Rapid onset of protection against infectious bovine rhinotracheitis with a modified-live virus multivalent vaccine.
This study provides evidence that subcutaneous vaccination of cattle with a commercially available modified-live virus combination vaccine can help reduce clinical signs associated with infectious bovine rhinotracheitis infections in feedlot animals vaccinated at the time of arrival. Calves vaccinated 72 or 96 hours before challenge had reduced clinical signs, lower body temperatures, lower vir...
متن کاملDevelopment and validation of an indirect ELISA as a confirmatory test for surveillance of infectious bovine rhinotracheitis in vaccinated herds
BACKGROUND Bovine herpesvirus 1 (BoHV1) is a member of the viral subfamily of Alphaherpesvirinae that infects various species, including cattle, sheep, and goats. The virus causes infectious bovine rhinotracheitis (IBR), which is included in a European list of diseases that may require control and eradication programs. The lack of confirmatory tests affects the validity of diagnostic tools, esp...
متن کاملAssessment of the long-term effect of vaccination on transmission of infectious bovine rhinotracheitis virus in cattle herds hyperimmunized with glycoprotein E-deleted marker vaccine.
OBJECTIVE To assess long-term effects and risk factors for the efficacy of hyperimmunization protocols against infectious bovine rhinotracheitis (IBR) during a longitudinal field study of dairy and dairy-beef mixed farms. ANIMALS Approximately 7,700 cows from 72 farms. PROCEDURES Farms were assigned to 3 treatment groups (hyperimmunization groups [HIGs] 1 and 2, which were hyperimmunized wi...
متن کاملIsolation of infectious bovine rhinotracheitis virus from Mustelidae.
Herpesviruses isolated from either domesticated or wild carnivores should be immunologically compared with known viruses of this group which could have been included in the diet of the animal before being considered to be previously undescribed herpesviruses native to the carnivore in question.
متن کاملInfectious bovine rhinotracheitis.
Cattle exhibiting the vulvovaginitis form of the IBR complex are sexually mature females that do not appear ill. Signs of IPV include a thick yellow to brown vulvar discharge that attaches to the vulvar tuft of hair. The vulva is swollen and the vulvar and vaginal lining is reddened, dying and/or contains small whitish-colored pustules. The vaginal-vulvar infection causes irritation, exhibited ...
