Vaccination of animals with gE-deleted vaccine strains (gE- marker vaccines) and differential detection of vaccinated vs infected animals with antibody ELISA targeting the gE or the gB proteins have been proved to be useful tools in programs for control and eradication of the bovine herpesvirus 1 (BoHV-1) responsible for infectious bovine rhinotracheitis (IBR), a major pathogen of cattle. The diagnostic sensitivity (DSe) and specificity (DSp) of three commercial gE ELISA kits from IDEXX, IDVet and CIV-HIPRA were compared for serum and milk matrices. Limiting the analysis to 198 individual with concordant ELISA results in serum (91 naïve, 37 vaccinated and 70 infected) the DSe of gE kits was estimated to 0,97 for IDEXX, 0,93 for CIV-HIPRA and 0,53 for IDVet using milk samples and the DSp to 0,95 for IDEXX, 1,00 for IDVet and CIV-HIPRA. The applicability of gE ELISA for individual or bulk milk testing as an additional tool in control programs dedicated to the certification and control of vaccinated herds was evaluated. Two of the three evaluated gE ELISA kits presented substantial to good agreement individual milk and serum samples. The bulk-tank milk also proved to be suitable for the detection of BoHV-1 in vaccinated herds provided that gE prevalence is superior to 10% as false negative results are often observed at lower gE herd prevalence. This limitation could be reduced to 8% of prevalence when a prior concentration step was applied to bulk milk samples.
