (PRRS) virus, porcine parvovirus (PPV), swine influenza virus(SIV) of H1N1 and H3N2 subtypes, Aujeszky’s disease virus (ADV), porcine transmissiblegastroenteritis virus (TGEV) and Mycoplasma hyopneumoniae) are presented in the paper. Wild boarwere sampled in seven regions of Russia for diagnostic purposes. The obtained results showed thepresence of antibodies to ADV in 32.5% of samples (83/27), to PPV – in 62% of samples (92/57), toMycoplasma hyopneumoniae – in 52% of samples (98/51). All samples were seronegative to PRRSvirus (107/0), TGEV (91/0) and SIV of H1N1 (89/0) and H3N2 (58/0) subtypes. The researchesdemonstrated the extensive circulation of porcine parvovirus, Aujeszky’s disease virus andMycoplasma hyopneumoniae among Wild boar in some regions of Russia

IMMUNOBIOLOGICAL PROPERTIES OF AUJESZKY DISEASE VIRUS STRAINS

It has been shown that in the biological properties of the virus there are differences connected with the pathogenicity for different animals. The accumulation of the Aujeszky disease virus in the organs and tissues and extraction has been connected with pathogenicity and tissue tropism. The epizootic strains of the virus are heterogeneous according to the antigenic characteristics and structure of the genome. The virus indication scheme in the veterinary inspection objects has been developed.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
