Bovine tuberculosis (TB) is a chronic disease of cattle and other animals caused by the bacterium Mycobacterium bovis. The disease can be transmitted to humans. It is currently not present in the Czech Republic.
Description
Bovine tuberculosis is diagnosed in the field by means of a tuberculin test. In suspect cases, samples are taken after slaughter for laboratory confirmation.
Testing is carried out by bacterioscopy, culture, histology and PCR.
Bacterioscopic examination by Ziehl-Neelsen staining is a rapid but only indicative method. Bacterioscopy is always performed with culture, but can be ordered separately.
Culture is the most sensitive method. The examination time is 2 months. In case of a positive result, the colonies are confirmed by PCR.
Samples can also be tested directly by PCR.
Histological examination is performed to observe the characteristic tissue changes, supplemented by Ziehl-Neelsen staining.
