Equine herpesvirus type V (EHV-5)

Test code:
S0075 - Ultrasensitive qualitative detection of equine herpesvirus type V by real time polymerase chain reaction


Equine herpesvirus type 2 (EHV-2) and type 5 (EHV-5) were recently re-classified as members of the gamma herpesviridiae family (Browning and Studder, 1987; Telford et al., 1993). Unlike EHV-2, which is widely spread in horse populations worldwide, EHV-5 has so far only been isolated in a few countries, including Switzerland, Germany, Australia and New Zealand. In Australia, EHV-5 was originally discovered in horses suffering from upper respiratory disease (Browning and Studdert, 1987). A difference in the prevalence of EHV-2 and EHV-5 was also observed in Australia where 31 % of the tested horses were positive to EHV-2 while only 16 % were positive to EHV-5.

Studies have shown that EHV-5 infection is very common in young horses and EHV-5 infections persist in young horses for at least several months. However, EHV-5 is not specifically associated with respiratory disease. In contrast, EHV-2 is less commonly isolated from young horses and its detection is associated with the occurrence of mild respiratory disease.

Serological separation of EHV-2 and EHV-5 is very difficult because of the high degree of similarity in their protein sequences. Reliable differentiation of EHV-5 and EHV-2 relies on molecular detection methods. PCR is the most sensitive and specific technique for detection of each of these viruses.


  • Help confirm the disease causing agent
  • Shorten the time required to confirm a clinical diagnosis of EHV-5 infection
  • Help ensure that horse populations are free of EHV-5
  • Early prevention of spread of this virus
  • Minimize personnel exposure to this virus
  • Safety monitoring of biological products that derive from horses
