“…In a large-scale study of alphaherpesviruses (BoHV-1 and CvHV-1) in free-living ruminants in Poland, seroprevalence ranged from 0% to 100% in different areas [12]. Due to the small number of analyzed samples, our results do not allow us to determine the general seropositivity In addition, our study has confirmed the results of the study by Shuliak et al [35], who demonstrated the presence of infectious bovine rhinotracheitis virus type 1 circulation in wild artiodactyls in Russia. Data from European scientists also validated the fact that BoHV-1 herpesvirus spread among wild artiodactyls in the countries of Eastern Europe, especially Poland, where the virus was noted in fallow deer, red deer, and, to a lesser extent, roe deer [12].…”

Background and Aim: Some pathogens that cause infections in cattle are found in wild artiodactyls. Their prevalence, possible impact on the population of free-living animals, and the spread of infectious pathology in livestock have yet to be studied. We investigated the occurrence of bovine herpesviruses (BoHV-1, BoHV-4, and BoHV-6) among wild moose and roe deer in 8 areas of the Moscow region in the Russian Federation. Materials and Methods: One hundred and one tissue samples and nasal swabs of 24 moose and seven roe deer were studied using a real-time polymerase chain reaction (PCR) for BoHV-1 DNA and conventional PCR for BoHV-4 and BoHV-6 DNA. A virus neutralization test (VNT) was used to detect antibodies to BoHV-1 in 19 serum samples. The final antibody titer was calculated with the Spearman-Kärber method. Results: BoHV-4 and BoHV-6 DNA were not detected in all studied samples of 31 animals. BoHV-1 DNA was detected using a real-time PCR in nasal swabs from 2 adult roe deer. For BoHV-1, only 9/19 tested serum samples reacted positive in VNT with the titer range from 0.67 ± 0.19 to 3.75 ± 0.10 log2. Antibodies were detected in all age groups, more often in fawns under 1-year-old. The seropositivity of females was higher than in males. Conclusion: Wild ungulates can potentially represent a reservoir of new pathogenic livestock viruses. To study the prevalence and genetic diversity of wild ungulate herpesviruses, detailed molecular studies of the cervid herpesvirus 1, cervid herpesvirus 2, and elk herpesvirus 1 are necessary.

Introduction. Pestiviruses and viruses of the Herpesviridae family are widely distributed among different species of ungulates, but the main information about these pathogens is related to their effect on farm animals. Data on detection of bovine viral diarrhea virus (BVDV) and bovine herpes virus (BoHV) in wild ungulates reported from different countries in recent years raises the question of the role of wild animals in the epidemiology of cattle diseases. Aim of work. To study the prevalence of herpesviruses and pestiviruses in the population of wild artiodactyls of the Moscow region. Materials and methods. Samples of parenchymal organs and mucosal swabs from 124 wild deer (moose and roe deer) shot during hunting seasons 20192022 in Moscow Region were examined by PCR, virological and serological methods for the presence of genetic material and antibodies to bovine infectious rhinotracheitis and viral diarrhea. Results. BVDV RNA was found in a sample from one moose, BoHV DNA was detected in samples from three roe deer and two moose shot in the Moscow region. Seropositive animals were of different sex and age, the total BoHVs and BVDV seroprevalence rates in wild artiodactyls were 46 and 29%, respectively. Conclusion. Wild ruminant artiodactyls of the Moscow Region can be a natural reservoir of BoHV-1, and this must be taken into account when planning and organizing measures to control the infectious bovine rhinotracheitis. Cases of BVDV infection in wild artiodactyls are less common, so more research is needed to definitively establish their role in the epidemiology of this disease in cattle.
