Bovine Viral Diarrhea

1981
Bovine viral diarrhea (BVD) is an endemic infection of cattle caused by an RNA virus of the genus pestivirus of the family Togaviridae. Infection is usually inapparent but can result in abortion or congenital anomalies, respiratory signs or a frequently fatal systemic disease (mucosal disease) characterized by diarrhea, necrosis, and erosions of the ...

Bovine viral diarrhea virus genomic organization

1991
In previous work, we developed a preliminary description of the genetic organization of the prototypic pestivirus bovine viral diarrhea virus (BVDV). In order to refine this genetic map and to further elucidate the gene products and expression strategy of this virus, we have generated a broad panel of sequence-specific antibody reagents.

Immunology of Bovine Viral Diarrhea Virus

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

Immunogens of bovine viral diarrhea virus

Veterinary Microbiology, 1993
Bovine 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

Structural Proteins of Bovine Viral Diarrhea Virus

American Journal of Veterinary Research, 1975
SUMMARY 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.

Bovine Viral Diarrhea Virus: Global Status

Veterinary Clinics of North America: Food Animal Practice, 2010
Despite the success of regional bovine viral diarrhea viruses (BVDV) eradication programs, infections remain a source of economic loss for producers. The wide variation among BVDV results in differences in genotype, biotype, virulence, and types of infections. BVDV infect a range of domestic and wild ruminants. Clinical presentation varies depending on

Bovine Viral Diarrhea in the Neonatal Calf

Journal of the American Veterinary Medical Association, 1974
SUMMARY Bovine viral diarrhea (bvd) virus has been implicated in neonatal calf enteritis. Calves may become infected in utero or postnatally. In utero infection may terminate in abortion, cerebellar hypoplasia, birth of a weak calf, or clinically inapparent infection. Clinical signs in neonatal calves may include fever, leukopenia, nasal discharge, and

Epidemiology of Bovine Viral Diarrhea Virus

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

Bovine Viral Diarrhea Infection in Pregnant Swine

American Journal of Veterinary Research, 1980
SUMMARY Twenty pregnant gilts (5 groups of 4) were infected experimentally with 1 of 4 strains of bovine viral diarrhea virus (bvdv) administered intranasally-orally. Blood specimens were taken from the gilts on postinfection day (pid) 7 and cultured for virus.

Characterization of bovine viral diarrhea virus proteins

Journal of Virology, 1984
Virus-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.
