Bovine Viral Diarrhea Viruses (BVDV) in the Feedlot
American Association of Bovine Practitioners Conference Proceedings, 2005Bovine viral diarrhea viruses (BVDV) represent significant pathogens for cattle. The BVDV affect several organ systems; however, the respiratory tract and fetal infections receive critical attention based on disease impact and potential for reservoirs/transmission.

Phylogenetic analysis and characterization of Korean bovine viral diarrhea viruses
Veterinary Microbiology, 2009Thirty-six bovine viral disease viruses (BVDVs) were identified in bovine feces (n=16), brains (n=2), and aborted fetuses (n=18) in Korea. To reveal the genetic diversity and characteristics of these Korean strains, the sequences of their 5'-untranslated regions (5'-UTRs) were determined and then compared with published reference sequences.

Comparison of the p125 coding region of bovine viral diarrhea viruses
Veterinary Microbiology, 1995The p125 (p54/p80) coding region of two cytopathic (CP) strains (Oregon and Singer) and two noncytopathic (NCP) strains (NY-1 and Draper) of bovine viral diarrhea virus (BVDV) were amplified by the polymerase chain reaction, cloned and sequenced. The sequence data confirmed that the two CP strains do not possess any insertion or deletion in their p125 ...

Propagation of Bovine Viral Diarrhea Viruses in Bovine Fetal Lung Cell Cultures
American Journal of Veterinary Research, 1975SUMMARY A procedure to prepare and maintain bovine fetal lung (bfl) cell cultures was established. These cell cultures grew abundantly and readily and were easy to handle. Monolayers could be kept in satisfactory condition in maintenance medium for 14 days.

Natural recombination in bovine viral diarrhea viruses
1994BVDV isolates exist as two biotypes differentiated at the molecular level by production of a p80 polypeptide. Insertions consisting of host cell sequences and/or duplicated and rearranged viral sequences have been observed in the portion of the genome coding for the p80 polypeptide in some, but not all, cytopathic BVDV.

Antigenic variations in bovine viral diarrhea viruses detected by monoclonal antibodies
Journal of Clinical Microbiology, 1990Five murine monoclonal antibodies (MAbs) against the NADL strain of bovine viral diarrhea (BVD) virus were developed, identified, and characterized. Four of the MAbs were directed against a 53-kilodalton (kDa) viral protein, and one was specific to a 47-kDa polypeptide. Competitive radioimmunoassay showed that two MAbs were specific to related epitopes

American Association of Bovine Practitioners Conference Proceedings, 1992
The purpose of the present study therefore, was to determine whether the clinical response to BVDV infection might be altered by the intervention of other viral infections affecting cattle, such as those induced by infectious bovine rhinotracheitis (IBR), parainfluenza-3 (PI-3) viruses, and bovid herpesvirus-4 (BHV-4).

The Contribution of Infections with Bovine Viral Diarrhea Viruses to Bovine Respiratory Disease
Veterinary Clinics of North America: Food Animal Practice, 2010The contribution of bovine viral diarrhea viruses (BVDV) to the development of bovine respiratory disease is the sum of several different factors. These factors include the contribution of acute uncomplicated BVDV infections, the high incidence of respiratory disease in animals persistently infected with BVDV, the immunosuppression that accompanies ...

Differences in virulence between two noncytopathic bovine viral diarrhea viruses in calves
American Journal of Veterinary Research, 1992Summary A noncytopathic bovine viral diarrhea virus (bvdv), bvdv-890, isolated from a yearling heifer that died with extensive internal hemorrhages, was compared for virulence in calves with noncytopathic bvdv-TGAN, isolated from an apparently healthy persistently infected calf. After challenge exposure with bvdv-890, nonimmune calves (n = 7) developed
