“…This genetic difference is also shown in other genes and in phylogenetic networks constructed using partial us8 sequences [16]. This exacerbated difference associated with the high genetic diversity of the group may be related to a rapid dispersion of SuHV-1 since its first recorded case in 1950s [22], and it could possibly be influenced by the fact that Asian pigs possess a more diverse genetic profile than Western pigs [38].…”

“…Pseudorabies eradication programs have restricted the number of outbreaks of the disease to the point of eradicating it from commercial herds of DS in many countries, but it still remains a global concern because of outbreaks in various locations such as Eastern Europe [16]. The prevalence of SuHV-1 in DS in these regions is not the sole problem because the virus persists in herds of wild boar and feral pigs in various parts in the world, with high prevalence rates in certain regions [34].…”

“…These groups have different evolution rates and separate viruses isolated from DS and WS; they also show that viruses isolated in Asia are more genetically diverse than viruses isolated in Europe and America. Phylogenetic analysis using other genes also shows a clear separation between samples isolated in Western and Eastern countries and shows a rapid dispersion of SuHV-1 in China [16]. …”

Objective: The aim of this study was to use partial Ul44 sequences (glycoprotein C) of Suid herpesvirus 1 to examine the evolution and dynamics of the virus in different periods and hosts. Methods: Phylogenetic trees were constructed using the software MrBayes after analysis in the software jModelTest to evaluate the best phylogenetic models. The software SplitsTree 4.0 was used to create phylogenetic networks, and the BEAST program was used to generate data on phylogeography. Replication kinetics and serum neutralization tests were applied to tree strains from different phylogenetic groups. Results:Ul44 sequences derived from domestic swine and wild swine clustered in different clades and had different selective pressures depending on the host. We found no differences in replication kinetics and serum neutralization tests in the strains tested. Data show that the evolution of herpesviruses is complex, and different genetic groups may be evolving at different rates. Ul44 is an important marker for molecular evolution and epidemiology studies, but it is not useful for biological information.

BackgroundAujeszky’s disease is a viral disease of suids caused by Suid Herpesvirus 1. The disease has worldwide distribution with significant economic impact. In Serbia, there is neither an Aujeszky’s disease eradication nor national vaccination programme of domestic pigs.Since clinical symptoms of Aujeszky’s disease are not specific, it is important to establish a link between clinical signs and presence of ADV active infection in wild boars. The aim of this study was to investigate the possibility of active infection within wild boar showing signs of ADV and also to examine relationship between isolates from domestic pigs and wild boar. Having in mind that virus has not been previously isolated from wild boars in Serbia, we report the first isolation of Suid Herpesvirus 1 from this species in Serbia.ResultsTissue and serum samples from 40 wild boars from eastern Serbia were examined for evidence of Aujeszky’s disease (AD). Suid Herpesvirus 1 (SHV1), the cause of AD was isolated on PK15 cell line from three tissue samples, inducing cytopathic effect (CPE) with syncytia forming, and viral genome was detected by polymerase chain reaction (PCR) in eight samples. Genetic analysis of us4, us9 and ul49.5 partial sequences showed high homology between ADV isolates from wild boars and between isolates from wild boars and domestic animals. Neutralizing antibodies were not detected by virus neutralisation test (VNT) in sera from four out of eight PCR positive wild boars suggesting recent infection in those animals.ConclusionsThis is the first demonstration of Aujeszky’s disease virus (ADV) in the wild boar population in Serbia although seroconversion has been detected previously.
