Bovine viral diarrhea virus (BVDV) infections in pigs
Veterinary Microbiology, 2013Cattle are the natural hosts of bovine viral diarrhea virus (BVDV), which causes mucosal disease, respiratory and gastrointestinal tract infections, and reproductive problems in cattle. However, BVDV can also infect goats, sheep, deer, and pigs. The prevalence of BVDV infection in pig herds has substantially increased in the last several years, causing

The persistence of bovine viral diarrhea virus
Biologicals, 2003Bovine viral diarrhoea virus (BVDV) has a unique capacity to cause persistent infections of foetuses exposed within the first 150 days of gestation. Preventing foetal BVDV infection will aid in improved control. This unique ability gives BVDV a selective advantage allowing continual mutation and antigenic variation within cattle populations. Therefore,

Laboratory diagnosis of bovine viral diarrhea virus infections
Veterinary Clinics of North America: Food Animal Practice, 2004The past 20 years have witnessed dramatic improvements in laboratory methods for diagnosing bovine viral diarrhea virus(BVDV) infections. However, improvements in diagnostic technology have not necessarily led to improved diagnosis of BVDV at the individual animal or herd level.

Molecular biology of bovine viral diarrhea virus
Biologicals, 2013Bovine viral diarrhea viruses (BVDV) are arguably the most important viral pathogen of ruminants worldwide and can cause severe economic loss. Clinical symptoms of the disease caused by BVDV range from subclinical to severe acute hemorrhagic syndrome, with the severity of disease being strain dependent.

Biosecurity and biocontainment of bovine viral diarrhea virus
Veterinary Clinics of North America: Food Animal Practice, 2004Infection of cattle with BVDV results in a variety of clinical illnesses costly to the cattle industry worldwide. The reservoir and primary source of transmission is cattle born PI with BVDV after transplacental infection in early gestation. It is a challenge to determine with certainty whether or not BVDV is circulating among a herd of cattle.

Diagnosis of Bovine Viral Diarrhea Virus Infections
Veterinary Clinics of North America: Food Animal Practice, 1995Because of complex pathogenesis and insidious nature of BVDV infections, the laboratory diagnosis is an essential component of developing measures for the control and prevention of BVDV infections. The positive isolation of BVDV from animal submissions or from aborted fetuses should provide a strong indication for further epidemiologic investigations ...

Evolution of bovine viral diarrhea virus vaccines
Veterinary Clinics of North America: Food Animal Practice, 2004Control of bovine viral diarrhea virus (BVDV) infection is economically important to the cattle industry because the virus causes a variety of clinical diseases that adversely affect essentially all stages of the production cycle. Production losses primarily stem from reproductive failure and from immunosuppression during acute BVDV infection, which ...

Bovine viral diarrhea virus infection in wild boar
Research in Veterinary Science, 2018Bovine viral diarrhea (BVD) is one of the most economically important diseases of cattle. With its very high prevalence, cattle kept on pastures become a source of the virus for the wildlife which, due to their susceptibility, then easily can serve as a source for re-infections of cattle.

Bovine Viral Diarrhea Virus Testing Options
American Association of Bovine Practitioners Conference Proceedings, 2003A review of bovine viral diarrhea virus (BVDV) dynamics is followed by a review of test efficiency measures. BVDV diagnostic challeneges are then discussed with attention to its pathogenesis during pregnancy and fetal effects. Economic decision theory methods are then applied to evaluate BVDV testing efficiencies and outcomes given certain herd BVDV ...

Bovine viral diarrhea virus-induced abortion
Theriogenology, 1976Abstract History and Clinical Signs : There frequently is a history of a febrile disease with signs compatible with bovine viral diarrhea (BVD) in the herd just prior to the occurrence of abortions. Abortion during the first trimester is usually undetected and is recognized as repeat breeding. Gross Lesions : There are no
