“…Similar results, i.e. higher rate of BVDV seroprevalence in pigs on mixed farms, was also reported by Deng et al (19), and Tao et al (38). At that time, the presence of seroreagents was found in all provinces in which the samples were collected (29).…”

“…From these five subtypes, one was found to be a novel subgenotype BVDV-1q, not detected previously in China (4). Another group of Chinese researchers indicated that BVDV seroprevalence in pigs in Shanghai in 2007 and 2008 was 35.9% and 64.1% respectively (38). These findings strongly suggest an increasing rate of BVDV infection in pigs in the region, and indicate that BVDV-1 is the predominant genotype of BVDV strains in China (38).…”

“…A high homology rate between CSF and BVD viruses, interspecies crossing, and infection of pigs with BVDV could create a serious diagnostic problem (25,36,37,43). Cattle is considered as the main reservoir and source of BVDV for pigs (7,8,10,15,16,19,38,41). Lenihan and Collery (15) found that 27.8% BVDV antibody positive sows had contact with cattle, while 3.6% seropositive sows were without contact, and 4.5% of five-six months old pigs have had little or no contact with cattle.…”

In total, 14 608 pig sera, collected between 2008 and 2011, were tested with ELISA using antibodies specific for bovine viral diarrhoea virus (BVDV). All doubtful and positive samples were retested by virus neutralisation test (neutralising peroxidase-linked assay). The BVDV seroreagents were detected in 11 (68.75%) out of 16 provinces, the seroprevalence varied from 0.1% to 1.04% (average 0.31%). The obtained results indicate that the prevalence of BVDV infection in pig population in Poland is low.

“…The possibility of BVDV persisting in other domesticated or wild ruminants must also be considered when assessing the risk of transmission and reintroduction. BVDV has been isolated from both sheep (Paton et al 1995) and pigs (Tao et al 2013), which can be reared alongside cattle on mixed farms. The analysis of thirteen BVDV isolates collected from cattle and sheep from a number of Swedish farms suggested that isolates were herd-specific rather than species-specific, indicating that BVDV has the potential to be transmitted between the two species (Paton et al 1995).…”

The genotype and subgenotype was established for 325 field viruses and one commercial vaccine viral strain based on the analysis of at least one genomic region. BVDV-1a was the prominent subgenotype (n=317) with BVDV-1b (n=6), BVDV-1d (n=1) and BVDV-1e (n=1) also observed. A number of nucleotide sequence alignments and phylogenetic trees were constructed to represent the relationship between Irish field viruses and reference strains representative of all known BVDV genotypes and subgenotypes. Evidence of both herd specific clustering and circulation of multiple strains within herds was observed; however no evidence of county specific clustering was observed. A number of completely conserved nucleotide regions were observed and the 5'UTR was found to be more conserved than the N pro fragment analysed. The results of this study provide a detailed and comprehensive insight into the genetic diversity of BVDV in circulation within Irish cattle herds and will act as a baseline reference for future BVDV genotyping studies.

The SD0803 strain of the bovine viral diarrhea virus (BVDV) was isolated from a piglet in China in 2008 and has been classified as a novel subgenotype of BVDV-1. To describe the molecular features of this novel subgenotype, we sequenced and characterized the complete genome of the SD0803 virus. The genome is 12,271 bp in length and contains 5' and 3' untranslated regions (UTRs) that flank an open reading frame (ORF) encoding a 3,898-amino-acid polypeptide. The full-length genome of the SD0803 strain shares 78.8% to 83.3% identity with those of other BVDV-1 strains, 70.0% to 70.7% identity with those of BVDV-2 strains, and less than 67.6% identity with those of other pestiviruses. The highest level of shared identity was 83.3% between the complete SD0803 genome and that of the ZM-95 strain of BVDV-1. Phylogenetic analysis of the 5' UTR and the coding sequence for the N-terminal protease fragment of the SD0803 polyprotein indicated that the SD0803 virus is a member of the novel subgenotype BVDV-1q, isolates of which have been identified recently in dairy cattle and camels in China.
