Evidence of association between the novel putative border disease virus genotype 8 (BDV-8) and fatal disease in an Alpine chamois ( Rupicapra rupicapra) is reported. Diagnostically, we also demonstrated, as already previously reported, the failure of BDV-specific primers (PDB1 and PDB2) to detect BDV-8. [ABSTRACT FROM AUTHOR]

Border disease virus (BDV) is a (+) single-stranded RNA pestivirus affecting mainly sheep and goats worldwide. Genetic typing of BDV has led to the identification of at least seven major genotypes. This study reports the detection of a BDV strain from a goat in northwestern Italy during routine investigations. Sequence analysis revealed mutations in the 5'-UTR of the virus with implications for BDV molecular diagnostics. Moreover, subsequent phylogenetic analysis based on the combined 5'-UTR and Npro/partial C genes, showed divergence from known BDV genotypes, revealing the detection of a novel pestivirus group, for which we propose the name BDV genotype 8.
