  • Abstract:

    1. A technique is described whereby the Brucella Ring Test for milk can usefully be applied to individual cattle. 2. Results are reported which suggest that the Ring Test on individual animals may give a very useful indication of the real status of infection in a cow (except when she was vaccinated within three to four months previously; or infected within a few weeks previously). 3. Advantage of a test which requires little technical skill and of which the results are available within an hour are pointed out. 4. The test previously utilised for the determination of infection in cattle herds are briefly reviewed. 5. Views on the mechanism of the Ring Test Reaction and its relation to antibody production in the udder are recorded.
