title: Detection and identification of equine herpesvirus-1 and -4 by polymerase chain reaction.
abstract: A rapid method for detection and identification of equine herpesvirus-1 and -4 (EHV-1 and EHV-4) was developed using polymerase chain reaction (PCR). Primers for PCR were designed from aligned nucleotide sequences of glycoprotein B genes of EHV-1 and EHV-4 to amplify specific regions for EHV-1 or EHV-4 or a common region of both viruses. By using type specific primer mixture, amplified fragments were identified as EHV-1 or EHV-4 in a one-step reaction. We have applied this technique on specimens from aborted fetuses. The samples contained only EHV-1 and there was complete accordance between the results of PCR and virus isolation. Our PCR system could differentiate the two virus types rapidly in a one-step reaction.
