Advice and diagnosis for controlling and eradicating bovine tuberculosis

The eradication of bovine tuberculosis, which is a zoonosis caused by Mycobacterium bovis, constitutes one of the essential bases for the establishment of the intracommunitary livestock market, its meats and products, as well as for the increase in livestock productivity and, as a result, improvement of livestock producers’ income.

The eradication plan for this disease is based on an intensification of the diagnostic controls of the ruminants present on positive farms, on implementing diagnostic tests and on minimising the time positive animals remain on affected farms.

CReSA collaborates with the Department of Agriculture, Food and Rural Action (DAR) of the Generalitat of Catalonia in the eradication campaign of bovine tuberculosis, by diagnosis as well as by epidemiological assessments .


  • γ-Interferon tests of herds included within the eradication plan
  • Anatomical-pathological diagnosis of tuberculosis
  • Standardisation and validation of an indirect ELISA technique for diagnosing tuberculosis in cattle by detecting anti-PPD antibodies. This test is now being used in test herds


  • Epidemiological study on the minimum time between intradermal tuberculinization and interferon-γ tests
  • Report of the potential causes of errors in the diagnostic techniques for bovine tuberculosis
  • Design of a data base for bovine tuberculosis
  • Epidemiological study on the influence of the presence of goats on the risk of bovine tuberculosis (mixed farms)
