[Use of a Brucella protein-polysaccharide antigen for the allergen diagnosis of brucellosis].
The experimental and clinical study of the allergen diagnostic properties of new Brucella protein-polysaccharide antigen in comparison with brucellin has been made in the leukocyte migration inhibition test, and its working doses have been determined. The results thus obtained suggest that Brucella protein-polysaccharide antigen has considerable diagnostic advantages over commercial brucellin, which presents vast possibilities of using this antigen for the allergen diagnosis of brucellosis in the leukocyte migration inhibition test.
