Yersinia pseudotuberculosis

Test code: B0062 - Ultrasensitive qualitative detection of Yersinia pseudotuberculosis by real time PCR.


Yersinia pseudotuberculosis is a gram-negative bacterium which primarily causes disease in animals, although humans may also be infected through food contamination. Infection with this pathogen can cause tuberculosis-like symptoms, including localized tissue necrosis and granulomas in the spleen, liver, and lymph node.

The bacteria occur widely in various host species, including dogs, cats, horses, cattle, rabbits, deer, rodents, and birds. Documented cases of occupational exposure to Y. pseudotuberculosis include butchers working in abattoirs slaughtering swine. Outbreaks of Y. pseudotuberculosis in animal facilities have occasionally been reported, including in primate facilities (Bronson et al., 1972; Iwata et al., 2008).

Successfully culturing Y. pseudotuberculosis is very difficult, and serologic tests in many cases require serial testing on multiple serum samples taken at several time points. Molecular detection by PCR offers a rapid, sensitive and specific method for detecting Y. pseudotuberculosis.


  • Help confirm the disease causing agent
  • Shorten the time required to confirm a clinical diagnosis of Yersinia pseudotuberculosis
  • Help ensure that equine facilities are free of Yersinia pseudotuberculosis
  • Early prevention of spread of Yersinia pseudotuberculosis among a facility
  • Minimize human exposure to Yersinia pseudotuberculosis
  • Safety monitoring of biological products that derive from susceptible animals
