K virus

Test code: S0160 - Ultrasensitive qualitative detection of K virus by real time PCR

S0160 is included on P0029 - Mouse Essentials Panel

Mouse K virus was first discovered by Lawrence Kilham - thus “K” virus. It belongs to the family Pavovaviridae. The virus is usually spread by the oronasal route.  When a young mouse is orally inoculated with the virus, the virus first replicates in the intestine and then spreads to other organs such as liver, lung, spleen and brain. Older mice may mount an immune response to the virus and thus may limit the spread of the virus through the body. However, athymic or nude mice suffer significantly if infected.

In naturally infected colonies of mice, significant clinical symptoms are usually absent and these infected mice may become carriers of the virus (Lussier and Descôteaux, 1986) and pass it to young mice.

Diagnosis of mice infected with K virus is sometimes done by serology testing. However, since many mice may have had prior exposure to this virus, a positive serology result may not indicate current carrier status.  Molecular detection by PCR can provide rapid, highly sensitive, highly specific identification of the presence of the virus.


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