Bovine herpesvirus 4

Test code: S0217 - Ultrasensitive detection of bovine herpesvirus type 4 by real time PCR

Bovine herpesvirus 4 (BHV 4) belongs to genus Rhadinovirus of subfamily gammaherpesvirinae in the Herpesviridae family.

Ruminants infected by BHV 4 may develop respiratory or ocular clinical symptoms, such as rhinitis, conjunctivitis, tracheitis, or even pneumonia. Skin damage, gastrointestinal problems and genital disorders have also been reported to be associated with infection by this virus. In female animals, the virus causes vulvovaginitis, abortion and endometritis; in male animals, the virus causes epididymitis or orchitis. However, some infected animals may have no clinical symptoms, and only some strains of the virus are pathogenic in cattle.  Infection can result in latent infection, with reactivation caused by poor hygiene or rearing practices, or other stressors.

Because infection with this virus can lead to concurrent or subsequent bacterial metritis, large economic loss may result due to death, delayed breeding and infertility, discarded milk from antibiotic therapy, and decreased milk production.

Serological detection is not suitable to determine animals’ immune status because seroprevalence of this virus is high, and also the serology test may not be able to detect latent infections. Molecular detection by polymerase chain reaction (PCR) is rapid, sensitive and specific, and can detect some latent infections (Peshev and Christova, 2013).


  • Help confirm the disease causing agent
  • Identify BHV4 virus carriers
  • Help ensure that herds are free of BHV4
  • Early prevention of spread of the virus among animals
  • Minimize human exposure to the virus
  • Safety monitoring of biological products that derive from animals

Specimen requirements: 0.2 ml whole blood in EDTA (purple top) or ACD (yellow top) tube, or lesion swab or scab, or 0.2 ml milk, or nasal or conjunctival swab, or 0.2 ml fresh, frozen or fixed tissue.

Contact Zoologix if advice is needed to determine an appropriate specimen type for a specific diagnostic application. For specimen types not listed here, please contact Zoologix to confirm specimen acceptability and shipping instructions.

For all specimen types, if there will be a delay in shipping, or during very warm weather, refrigerate specimens until shipped and ship with a cold pack unless more stringent shipping requirements are specified. Frozen specimens should be shipped so as to remain frozen in transit. See shipping instructions for more information.
