han sido divididos en 5 especies de acuerdo con sus diferencias genomicas: el Virus de la Peste Porcina Clasica (cepa de referencia Alfort), Enfermedad de la Frontera (BD31), Diarrea Viral Bovina genotipo 1 (NADL), Diarrea Viral Bovina genotipo 2 (890) y un posible virus de Diarrea Viral Bovina genotipo 3 o "HoBi virus" que ha sido recientemente propuesto (Liu et al.
CSF is caused by CSF virus, which is a small, enveloped RNA virus in the genus Pestivirus
of the family Flaviviridae .
Retinal dysplasia maybe associated with maternal infection, e.g., infection with bovine viral diarrhea-mucosal disease (BVD-MD) virus (pestivirus
) later than 76 days but before 150 days of gestation or intrauterine infection with feline panleukopenia virus among others .
Bovine viral diarrhea virus-1 (BVDV-1) and BVDV-2, together with classical swine fever virus and border disease virus (BDV), are currently classified as the genus Pestivirus
and family Flaviviridae .
In a study of 26 commercially available FBS products, all samples contained at least one species of bovine pestivirus
by RT-PCR .

In addition to the flaviviruses (genus Flavivirus), the family includes 2 other genera, the hepaciviruses (genus Hepacivirus, which includes hepatitis C virus and GB virus B) and pestiviruses (genus Pestivirus
, which includes bovine viral diarrhea virus and classical swine fever virus).
BVDV is classified under the Pestivirus
genus of the Flaviviridae family, has a single-stranded, 12.5-kb positive sense RNA genome, and contains an enveloped icosahedral capsid of 40-60nm in diameter (HORZINEK, 1991).
It has marked similarities to those of members of the genera Pestivirus
and Flavivirus (5).
Bovine viral diarrhea virus (BVDV) is classified in the genus Pestivirus
within the family of Flaviviridae together with other important animal pathogens such as Border disease virus (BDV) and Classical swine fever virus (CSFV) (Stahl and Alenius, 2012).
Hog cholera virus (classical swine fever) is a mechanically transmitted Pestivirus
, a genus of viruses that belong to the family Flaviviridae.
