Bovine viral diarrhea (BVD), bovine viral diarrhoea (UK English) or mucosal disease, previously referred to as bovine virus diarrhea (BVD), is an economically significant disease of cattle that is found in the majority of countries throughout the world. [1] .

What is Bovine Viral Diarrhea? Bovine Viral Diarrhea (BVD) is a disease of cattle caused by the Bovine Viral Diarrhea Virus (BVDV). The virus is widespread, and most herds are at risk for infection. In the susceptible herd, BVD can be a serious, costly disease.

BVDV type 1 and type 2 appear to be distributed worldwide; however, the prevalence of each type of virus varies considerably among regions. The distribution of viral subgenotypes is more restricted, with many viral subgenotypes being found only in certain regions of the world and, in some cases, only certain regions of a country. ...

Control of bovine viral diarrhea virus (BVDV) in cattle populations across most of the world has remained elusive in spite of advances in knowledge about this viral pathogen. A central feature of virus perseverance in cattle herds is the unique mechanism of persistent infection.

Bovine viral diarrhea (BVD) is a contagious viral disease of cattle and other ruminants. The disease was first seen in 1946 in New York as a gastro-enteritis with severe diarrhea, ulcerations of the muzzle and nasal and oral cavities, fever, leukopenia, reduction in milk production, cessation in rumination, and abortions.

Cattle of all ages are susceptible to infection with bovine viral diarrhoea virus (BVDV). BVDV is a single linear positive-stranded RNA virus in the genus Pestivirus of the family Flaviviridae.

BVDV type 1 (pestivirus A), BVDV type 2 (pestivirus B), and Hobi-like viruses (pestivirus H) cause major clinical respiratory and reproductive disorders in cattle worldwide. Initial attempts to control BVDV by vaccination used several BVDV type 1 isolates such as Singer, NADL and C24V.

Bovine Viral Diarrhea Virus (BVDV) is a contributor (along with others) to what is known as “shipping fever,” a complex or bovine respiratory disease (BRD). This virus may also produce enteric disease (diarrhea) and reproductive disease like abortion and stillbirth.

2020年6月10日 · Bovine Viral Diarrhea Virus (BVDV) is among the most important pathogens affecting today’s beef and dairy cattle operations. Associated with reproductive, digestive, and respiratory illnesses in cattle, the virus can also create a congenital, persistent infection in calves, greatly aiding the virus’ spread within and between herds.

Bovine viral diarrhoea virus (BVDV) in cattle is a complex disease that is caused by bovine pestivirus. Bovine pestivirus and its resulting diseases have several interchangeable names including bovine viral diarrhoea (BVD), pestivirus and bovine pestivirus.
