Infectious bovine rhinotracheitis (IBR)


The disease is caused by a Bovine Herpesvirus -I belonging to the family Herpesviridae and subfamily Alphaherpesvirinae. It is a DNA virus spherical in shape, enveloped and cubical in symmetry, with linear double stranded DNA of 125-235 kbp in size. The virus replicates in the nucleus and hence intra-nuclear inclusion bodies are formed. BHV-1 (infectious bovine rhinotracheitis-IBR; infectious pustular vulvovaginitis-IPVV) causes a variety of diseases in cattle, including rhinotracheitis, vulvovaginitis, abortion or balanoposthitis and conjunctivitis in cattle and buffaloes. Serology and virus isolation showed presence of this disease in India.
