Ribonucleotides in Infectious Bovine Rhinotracheitis Virus DNA

Infectious 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 ...

Susceptibility of bovine macrophages to infectious bovine rhinotracheitis virus infection.

Infectious bovine rhinotracheitis virus replicated in cultured bovine alveolar macrophages (AM). However, yields of infectious virus were low, with maximum titers approximately 100 times that of the residual inoculum. Immunofluorescence and electron microscopic studies indicated that the majority of macrophages produced viral antigen, but after infection at a multiplicity of 0.1, only 4.1% of A...

The Isolation and Identification of Infectious Bovine Rhinotracheitis Virus in Iran

Sensitivity of infectious bovine rhinotracheitis virus to ether.

The sensitivity of 12 field isolates of infectious boviine rhinotracheitis (IBR) virus and four commercial modified-live infectious bovine rhinotracheitis virus vaccine strains was determined after exposure to 20% ethyl ether (anesthetic) for 16 h at 4 c. The infectivity of five field strains was reduced by varying degrees, whereas seven were found to be resistant. Three vaccine strains were mo...

Isolation 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.
