Reovirus type 3 (REO3)

Test code: S0101 - Ultrasensitive qualitative detection of reovirus type 3 by reverse transcription coupled real time PCR


Reovirus type 3 (Reo-3) can infect many different rodent species and is prevalent in laboratory rodent colonies. It is a common contaminant of transplantable tumor cell lines and other biological materials.

Infection of neonatal mice with Reo-3 can lead to a multi-systematic disease that is characterized by necrotizing hepatitis, myocarditis, pancreatitis, and meningoencephalitis. Steatorrhoea often develops secondary to liver disease and results in “oily skin” appearance.

Reo-3 virus can be transmitted between animals by aerosol and fecal–oral routes, and fomite transmission is possible because the virus is environmentally stable. One infected animal can easily lead to rapid outbreak of the disease and therefore rapid diagnosis is essential to prevent transmission through an animal facility.

Several methods are currently employed to detect Reo-3 infection in rodents and contaminated biological materials. Serological detection of anti-viral antibodies has typically been used to diagnose Reo-3 infection in rodents. However, serological assays cannot detect virus infections directly in immunodeficient strains of rodents that do not generate a humoral immune response, and even in immunocompetent rodents the time needed for seroconversion is too long for rapid diagnosis of the disease.

Molecular detection by real time PCR, on the other hand, has proven to be a useful technique for detection of Reo-3 (Steele, 1995), as it is highly sensitive and also very specific. Unlike serology testing, there is no cross-reactivity with other similar viruses. Real time PCR is also an attractive alternative to the rodent antibody production (RAP) test for detection of Reo-3 contamination in biological materials (Compton & Riley 2001). Compared to RAP testing, real time PCR offers faster turnaround time and lower cost.


  • Help confirm the disease causing agent
  • Shorten the time required to confirm a clinical diagnosis of Reo-3
  • Help ensure that vivariums are free of Reo-3
  • Early prevention of spread of this virus among a vivarium
  • Minimize personnel exposure to this virus
  • Safety monitoring of biological products that derive from mice
