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

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 ...

Bovine Viral Diarrhea Viruses (BVDV) in the Feedlot

American Association of Bovine Practitioners Conference Proceedings, 2005
Bovine 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.

Propagation of Bovine Viral Diarrhea Viruses in Bovine Fetal Lung Cell Cultures

American Journal of Veterinary Research, 1975
SUMMARY 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

1994
BVDV 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.

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

Effects in Calves of Mixed Infections With Bovine Viral Diarrhea Virus and Several Other Bovine Viruses

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).

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.

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).
