Development of a rapid and sensitive polymerase chain reaction assay for detection of bovine herpesvirus type 1 in bovine semen

Detection of bovine herpesvirus 1 (BHV-1) genomic sequences in bovine semen inoculated with BHV-1 by polymerase chain reaction.

Polymerase chain reaction (PCR) technique was applied to detect BHV-1 in bovine semen inoculated with BHV-1. The technique was found to be 10(6) times more sensitive than a non-isotopic dot-blot hybridization method in detecting viral genomic DNA. Of the three primer pairs used, the one chosen from glycoprotein gC appeared to be most sensitive as it could detect up to 0.01 TCID50 of BHV-1 in th...

Development and evaluation of a polymerase chain reaction assay to detect Bovine herpesvirus 1

A polymerase chain reaction (PCR) assay to detect Bovine herpesvirus 1 (BoHV-1) has been developed and evaluated. This assay was based on the amplification of a viral thymidine kinase (tk) gene fragment, for which a novel pair of primers and different PCR conditions were tested. Under optimal conditions, no amplification was observed from heterologous herpesviruses or other bovine viruses. Howe...

Detection of bovine herpesvirus-1 infection in breeding bull semen by virus isolation and polymerase chain reaction.

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 polym...

Detection of bovine herpesvirus 1 sequences in yaks (Bos grunniens) with keratoconjunctivitis, using a highly sensitive nested polymerase chain reaction.

Thirty-seven yaks (Bos grunniens) with keratoconjunctivitis and 22 healthy yaks were used to investigate the role of bovine herpesvirus 1 (BoHV-1) in keratoconjunctivitis in yaks. Nucleic acid sequences of BoHV-1 glycoproteins B and E were detected in conjunctival swabs from all yaks with keratoconjunctivitis using a nested polymerase chain reaction (PCR). In 21 yaks, BoHV-1 sequences were dete...
