Protection against fetal infection with either bovine viral diarrhea virus type 1 or type 2 using a noncytopathic type 1 modified-live virus vaccine.
Two bovine viral diarrhea virus (BVDV) fetal protection studies were done using a monovalent noncytopathic (NCP) BVDV vaccine containing type 1 BVDV. In study 1, thirty-two fetuses (23 vaccinates and nine controls) were recovered following fetal challenge with the type 1a BJ strain. Twenty of twenty-three fetuses from the vaccinates were negative for BVDV type 1 while all of the controls (nine ...
متن کاملSpatial analysis for bovine viral diarrhea virus and bovine herpesvirus type 1 infections in the state of Paraíba, northeastern Brazil
BACKGROUND Bovine Viral Diarrhea Virus (BVDV) and Bovine Herpesvirus type 1 (BoHV-1) cause reproductive problems in cattle and restrictions on international trade in animals worldwide. Both infections were detected in cattle herds in the Paraíba state, Northeastern Brazil, however, the spatial distribution and geographic identification of positive herds for these viruses has never been examined...
متن کاملEvaluation of the vaccine potential of an equine herpesvirus type 1 vector expressing bovine viral diarrhea virus structural proteins.
Bovine viral diarrhea virus (BVDV) is an economically important pathogen of cattle that is maintained in the population by persistently infected animals. Virus infection may result in reproductive failure, respiratory disease and diarrhoea in naïve, susceptible bovines. Here, the construction and characterization of a novel vectored vaccine, which is based on the incorporation of genes encoding...
متن کاملOnset of protection from experimental infection with type 2 bovine viral diarrhea virus following vaccination with a modified-live vaccine.
The onset of protection after the administration of a modified-live bovine viral diarrhea virus (BVDV) vaccine was determined. Protection was determined following experimental infection with a virulent type-2 BVDV (strain 1373) in cattle vaccinated 3, 5, or 7 days before BVDV infection. Protection, as measured by reduced virus shedding, lack of leukopenia, reduction in viremia, and reduced mort...
