Laboratory diagnosis of bovine viral diarrhea virus
Biologicals, 2013The control and eventual eradication of bovine viral diarrhea virus (BVDV) have been defined as objectives to reduce the economic losses due to the presence of this virus in the cattle population. These goals could not be envisioned without the significant achievements in the diagnostic procedures employed to detect the infection in its various ...

Morphology of bovine viral diarrhea virus
American Journal of Veterinary Research, 1984SUMMARY The morphology of bovine viral diarrhea virus (bvdv) was studied by electron microscopy. The NADL strain of bvdv was plaque purified 3 times, concentrated by polyethylene glycol precipitation, and purified by centrifugation to equilibrium in continuous potassium tartrate density-gradients.

The purpose of this study was to detect and confirm PI dairy cattle, research the dam's location during the first trimester of gestation, and genetically sequence a portion of the 5' untranslated (UTR) region of viral RNA to determine the prevalence of different genotypes of BVDV PI dairy cattle in the upper midwestern United States.

Characterization of bovine viral diarrhea virus proteins
Journal of Virology, 1984Virus-specific proteins were examined in cultured cells infected with bovine viral diarrhea virus. By using antisera obtained from virus-infected animals, three major virus-specific polypeptides with molecular weights of 115,000 (115K), 80K, and 55K were observed. Minor proteins of 45,000 and 38,000 daltons were also noted.

Epidemiology of Bovine Viral Diarrhea Virus
Veterinary Clinics of North America: Food Animal Practice, 1995Prevalence studies around the world show that BVDV is widespread in most cattle raising countries. There are significant differences, however, in prevalence between areas, probably the result of differences in cattle population structure and management practice.

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,

Structural Proteins of Bovine Viral Diarrhea Virus
American Journal of Veterinary Research, 1975SUMMARY A procedure for the purification of radioactively labeled bovine viral diarrhea virus was critically evaluated. Purification of virus from artificial mixtures of unlabeled infected and labeled noninfected cells indicated that the extent of purification was approximately 100-fold with respect to host proteins.

Immunogens of bovine viral diarrhea virus
Veterinary Microbiology, 1993Bovine viral diarrhea virus (BVDV) is a ubiquitous pathogen of cattle that induces economically important diseases affecting multiple organ systems. In the United States, over 150 biological products are licensed for control of BVDV. These products contain live or killed BVDV, and many products contain other viruses or bacteria. Potency tests for these

Immunology of Bovine Viral Diarrhea Virus
Veterinary Clinics of North America: Food Animal Practice, 1995Often persistent and primary postnatal infections with BVDV result in immunosuppression in cattle, thereby enhancing the vulnerability of the latter to secondary infections. The evidence for and nature of impaired immunity in these animals is reviewed. Our knowledge of the extent and nature of protective immunity induced by natural BVDV infections and ...

Bovine viral diarrhea (BVD) is prevalent worldwide and causes high economic losses in cattle due to a variety of disease syndromes. BVD is caused by three bovine pestiviruses, bovine viral diarrhea virus 1 (BVDV-1), BVDV-2 and HoBi-like pestivirus (HoBiPeV) with considerable genetic and antigenic heterogeneity.
