Studies on genetic diversity of bovine viral diarrhea viruses in Danish cattle herds

Virus Genes, 2013
Scandinavian countries have successfully pursued bovine viral diarrhea virus (BVDV) eradication without the use of vaccines. In Denmark, control and eradication of BVDV were achieved during the last two decades, but occasionally new BVDV infections are detected in some Danish cattle herds.

Bovine Viral Diarrhea Viruses (BVDV) in Beef Breeding Herds and Feedlots

American Association of Bovine Practitioners Conference Proceedings, 2007
Bovine viral diarrhea viruses (BVDV) represent significant pathogens in cattle affecting several organ systems, particularly involving the respiratory tract and fetal infections. The principal reservoir of BVDV is the persistently infected (Pl) animal. The PI cattle are born to susceptible heifers/cows exposed during pregnancy, carried to term, and are

Competitive virus assay method for titration of noncytopathogenic bovine viral diarrhea viruses (END+ and END− viruses)

Journal of Virological Methods, 2013
A new, reliable and secure virus assay method, named the competitive virus assay (CVA) method, has been established for the titration of bovine viral diarrhea viruses (BVDVs) that either show the exaltation of Newcastle disease virus (END) phenomenon or heterologous interference phenomenon (but not the END phenomenon).

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.

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 ...

Genotyping of bovine viral diarrhea viruses (BVDV) isolated from cattle in Sicily

Comparative Clinical Pathology, 2011
Bovine Viral Diarrhea–Mucosal Disease (BVD–MD) is a widely spread infectious disease that causes important economic losses in farms. Several epidemiological studies indicate a high genetic heterogeneity among Bovine Viral Diarrhea Virus (BVDV) strains circulating in Italy.

CONDITIONS FOR THE INACTIVATION OF INFECTIOUS BOVINE RHINOTRACHEITIS AND BOVINE VIRAL DIARRHEA VIRUSES FOR THE PRODUCTION OF A VACCINE

МИКРОБИОЛОГИЯ ЖӘНЕ ВИРУСОЛОГИЯ
Infectious bovine rhinotracheitis (IBR) and bovine viral diarrhea (BVD) are among the most widespread and economically significant viral diseases affecting cattle. These infections lead to reduced productivity, immunosuppression, respiratory and reproductive disorders, and substantial economic losses in livestock farming.

[Cytopathogenic bovine viral diarrhea viruses induce apoptosis in bovine cell cultures].

DTW. Deutsche tierarztliche Wochenschrift, 1998
The pestivirus bovine viral diarrhea (BVD) virus is the causative agent of Mucosal Disease (MD) of cattle. From persistently infected animals, only the non-cytopathogenic biotype BVD virus can be isolated. Cattle succumbing to MD additionally harbour cytopathogenic BVD virus.

Maternal Immunity to Infectious Bovine Rhinotracheitis and Bovine Viral Diarrhea Viruses: Duration and Effect on Vaccination in Young Calves

American Journal of Veterinary Research, 1978
SUMMARY The immune response to modified live-virus bovine viral diarrhea (bvd) vaccine and infectious bovine rhinotracheitis (ibr) vaccine was examined in calves that had received passive maternal antibodies to these viruses. Blood serum samples from vaccinated and control (nonvaccinated) calves were examined for more than 1 year to determine the rate ...
