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.
Utilities:
-
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

Specimen requirements:
Rectal swab, or 0.2 ml feces, or 0.2 ml fresh, frozen or fixed
tissue, or 0.2 ml whole blood in EDTA (purple top) tube.
Contact Zoologix if advice is needed to determine an appropriate specimen type for a specific diagnostic application. For specimen types not listed here, please contact Zoologix to confirm specimen acceptability and shipping instructions.
For all
specimen types, if there will be a delay in shipping, or during
very warm weather, refrigerate specimens until shipped and ship
with a cold pack unless more stringent shipping requirements are
specified. Frozen specimens should be shipped so as to remain
frozen in transit. See shipping
instructions for more information.
