| Abstract: | The persistence of antibodies to glycoprotein X (gpX) in the serum of pigs experimentally infected with pseudorabies virus (PRV) was determined using an anti-gpX enzyme-linked immunosorbent assay (ELISA). Antibodies to gpX were detected for at least 365 days postchallenge in nonvaccinated pigs. Previous sensitization of pigs by vaccination with S/PRV had no apparent effect on the antibody response of pigs to gpX postchallenge. In determining previous exposure of pigs to PRV strains containing the gpX gene, the anti-gpX ELISA was highly specific, but its sensitivity was lower than the standard serological procedures currently used for detecting PRV antibodies. |
