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 ...

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.

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

Noncytopathogenic Bovine Viral Diarrhea Viruses Detected and Titrated by Immunofluorescence.

Canadian journal of comparative medicine and veterinary science, 2007
Noncytopathogenic (NCP) bovine viral diarrhea (BVD) disease agents can be detected and titrated in tissue culture systems by a method employing immunofluorescence. Cytopathogenic (CP) and NCP viruses cross react with fluorescein-conjugated serum globulins produced against either CP and NCP viruses, but the fluorescence is more intense in the homologous

Dissecting the Entry Pathways of Hepatitis C and Bovine Viral Diarrhea Viruses

2007
Hepatitis C virus (HCV) and bovine viral diarrhea virus (BVDV) are closely related members of the family Flaviviridae and are important human and animal pathogens, respectively. In this work, I investigated how these viruses interact with and enter both naïve and previously infected cells, specifically, the mechanisms of superinfection exclusion, the ...

The effect of infection of hatched blastocyst bovine embryos with border disease and bovine viral diarrhea viruses.

The Southeast Asian journal of tropical medicine and public health, 2006
The effect of infection with teratogenic viruses at early stages of pregnancy is not fully understood. This study aimed to look at the effect of infection with teratogenic viruses such as bovine viral diarrhea virus (BVDV) and border disease virus (BDV), on early stage embryos at the hatched blastocyst stage.
