Non-Bovine Species and the Risk to Effective Control of Bovine Viral Diarrhoea (BVD) in Cattle. Pathogens 2021; 10:pathogens10101263.

Abstract
Bovine viral diarrhoea virus (BVDV) is an economically important and highly prevalent virus of domestic cattle. Infections with BVDV may lead to both, reproductive and immunological effects that can result in widespread calf losses and increased susceptibility to diseases, such as mastitis and respiratory disease. While BVDV is generally considered to be host specific, it and other Pestivirus species, such as Border disease virus (BDV) in sheep, have been shown to be infecting species other than those from which they were originally isolated from. Recently BVDV was placed on the OIE’s list of notifiable disease and control and eradication programmes for BVDV have been developed throughout much of Europe, the United States, and the United Kingdom. While some countries, including Sweden and Ireland have successfully implemented eradication programmes, other countries such as New Zealand and Australia are still in the early stages of BVDV control. Despite effective control methods, incursions of BVDV into previously cleared herds still occur. While the cause of these incursions is often due to lapses in control methods, the ability of ruminant pestiviruses to infect species other than cattle poses the question as to whether non-bovine species could be impeding the success of BVDV eradication and control. As such, the aim of this review is to make mention of what is known about the cross-species transmission of BVDV, BDV and other pestiviruses between cattle and non-bovine ungulate species and draw conclusions as to the risk non-bovine species pose to the successful control and eradication of BVDV from cattle.

Front Vet Sci 2021; 8:702730.

Abstract
Bovine viral diarrhoea virus (BVDV) and related ruminant pestiviruses occur worldwide and cause considerable economic losses in livestock and severely impair animal welfare. Switzerland started a national mandatory control programme in 2008 aiming to eradicate BVD from the Swiss cattle population. The peculiar biology of pestiviruses with the birth of persistently infected (PI) animals upon in utero infection in addition to transient infection of naïve animals requires vertical and horizontal transmission to be taken into account. Initially, every animal was tested for PI within the first year, followed by testing for the presence of virus in all newborn calves for the next four years. Prevalence of calves being born PI thus diminished substantially from around 1.4% to <0.02%, which enabled broad testing for the virus to be abandoned and switching to economically more favourable serological surveillance with vaccination being prohibited. By the end of 2020, more than 99.5% of all cattle farms in Switzerland were free of BVDV but eliminating the last remaining PI animals turned out to be a tougher nut to crack. In this review, we describe the Swiss BVD eradication scheme and the hurdles that were encountered and still remain during the implementation of the programme. The main challenge is to rapidly identify the source of infection in case of a positive result during antibody surveillance, and to efficiently protect the cattle population from re-infection, particularly in light of the endemic presence of the related pestivirus border disease virus (BDV) in sheep. As a consequence of these measures, complete eradication will (hopefully) soon be achieved, and the final step will then be the continuous documentation of freedom of disease.

Abstract
Border disease virus (BDV) belongs to the genus Pestivirus of the family Flaviviridae. Interspecies transmission of BDV between sheep, cattle, and pigs occurs regularly, sometimes making diagnosis a challenge. BDV can yield substantial economic losses, including prenatal and postnatal infections in lambs, which are the primary source of infection and maintenance of the virus in the population. Since BDV is antigenically and genetically related to bovine viral diarrhea virus (BVDV), it might pose a significant risk to cattle, influencing BVDV eradication campaigns. Similarly, the presence of BDV in swine herds due to pestivirus spillover between small ruminants and pigs might cause uncertainty in classical swine fever virus (CSFV) diagnostics. Therefore, knowledge of BDV epidemiology in different geographical regions will help prevent its spread and optimize control measures. Previous epidemiological studies have shown that various BDV genotypes are predominant in different countries. This review provides an overview of the spread of BDV world-wide in different host species.

Abstract
Melophagus ovinus (sheep ked) is a blood-sucking ectoparasite that is parasitic primarily on sheep. It is widely distributed in different geographical regions worldwide. In China, it has been mainly found in Xinjiang, Gansu, and Tibet in recent years. In addition to causing direct damage to the animal hosts, M. ovinus also carries pathogens and serves as a vector for disease transmission. Border disease virus (BDV) is a positive-sense, single-stranded RNA pestivirus that mainly infects and causes border disease (BD) in sheep and goats worldwide. Since 2012, this disease has been reported in 4 provinces in China. In the present study, we investigated the presence of BDV in M. ovinus from Xinjiang and Gansu. Frozen M. ovinus collected during 2017 and 2018 from Xinjiang and Gansu and preserved in our laboratory were studied. First, total RNA of M. ovinus was extracted, followed by reverse transcription, PCR (RT-PCR) amplification of the 5′-UTR of BDV, and sequencing of the amplified products. Finally, the sequencing results were analyzed using DNAStar, MEGA 5.0 molecular biology software, and the BLAST online platform. The results from RT-PCR and sequencing analyses showed that among the samples included in the study, only the M. ovinus collected from Qinghe County in Alta, Xinjiang in 2018 tested positive for BDV. BLAST analysis showed that the viral strain with the most similar nucleotide identity to the sequence of the China/BDV/2018 fragment was the goat-derived BDV strain AH12-02 collected in Anhui, China, in 2012. A phylogenetic-tree analysis showed the strain to exhibit a BDV-3 genotype. This is the first report globally on BDV detected in M. ovinus and is also the first report of BDV discovered in Xinjiang, China. This study reconfirms the presence of BDV in China.

Abstract
We examined acute phase protein (APP) concentrations in viral infections of dairy ruminants and assessed the potential role of characteristic patterns of APP changes in auxiliary diagnosing viral diseases. All viruses reviewed are common causes of farm animal diseases. APPs are among the first agents of immunity, and their concentrations could be diagnostically relevant. In the most common ruminant viral diseases, elevated serum amyloid A (SAA) and haptoglobin (Hp) levels in blood serum have been observed. However, since these proteins are the main APPs in many viral infections, it is impossible to use their levels for diagnosing particular infections. Decreased Cp and albumin expression could help differentiate the bluetongue virus infection from other diseases. Lastly, analysis of SAA levels in blood serum and milk could be helpful in diagnosing small ruminant lentivirus infection. While promising, APP levels can only be considered as an auxiliary tool in diagnosing viral diseases in ruminants.

Abstract
ABSTRACT The present study investigated the seroprevalance of Visna Maedi Virus (VMV) and Border Disease Virus (BDV) infections in sheeps in regions in and around Van province, Turkey. Sample materials were taken from 360 sheep sent to slaughterhouses around Van. All serum samples were examined using ELISA for antibodies for Visna Maedi (VMV) and Border Disease (BDV) viruses. Of these, 38 (10.5%) tested positive for Visna Maedi virus antibodies and 163 (45.2%) for Border Disease virus antibodies. Varying numbers of samples were positive for both virus antibodies across the towns of Erciş, Çaldıran, Erçek and Başkale in Van, Ağrı and Hakkari provinces. Both infections should be eliminated by informing veterinarians and animal owners, identifying and eliminating persistently infected animals from flocks, and conducting appropriate eradication measures. Economic support should be provided for this.

Abstract
Border disease has been assessed according to the criteria of the Animal Health Law (AHL), in particular criteria of Article 7 on disease profile and impacts, Article 5 on the eligibility of Border disease to be listed, Article 9 for the categorisation of Border disease according to disease prevention and control rules as in Annex IV and Article 8 on the list of animal species concerned by Border disease. The assessment has been performed following a methodology composed of information collection and compilation, expert judgement on each criterion at individual and, if no consensus was reached before, also at collective level. The output is composed of the categorical answer, and for the questions where no consensus was reached, the different supporting views are reported. Details on the methodology used for this assessment are explained in a separate opinion. According to the assessment performed, Border disease can be considered eligible to be listed for Union intervention as laid down in Article 5(3) of the AHL. The disease would comply with the criteria as in Sections 3, 4 and 5 of Annex IV of the AHL, for the application of the disease prevention and control rules referred to in points (c), (d) and (e) of Article 9(1). The animal species to be listed for Border disease according to Article 8(3) criteria are mainly sheep and other species of the family Bovidae as susceptible and reservoirs.

Abstract
The genus Pestivirus within Flaviviridae is comprised of four recognized species, namely, bovine viral diarrhoea virus 1 (BVDV-1), bovine viral diarrhoea virus 2 (BVDV-2), border disease virus (BDV) and classical swine fever virus (CSFV). BDV, while primarily infecting sheep and goats, has also been reported in cattle and wild animals. Infections of sheep and goats result in economic loss due to abortions and the birth of persistently infected animals that have poor production and reduced life expectancy. In this study, we report the detection of BDV in cattle serum collected as part of pestivirus surveillance programme from six regions of Mexico, where a 67.1% of BVDV seroprevalence was calculated previously. Phylogenetic analyses based on comparison of the 5'UTR region typed the Mexican strains as BDV-1. Border disease (BD) is listed as an exotic disease in Mexico, and the origin of BDV found in these cattle is unclear. This is the first identification of BDV in Mexican cattle.

Abstract
Bovine viral diarrhoea virus (BVDV) and Border disease virus (BDV) were investigated at the wildlife-livestock interface in the distribution area of chamois in the Cantabrian Mountains, North-Western Spain. From 2010 to 2014, sera from sympatric wild (n=167) and domestic (n=272) ruminants were analysed for pestivirus antibodies by cELISA, virus neutralisation test (VNT) and for the presence of pestiviral RNA using a reverse transcription (RT)-PCR. Results showed a higher seroprevalence in cattle (59.4 per cent, 13/13 of herds) than in domestic small ruminants (5.9 per cent sheep, 2/8 of flocks; 0 per cent goats of 4 flocks) and wildlife (10.8 per cent in red deer, 0 per cent in roe deer and 0 per cent in Cantabrian chamois). High VNT titres were detected in two cattle herds, suggesting the circulation of BVDV-1 and BVDV-2 strains. BVDV-1 RNA was detected in one cattle calf by RT-PCR and sequencing. Conversely to other similar grazing systems, sheep flocks did not play a relevant role in the pestivirus epidemiology in this region. Pestivirus infections in wild ruminants were sporadic and most probably dependent on a domestic source.

Abstract
In alpine pasture, interspecies transmission has recently been incriminated in the epidemiology of pestivirus infection. The aim of this study was to investigate pestivirus infections in wild and domestic ruminants sharing pastures in the French Southern Alps. Animal sera were screened for pestivirus antibodies against the pestivirus NS3 protein by a commercial blocking enzyme linked immunosorbent assay (ELISA). All 38 domestic herds tested were positive for pestivirus-specific antibodies. Individual sero-prevalence reached 76.5% (95% confidence interval [95% CI]: [74.2-78.8%]) of the 1383 sheep tested. For wild ruminants, 38.7% (95% CI: [33.8-43.9%]) of the 369 chamois tested, 28.7% (95% CI: [17.4-38.1%]) of the 72 roe deer, and 22.2% (95% CI: [6.5-37.9%]) of the 27 mouflons were seropositive. Virus screening was carried out on spleen samples from hunted wild animals (n=160) and from 15 domestic ruminants (clinically suspected to be persistently infected animals), by a conventional reverse transcription-polymerase chain reaction (RT-PCR). Three pestivirus strains were isolated from the sheep samples positive by RT-PCR. The viruses were classified in the BDV-3, BDV-Tunisian and BDV-6 genotypes. For the first time, one strain (RUPI-05 strain) was isolated from an alpine chamois and clustered in the BDV-6 genotype, showing in the 5'-UTR region 92% of identity with the ovine isolate from the same area. Thus, an active circulation of pestiviruses was demonstrated in both wild and domestic ungulates from the French Southern Alps. The results suggest that interspecies transmission between sheep and chamois probably occur.

Pestivirus infection in sheep and goats in West Austria. Vet J 2009; 186:342-6.

Abstract
Blood samples from 3112 sheep (185 flocks) and 1196 goats (163 flocks) from the Western region of Austria were tested for pestivirus-specific RNA. In this area, communal Alpine pasturing of sheep, cattle and goats is an important part of farming. The prevalence of sheep persistently-infected (PI) with pestivirus was 0.32% (10 animals) and the PI animals originated from five flocks (2.7% of those investigated). In goats, only one PI animal (0.08%) was detected. Sequence analysis of the 5'-end untranslated region (UTR) revealed that the strains of Border disease virus (BDV) detected were closely related to genotype 3 but the PI animals did not show any clinical signs of Border disease. The goat was PI with bovine viral diarrhoea virus-1 (BVDV-1). On one farm a high abortion rate among sheep had been observed 1year before the study was carried out but the other farms did not show any evidence of reproductive failures. Pestiviruses are endemic in small ruminants in some Alpine regions of Austria and PI healthy animals as described here have a key epidemiological role. A successful BVDV eradication programme in Austria will create highly pestivirus-susceptible cattle populations. Sheep and goats present a high risk for the reintroduction of pestiviruses to cattle herds because they are less likely to be considered to be PI. The results underline the need for the immediate consideration of small ruminants in eradication programmes.

Antigenic and genetic characterisation of border disease viruses isolated from UK cattle. Vet Microbiol 2009; 141:208-15.

Abstract
Available empirical data on the natural occurrence of ruminant pestiviruses has shown that in cattle, bovine viral diarrhoea virus (BVDV) is nearly exclusively found, whereas both border disease virus (BDV) and BVDV can be isolated from sheep. During routine genetic typing of pestivirus RNA from UK cattle diagnosed as BVDV positive between 2006 and 2008, five samples that were classified as BDV positive yielded positive virus isolates in cell cultures. The samples originated from animals that had shown signs typical for BVD. Phylogenetic analysis of the bovine BDVs showed that two belonged to the BDV-1a group and three to the BDV-1b group, thereby matching the genetic diversity seen for previously described UK ovine BDVs. Antigenic typing with a set of monoclonal antibodies (MABs) showed that all bovine BDVs lacked one or more epitopes conserved among ovine BDV-1 isolates, and that they had gained reactivity with at least one BVDV-1 specific MAB. Serial passaging of two of the virus isolates in ovine cell cultures did not change the epitope expression pattern. These findings suggest that the presumed natural resistance of cattle against infection with BDV no longer holds. A consequence of this is that BVD diagnostic assays should be checked for their ability to also detect BDV, and also highlights the need for monitoring of the BDV status in sheep that may be in contact with cattle in areas with organised BVD control programmes.

Abstract
The genetic diversity of bovine viral diarrhoea virus (BVDV) isolates in infected cattle from Tyrol and Vorarlberg (Austria) was investigated. Blood samples were collected within the compulsory Austrian BVDV control programme during 2005 and 2006. The 5'-untranslated region (5'-UTR) and partially the N-terminal autoprotease (N(pro)) were amplified by one-step reverse transcriptase-polymerase chain reaction (RT-PCR) and the PCR products were subsequently sequenced. Phylogenetic analysis based on 5'-UTR and N(pro) sequences demonstrated that almost all isolates (307/310) were of the BVDV-1 genotype. They were clustered into eight different subtypes, here listed by their frequency of occurrence: BVDV-1h (143), BVDV-1f (79), BVDV-1b (41), BVDV-1d (28), BVDV-1e (6), BVDV-1a (4), BVDV-1g (3) and BVDV1-k (3). Two pestivirus isolates were typed as BVDV-2 and one isolate as BDV closely related to Gifhorn strain (BDV-3). Correlation among isolates could only be observed at the farm level, i.e., within a herd. However, no correlation between the genetic and geographical distances could be observed above the farm level. Because of the wide distribution of certain BVDV-1 subtypes and the low prevalence of herd-specific strains, a determination of tracing routes of infection was not possible. Furthermore, recombination events were not detected.
