Lactate dehydrogenase-elevating virus (LDV)

Test code: S0137 - Ultrasensitive qualitative detection of Lactate dehydrogenase elevating virus by reverse transcription coupled real time PCR

S0137 is included on P0029 - Mouse Essentials Panel

Lactate dehydrogenase-elevating virus (LDV) belongs to the Togaviridae family and is included in the genus Arterivirus. It is also known as Lactate Dehydrogenase Virus.  LDV is a mouse-restricted virus that  causes a lifelong persistent infection in the blood.  Mouse infections result in alterations in a number of physiological functions such as immunological responses and enzyme levels.  Such changes can severely affect experimental results.

Transmission of the virus between mice in a colony is rare.  The most frequent route of transmission is passage of contaminated stocks of tumor cells or other biological materials through the mice.  It is difficult to identify infected mice because they do not show gross clinical symptoms.

Detection of the virus by serology testing is unreliable and culture of the virus is difficult (Brinton, 1986).  Since infected mice show elevated levels of lactate dehydrogenase, detection has relied in the past on indirect determination by enzyme level.  However, hemolysis, tissue damage and freezing of plasma samples can also result in non-specific elevation of this enzyme (Brinton, 1986), so false positive results are common by this method.  As LDV persistently circulates in the blood during infection, detection of viral RNA by reverse transcription coupled PCR represents a sensitive, specific and rapid method of detection of this virus in mice.

Utilities:

  • Help confirm the disease causing agent
  • Shorten the time required to confirm a clinical diagnosis of LDV
  • Help ensure that vivariums are free of LDV
  • Early prevention of spread of LDV among a vivarium
  • Minimize personnel exposure to this virus
  • Safety monitoring of biological products that derive from mice
