The nucleotide sequence of the cytopathic Osloss isolate of bovine viral diarrhoea virus (BVDV) was deduced from overlapping cDNA clones and from PCR products. The Osloss genome is an RNA molecule of positive polarity containing 12480 nucleotides and having the capacity to code for a polyprotein of 3975 amino acids. The presence of the previously described internal stop codon in this viral sequence was disproved after direct sequencing of the appropriate PCR-amplified fragment. Except for the previously reported insertion of a sequence coding for a ubiquitin-like protein, the viral genome shares great similarity with those of three other strains of the pestivirus genus. Computer-assisted sequence analyses and comparisons of known pestiviral genomic sequences led us to identify selected PCR primers in the 5' untranslated region. These primers were used successfully to amplify 18 distinct pestivirus isolates and potential DNA probes were noted from the deduced sequences. The possible use of a well conserved 26 base fragment as a diagnostic probe was confirmed in hybridization experiments. The 5' untranslated region was further studied and compared with those of other members of the Flaviviridae family, which includes the flaviviruses and the hepatitis C virus group. These sequence analyses support the possibility of discrimination amongst the closely related ruminant pestiviruses, border disease virus and BVDV. [less ▲]

We sequenced cDNAs, amplified by the polymerase chain reaction (PCR), which correspond to the carboxy-terminal portion of the 54-kDa protein of various cytopathic (cp) or noncytopathic (ncp) pestiviral strains. Except for the previously described insertions in two cp strains of the bovine viral diarrhea virus (BVDV), we did not find comparable insertions in this gene in eight pestiviral strains. The predicted amino acid sequences of this 54-kDa protein portion contain a conserved cysteine-rich stretch remarkably similar to a "zinc finger-type" binding domain found in many gene-regulatory proteins. Thus, this protein may be involved in the binding to viral RNA. [less ▲]

The genomic RNA from Bovine Viral Diarrhea Virus (BVD) was cloned in E. coli. The complete sequence has been obtained and the genomic organization has been deduced. Some of the BVD specific cDNA have been expressed in bacteria, eucaryotic cells and in vitro. We suggest that BVDV belongs to a new family different from Togaviridae and Flaviviridae. [less ▲]

Bovine viral diarrhea virus (BVDV) genomic RNA was identified as a 12.5-kb single-stranded RNA molecule in both infected bovine embryonic kidney cells (BEK-1) and partially purified virions. BVD virion RNA was partially purified and used as a template for cDNA synthesis. BVDV-specific cDNA sequences were molecularly cloned and shown to hybridize to infected cell RNA but not to uninfected cell RNA or DNA. A single RNA species of 12.5 kb, representing the viral RNA genome, was detected in infected cells. A preliminary map of the BVDV specific cDNA clones was constructed and five major, nonoverlapping families were observed, accounting for approximately one-half of the viral genome. [less ▲]
