Infectious bovine rhinotracheitis (IBR) is a highly contagious, infectious disease that is caused by bovine herpesvirus-1 (BHV-1). In addition to causing respiratory disease, this virus can cause conjunctivitis, abortions, encephalitis and generalized systemic infections. Although clinical findings may be highly suggestive of IBR, no real pathognomonic signs provide a clinical diagnosis for IBR. Therefore, laboratory confirmation is necessary to identify BHV-1 infection. Confirmation of exposure to BHV-1 is facilitated by measurement of antibody in serum, plasma or milk. Countries that have IBR control programs require IBR-free certification prior to shipping cattle to their regions. ELISA is the test procedure of choice in many European IBR programs. 

The Kernel IBR gE Ab Test is an enzyme-linked immunosorbent assay (ELISA) that can be an effective differential test distinguishing naturally infected from vaccinated cattle when used in IBR control programs together with gE-deleted IBR vaccines. 


The Kernel IBR gB Ab Test is an enzyme-linked immunosorbent assay (ELISA) for the detection of glycoprotein-B-specific antibodies to bovine herpesvirus-1 (BHV-1) in bovine samples using IBR gB-specific monoclonal antibodies.
