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.

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.

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 virus is the most important viral pathogen of the bovine fetus. After birth it is responsible for two clinically dissimilar conditions: BVD and mucosal disease. It also causes significant losses as a result of its interaction with other pathogens, enhancing their morbidity in dual infections.

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.

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
1991In 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, 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 ...

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

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.
