Key Facts
Clinical Signs

Due to the slow development of this disease, infected animals may not show clinical signs until the later stages. The clinical signs are non-specific and may include lethargy, weakness, reduced appetite, recurrent light fever, swollen lymph nodes, cough, and/or chronic mastitis. This means that infected animals may not be easily identified.


There is no effective treatment currently.


Control of bTB generally involves identifying infected animals and removing them from the herd (test and slaughter/segregation). Movement controls, post mortem meat inspection, and legislation are also important factors. Skin testing using the single intradermal tuberculin test (which detects a delayed-type hypersensitivity reaction to the intradermal injection of tuberculin) has been used for many years around the world. Whilst there are various versions of the test used for routine screening of cattle for bTB the basic principle is the same.
