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.

[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 ...

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.

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.

Safety and efficacy of vaccination of seronegative bulls with modified-live, cytopathic bovine viral diarrhea viruses

Theriogenology, 2009
The objectives were to vaccinate peri-pubertal bulls with a modified-live vaccine consisting of cytopathic BVDV strains Singer and 296 and evaluate the resulting: (a) transient shed of modified-live, cytopathic BVDV in semen; (b) risk of prolonged testicular infection; and (c) protection against subsequent testicular infection due to viral challenge ...

Border Disease-like Syndrome in Lambs: Antibodies to Hog Cholera and Bovine Viral Diarrhea Viruses

Journal of the American Veterinary Medical Association, 1973
SUMMARY Serum samples were collected from fetal and new-born lambs with a naturally occurring border disease-like syndrome and from lambs inoculated with brain-spleen suspensions obtained from affected lambs. Serum neutralization (sn) tests for antibodies to bovine viral diarrhea (bvd) and hog cholera viruses and the single radial immunodiffusion assay
