Bovine Viral Diarrhea Infection in Pigs
Journal of the American Veterinary Medical Association, 1971SUMMARY Sixty-six pigs were exposed experimentally to bovine viral diarrhea (bvd) virus. Several strains of the virus and routes of administration were utilized. The immunologic, pathologic, serologic, and virologic responses of pigs in selected groups were determined. In a group of pigs exposed twice to a field strain of virus, the serologic responses

Bovine Viral Diarrhea in the Neonatal Calf
Journal of the American Veterinary Medical Association, 1974SUMMARY 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

Bovine viral diarrhea in a newborn calf
Journal of the American Veterinary Medical Association, 1985Bovine viral diarrhea virus was believed to be the cause of ill-thrift since birth, resulting in death of a Holstein calf. Bovine viral diarrhea virus was isolated from Peyer's patches and mesenteric lymph nodes, but serum neutralizing antibodies were not detected.

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,

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

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.

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 National Animal Disease Laboratory (NADL) vaccine strain of bovine viral diarrhea virus (BVDV) genes for gp48 and p80 were expressed in Escherichia coli. The BVDV-NADL gene for gp62 was integrated into a baculovirus genome for expression in Spodoptera frugiperda (Sf-9) insect ovarian cells. The antigenicity of baculovirus expressed BVDV protein was

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 ...
