The Isolation and Identification of Infectious Bovine Rhinotracheitis Virus in Iran

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.

Sequencing and Phylogenetic Analysis of Infectious Bovine Rhinotracheitis Virus Gb and Gd Genes in Iran

Bovine herpesvirus 1 (BHV-1) belongs to the Varicellovirus genus, Herpesviridae family and causes different respiratory, reproductive and nervous system disorders in cows, including infectious bovine rhinotracheitis (IBR). For determination of the genetic relationship of gB and gD – two of main BHV-1 glycoprotein genes in Iran with those in other countries, DNA fragments of 671 bp corresponding...

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...

Isolation and Identification of Infectious Bronchitis Virus from Commercial Chickens

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 ...

Isolation of Infectious Bovine Rhinotracheitis Virus in Cell Culture: (a Case Study)

Infectious bovine rhinotracheitis is an important disease of cattle with serious economic implications. The etiology is bovine herpes virus type-1 which leads to clinical to latent infections and abortions. In this study, an aborted bovine fetus was suspected of IBR infection. The virus was grown in cell line (MDBK) and cytopathic effect observed. CPE began at 12 hr post infection of cells and ...
