Overview on the Diagnostic Tools of Bovine Tuberculosis in Egypt

The accuracy of the tuberculin test depends on several factors, including the use of high-quality tuberculins, the format of the tuberculin test used (e.g. single intradermal comparative tuberculin test, single intradermal tuberculin test, the caudal fold test), the efficiency of the testing procedure, the mode of interpretation of the test result as well as the immunological responsiveness of the animal at the time of the test. Furthermore, negative results (the presence of non reactors animals) does not mean that the animal is not infected or free animals which is a great important issue either for the clean non infected animals or the attendances and spreading of the infective organism in the environment..
