“…Decline in the percentage of SBV‐seropositive yearlings from 2013 to 2014 suggests lower exposure of those animals to the virus indicating a decrease in SBV circulation. Similar dynamics of SBV infections was also observed in wild ruminants in Germany with the decrease of SBV‐seropositive animals in 2013/2014 hunting season (EFSA, ; Mouchantat et al., ). Only three of 12 (25%) European bison born in 2014 had SBV antibodies; these results are likely to be due to passive immunity rather than an acute infection, especially considering the high seroprevalence rates in their mothers.…”

Bison bonasus is an indigenous species of Central and Eastern Europe with the largest wild population inhabiting Białowieża Primeval Forest; however, free-living and captive European bison are reared in many countries around the world. Despite that the European bison was rescued from the extinction after the First World War, it remains as endangered species. Changing environment as well as human activity may have contributed to the observed increase of the risk of the emergence and re-emergence of pathogens. The aim of the survey was to establish the distribution of four pathogens transmitted by arthropods including three arboviruses [Bluetongue disease virus (BTV), Epizootic haemorrhagic disease virus (EHDV) and Schmallenberg virus (SBV)] and a bacteria (Francisella tularensis) in the main populations of European bison in Poland. A total of 251 European bison originating from eight main populations were included in the study and sampled between February 2011 and December 2014. Serum samples originated from chemically immobilized, eliminated or dead by natural causes animals. Additionally, 65 cervids from Białowieża Forest were tested to compare the seroprevalences of other ruminants inhabiting the same environment. The antibodies to SBV and BTV were found in 76.1% and 24.7% of European bison, respectively. In autumn 2012, simultaneous emergence of SBV and BTV in European bison was observed; however, while SBV has spread in all populations scattered around the country, BTV infections were observed only in the north-eastern part of Poland, where BTV cases have been previously reported in domestic ruminants. European bison age was found to be the only significant risk factor for SBV and BTV seroprevalences; however, this association was connected to the animal size, rather than to the length of exposure. None of the animals tested positive for antibodies against EHDV or F. tularensis. SBV exposure rate of cervids was much lower (35.4%) than in European bison, while BTV seroprevalence was comparable in both groups.

“…However, not so much is known about other prevalent viral diseases of swine such as porcine circovirus type 2 (PCV-2), porcine reproductive and respiratory syndrome virus (PRRSV), influenza A virus (IAV), porcine parvovirus (PPV) (Gonzáles-Barrio et al, 2015;Sliz et al, 2015;Touloudi et al, 2015). Unexpectedly, specific antibodies against Schmallenberg virus (SBV) were detected in wild boars (Mouchantat et al, 2015). Despite of the fact that enteric viruses are significant pathogens of domestic pigs, they have been studied only sporadically in wild boar.…”

Population of wild boar is increasing in the whole Europe, the animals migrate close to human habitats which greatly increases the possibility of natural transmission between domestic animals or humans and wild boars. The aim of the study was to estimate in population of free-living wild boar in the Czech Republic the prevalence of enteric viral pathogens, namely rotavirus groups A and C (RVA and RVC), porcine reproductive and respiratory syndrome virus (PRRSV), and members of family Coronaviridae (transmissible gastroenteritis virus - TGEV, porcine epidemic diarrhea virus - PEDV, porcine respiratory coronavirus - PRCV, and porcine hemagglutination encephalomyelitis virus - PHEV) and Picornaviridae,(teschovirus A - PTV, sapelovirus A - PSV, and enterovirus G - EV-G). In our study, stool samples from 203 wild boars culled during hunting season 2014-2015 (from October to January) were examined by RT-PCR. RVA was detected in 2.5% of tested samples. Nucleotide analysis of VP7, VP4, and VP6 genes revealed that four RVA strains belong to G4P[25]I1, G4P[6]I5, G11P[13]I5, and G5P[13]I5 genotypes and phylogenetic analysis suggested close relation to porcine and human RVAs. The prevalence of RVC in wild boar population reached 12.8%, PTV was detected in 20.2%, PSV in 8.9%, and EV-G in 2.5% of samples. During our study no PRRSV or coronaviruses were detected. Our study provides the first evidence of RVC prevalence in wild boars and indicates that wild boars might contribute to the genetic variability of RVA and also serve as an important reservoir of other enteric viruses.

“…The epidemics swept through the European continent in 2011-2012 and reemerged in 2014 [11,12]. The presence of viral genome has been confirmed in various ruminants (cattle, sheep, goat, elk, and wildebeest) and serology tests indicated that a number of additional species (bison, deer, mouflon, and chamois) are also susceptible to SBV infection [13][14][15][16][17]. In adult hosts, SBV infection typically results in subclinical infection or moderate clinical signs, such as fever, decreased milk production, or diarrhoea.…”

Since its emergence near the German-Dutch border in 2011, Schmallenberg virus (SBV) has been identified in many European countries. In this study, we determined the complete coding sequence of seven Hungarian SBV genomes to expand our knowledge about the genetic diversity of circulating field strains. The samples originated from the first case, an aborted cattle fetus without malformation collected in 2012, and from the blood samples of six adult cattle in 2014. The Hungarian SBV sequences shared ≥99.3% nucleotide (nt) and ≥97.8% amino acid (aa) identity with each other, and ≥98.9 nt and ≥96.7% aa identity with reference strains. Although phylogenetic analyses showed low resolution in general, the M sequences of cattle and sheep origin SBV strains seemed to cluster on different branches. Both common and unique mutation sites were observed in different groups of sequences that might help understanding the evolution of emerging SBV strains.
