“…Phylogenetic analyses based on the whole genome, 5 ′ UTR, and N pro sequences showed that strain was closely related to previously characterized BVDV-1i (JQ920104.1, JQ920215.1, and FJ493484.1) from the UK (90.5% highest nt identity at 5 ′ UTR) and Uruguay (KT833795.1) (90.6 high identity at N pro ). Mósena et al (2017aMósena et al ( , 2017b performed the full genomic sequencing and antigenic characterization of two previously described Brazilian HoBiPeV isolates (Bianchi et al, 2011;Weber et al, 2016aWeber et al, , 2016b. According to the authors, the presented data provided evidence that HoBiPeVs are members of the genus Pestivirus and should be formally recognized as a novel species.…”

“…Recently, this group of viruses has been recognized as a new pestivirus species, named Pestivirus H (ICTV, 2017) (proposed abbreviation, HoBiPeV). The origin, distribution, and relevance of HoBiPeV are still unclear, yet a number of studies demonstrated that these viruses are endemic in Brazil (Cortez et al, 2006;Weber et al, 2016aWeber et al, , 2016bSilveira et al, 2017Silveira et al, , 2018Monteiro et al, 2018aMonteiro et al, , 2018b.…”

“…Amplification of the 5 ′ UTR followed by phylogenetic analysis revealed that all five calves were infected with a BVDV-2b strain (Santos et al, 2011). A BVDV-2b isolate was also detected in lung samples of a wild boar collected in a commercial slaughterhouse in RS in 2012 (Weber et al, 2016a(Weber et al, , 2016b. Alves et al (2016) detected a BVDV-1a genome in the sera of cattle during an outbreak of vesicular disease by pseudocowpox virus in Pará (PA), northern Brazil.…”

The pestiviruses bovine viral diarrhea virus 1 (BVDV-1), 2 (BVDV-2), and HoBi-like (HoBiPeV) are endemic among Brazilian cattle, the world's largest commercial bovine herd. In the last two decades (1998–2018) over 300 bovine pestiviruses have been partially or fully sequenced in Brazil, including viruses from different regions, different epidemiological backgrounds, and associated with diverse clinical presentations. Phylogenetic analysis of these viruses demonstrated a predominance of BVDV-1 (54.4%), with subgenotypes −1a (33.9% of total) and −1b (16.3%) being more frequent and subgenotypes −1d, −1e, and −1i at very low frequencies. The overall BVDV-2 frequency was 25.7% but it varied largely by region, reaching up to 48% in Southern states. BVDV-2b was the predominant subgenotype (84.8% of BVDV-2), followed by BVDV-2a (8.86%). HoBiPeV accounted for 19.9% (61/307) of the genotyped viruses and were detected at high frequency in cattle from Northeastern states. These findings demonstrate a unique mix of pestivirus species and subgenotypes, unlike that seen in Europe or North America. The design of effective diagnostic tools, vaccines, and control programs for limiting bovine pestivirus infections in Brazil must take into consideration this unique mix of viruses. This article provides a critical review of two decades of genetic identification of pestiviruses in Brazil.

“…Infection caused by BVDV in pigs has been reported in China [ 9 ], the Netherlands [ 10 ], Brazil [ 11 , 12 , 13 ], Austria [ 14 ], Germany [ 15 ], Norway [ 16 ], Ireland [ 17 ], Denmark [ 18 ] and others. These data were found not only in domestic pigs but also in wild boars [ 19 ], which raise concerns about risk factors involved in BVDV infection, the clinical form of the disease, and the existence of accurate diagnostic tests. In Brazil, BVDV-1d was frequently reported in cattle [ 20 ].…”

“…Researchers have adapted numerous variations of PCR methods for the detection of infectious agents, using DNA templates as well as RNA templates after an RT step [ 42 ], which has enabled more accurate, sensible and specific diagnostics. Direct sequencing of the RT-PCR product for fragments of 5′UTR and N-terminal autoprotease (N pro ) may also provide accurate differential diagnosis [ 19 ].…”

Bovine viral diarrhea virus (BVDV) is an important pathogen belonging to the Pestivirus genus, Flaviviridae family, which comprises viral species that causes an economic impact in animal production. Cattle are the natural host of BVDV and the main source of infection for pigs and other animal species. Due to its antigenic and genetic similarity with other important pestiviruses such as Classical Swine Fever Virus (CSFV), several studies have been conducted to elucidate the real role of this virus in piglets, sows, and boars, not only in the field but also in experimental infections, which will be discussed in this paper. Although BVDV does not pose a threat to pigs as it does to ruminants, the occurrence of clinical signs is variable and may depend on several factors. Therefore, this study presents a survey of data on BVDV infection in pigs, comparing information on prevalence in different countries and the results of experimental infections to understand this type of infection in pigs better.

First molecular evidence of border disease virus in wild boars in Turkey

Molecular studies on viral diseases in wildlife are limited in Turkey. Pestiviruses infect domestic animals such as pig, cattle, sheep, goats and many other wild ungulates. Cross-species transmission of pestiviruses between wildlife and domestic livestock is a subject of recent concern where wild ungulates are in close contact with domestic ruminants. The International Committee on Virus Taxonomy (ICTV) has named the genus Pestivirus , which belongs to the Flaviviridae family, using the format Pestivirus A, Pestivirus B, Pestivirus C, and so on. Pestivirus A-D replaces Bovine viral diarrhea virus-1 (BVDV-1), Bovine viral diarrhea virus-2 (BVDV-2), Classical swine fever virus (CSFV) and Border disease virus (BDV) respectively. During the 2013–2014 hunting season, a total of 40 samples were collected from wild boars ( Sus scrofa ferus ) in the area of Western Mediterranean Turkey. In the samples, nucleic acids were investigated for pestivirus, Aujeszky’s disease virus, Borna disease virus, coronavirus, mastadenovirus and rotavirus. RT-PCR was performed using primary sets to detect specific partial gene region specific to each virus. Sequence analysis was performed on a positive sample. Phylogenetic analysis revealed that the positive sample, TR/Burdur/13/Boar3, belonged to BDV genotype 1 ( Pestivirus D). The first molecular findings of BDV in wild boars in Turkey are reported in this study. This study highlights the importance of further research into diseases that might be transmitted from wild boars to ruminants in Turkey.
