title: Equine herpesvirus type 1: detection of viral DNA sequences in aborted fetuses with the polymerase chain reaction.
abstract: Primers and probes were selected from the gene encoding glycoprotein 13 (gp 13) of equine herpesvirus 1 (EHV-1). The polymerase chain reaction (PCR) was run on infected and noninfected cultured cells and on 63 specimens from 29 aborted equine fetuses. The results were evaluated by electrophoresis and dot-blot hybridization using an oligonucleotide probe labeled with biotin. In the infected samples electrophoresis showed a PCR product of about 280 base pairs. The dot-blot hybridization confirmed that this product contained EHV-1 DNA sequences. PCR took 4 h and hybridization another 14 h; the results were thus achieved within 24 h and were highly specific for EHV-1. Close concordance was found between the results of PCR and virus isolation.
