Antigenic variations in bovine viral diarrhea viruses detected by monoclonal antibodies

open access: yesJournal of Clinical Microbiology, 1990
Five 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

Differences in virulence between two noncytopathic bovine viral diarrhea viruses in calves

open access: yesAmerican Journal of Veterinary Research, 1992
Summary 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

Phylogenetic analysis and characterization of Korean bovine viral diarrhea viruses

Veterinary Microbiology, 2009
Thirty-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.

The Contribution of Infections with Bovine Viral Diarrhea Viruses to Bovine Respiratory Disease

Veterinary Clinics of North America: Food Animal Practice, 2010
The 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 ...

Phylogenetic analysis of bovine viral diarrhea viruses using five different genetic regions

Virus Research, 2004
Phylogenetic analysis of the five different regions (5' non-coding region (5'NCR), N(pro), E2, NS3 and NS5B-3'NCR) of 48 Japanese and reported bovine viral diarrhea virus (BVDV) genomes was performed. Japanese BVDVs were segregated into BVDV1 subdivided into six subgroups and BVDV2.

Genetic characterization of bovine viral diarrhea viruses isolated from persistently infected calves born to dams vaccinated against bovine viral diarrhea virus before breeding

American Journal of Veterinary Research, 2009
Abstract Objective—To collect and partially characterize strains of bovine viral diarrhea viruses(BVDVs) isolated from persistently infected (PI) calves born to vaccinated dams, determine genetic diversity of the isolated viruses, and identify regional distribution of genetically similar virus subpopulations.

Comparison of the p125 coding region of bovine viral diarrhea viruses

Veterinary Microbiology, 1995
The 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 ...

Genotyping of bovine viral diarrhea viruses from cattle in China between 2005 and 2008

Veterinary Microbiology, 2010
Eighteen bovine viral diarrhea viruses (BVDV) from cattle in China between 2005 and 2008 were genetically typed by sequencing of the 5'-untranslated region (5'-UTR) of the viral genome and for selected isolates the N(pro) region. Phylogenetic reconstructions indicated that all of the 18 BVDV positive samples examined in this work clustered within the ...
