Goat Anti-BVDV polyclonal antibody for IFA. BVDV is a member of the Pestivirus genus, belonging to the family Flaviviridae. Border Disease Virus (Sheep) and Classical Swine Fever Virus (Pigs) are other members of this genus which also cause significant financial loss to the livestock industry.Pestiviruses are small, spherical, single-stranded, enveloped RNA viruses of 40 to 60 nm in diameter.The genome consists of a single, linear, positive-sense, single-stranded RNA molecule of approximately 12.3 kb. Two BVDV genotypes are recognised, based on the nucleotide sequence of the 5'untranslated (UTR) region; BVDV-1 and BVDV-2. BVDV-1 isolates have been grouped into 16 subtypes (a–p) and BVDV-2 has currently been grouped into 3 subtypes (a–c).
