results in Tyzzer’s disease, which is characterized by necrotic
lesions in the liver, digestive organs and heart. A number of
animal species are susceptible to this organism, including mice,
rats, rabbits, dogs, cats, primates, and horses.
is an obligate gram-negative bacteria found in necrotic foci in

Tyzzer’s is a severe disease in many animal species, infected
mice often do not exhibit clinical symptoms. These mice become
carriers of the disease and spread the pathogen to other mice
and other animal species. Interestingly, different mouse strains
differ in their susceptibility to the pathogen (Waggie et al.,
cannot be cultivated in artificial media, so diagnosis may be
based on microscopic examination of tissues, serological assays
or steroid challenge tests; these methods all require blood or
necropsy samples. When steroid challenge assays are performed,
extreme care must be taken to avoid spreading the pathogen.
Moreover, microscopic examination, serology and steroid
challenge all suffer from a lack of sensitivity and are labor
this pathogen by polymerase chain reaction is highly sensitive
and specific. The test can be performed on fecal specimens
rather than blood or tissue, resulting in less trauma and risk

specified. Frozen specimens should be shipped so as to remain
frozen in transit. See shipping
