[Immunological methods for the diagnosis of bovine tuberculosis--state of the art].

An overview is given about the most common immunological methods for the diagnosis of bovine tuberculosis. These methods are based on cell mediated immune reactions on the one hand (intradermal skin test, interferon-gamma-test, lymphocyte transformation test) or on antibody production against Mycobacterium bovis on the other hand (ELISA). The advantages and disadvantages of the methods as well as their specificity and sensitivity are discussed.
