Outbreak of bovine tuberculosis featuring anergy to the skin test, udder lesions and milkborne disease in young calves.
A severe outbreak of bovine tuberculosis in a 1300-head, multisite dairy herd in Great Britain had several unusual features, including anergy to the tuberculin skin test, milkborne disease in calves and a farm cat, and a risk of human infection. The outbreak was controlled by culling 221 cattle over 15 months, by using the gamma-interferon (gamma-IFN) test and by the examination of milk samples. The gamma-IFN test detected infected animals that were not detected by the skin test.
