Radial immunodiffusion test with a Brucella polysaccharide antigen for differentiating infected from vaccinated cattle.

With this serological test, cattle infected with Brucella abortus could be identified in recently vaccinated herds which had high numbers of reactors to standard diagnostic tests.
