Serum samples from 51 apparently healthy breeding bulls were screened for bovine herpesvirus-1 (BHV-1) antibodies using an avidin-biotin enzyme-linked immunosorbent assay, revealing a sero-positive prevalence rate of 45.09%. Semen samples were then collected from 12 of the sero-positive and 12 of the sero-negative bulls and tested for BHV-1 antigen using both a virus isolation assay and a polymerase chain reaction (PCR) assay; PCR was applied to detect BHV-1 deoxyribonucleic acid by using primers selected from the relatively conserved sequence of the gI glycoprotein gene to amplify a 468 base pair fragment. The PCR-amplified products were confirmed as BHV-1 by restriction enzyme, Dde1, which produced fragments of predictable sizes, namely 340 and 128 base pairs. Positive virus isolation test results, confirmed by virus neutralisation, found BHV-1 antigen in the semen of five sero-positive and six sero-negative bulls.
