PRV g1
The Aujeszky gI ELISA is a qualitative Blocking Enzyme-Linked Immunosorbent Assay (BELISA) for the detection of antibodies to glycoprotein I (gI) of Aujeszky's disease virus (ADV) in veterinary sera. The Aujeszky gI ELISA enables to differentiate between infected pigs and vaccinated pigs, provided the pigs are vaccinated with viruses that fail to express gI. The Aujeszky gI test makes it possible to perform sero-epizootiological studies in vaccinated swine populations to detect pigs and pig herds infected with ADV. Consequently, the use of the Aujeszky gI test in conjunction with "gI-negative" vaccines can provide the basis for combined vaccination-eradication programs for Aujeszky's disease. Apart from this application to distinguish infected from vaccinated pigs, the Aujeszky gI test may also be employed to detect infected animals in a non-vaccinated pig herd.
