Porcine lymphotropic herpesviruses 1 and 2

Test code:
S0129 - Ultrasensitive qualitative detection of porcine lymphotropic herpesviruses 1 and 2 by real time PCR. Assay detects but does not differentiate PLHV-1 and PLHV-2. Assay does not detect PLHV-3.


Herpesviruses are widely distributed and have been found in insects, reptiles, amphibians and every species of bird and mammal. One important characteristic of herpesvirus infection is that the virus persists in the infected host for life and is frequently reactivated and shed. In pigs, five herpesviruses have been identified: pseudorabies virus, porcine cytomegalovirus (PCMV) and three recently identified lymphotrophic herpesviruses, PLHV-1, PLHV-2 and PLHV-3.

PLHV-1 and -2 are highly homologous to each other but not to PLHV-3. The two viruses are widespread in domestic pigs and are closely related to several ruminant gammaherpesviruses, most of which are etiologically implicated in the occurrence of malignant catarrhal fever (MCF), a lymphoproliferative inflammatory disease with an often fatal outcome. PLHV-1 and -2 are also related to Epstein-Barr Virus, Human Herpesvirus-8 and other gammaherpesviruses.

A recent study (McMahon et al., 2006) in domestic pigs has shown that PLHV1 infections are most common, being found in 74% of animals tested, followed by PLHV3 at 45% and PLHV2 at 21%. Infections with multiple PLHV species were frequently detected.

Like porcine CMV, antibodies to PLHV have been found in a high percentage of swine herds worldwide. Because of the high prevalence of positive serology, serological identification of infected pigs is not possible. Many of these latent carriers remain unidentified, posing serious problems for research using the pig as a model. In xenotransplantation between pig and human, reactivation of these latent viruses can cause postransplantation failure. Molecular detection of these viruses is an important tool to provide rapid, sensitive and specific detection of the viral nucleic acid in suspected animals.


  • Help confirm the disease causing agent
  • Identify PLHV-1 and -2 carriers
  • Help ensure that animal colonies and populations are free of PLHV-1 and -2
  • Early prevention of spread of these viruses among animals
  • Minimize human exposure to these viruses
  • Safety monitoring of biological products that derive from animals
