Diagnosis of Bovine Viral Diarrhea Virus Infections

Veterinary Clinics of North America: Food Animal Practice, 1995
Because 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 ...

Vaccination of cattle against bovine viral diarrhea virus

Veterinary Microbiology, 2017
Bovine viral diarrhea virus (BVDV) is responsible for significant losses to the cattle industry. Currently, modified-live viral (MLV) and inactivated viral vaccines are available against BVDV, often in combination with other viral and bacterial antigens.

Evolution of bovine viral diarrhea virus vaccines

Veterinary Clinics of North America: Food Animal Practice, 2004
Control 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 Respiratory Tract Disease Caused by Bovine Viral Diarrhea Virus

Veterinary Clinics of North America: Food Animal Practice, 1997
Although several viruses and bacteria are capable of inducing bovine respiratory tract disease, a pivotal organism in the cause of this complex disease may be bovine viral diarrhea virus (BVDV). Circumstantial evidence has long supported this hypothesis. It is frequently present in diseased respiratory tract tissues often together with other viruses or

Bovine Viral Diarrhea Virus Testing Options

American Association of Bovine Practitioners Conference Proceedings, 2003
A 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, 1976
Abstract 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
