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.
