[Comparative study of the diagnostic value of Brucella allergens in a controlled epidemiological trial]

The diagnostic value of 4 brucellar allergens used in Burnet's test has been studied in a controlled epidemiological trial. All these preparations have proved to be specific. According to the data of complex evaluation (taking into account reactogenicity, sensitivity, and specificity), the intradermal allergen consisting of the polysaccharide/protein complex extracted from acetone-dried cells of Brucella abortus vaccine strain 19 BA has shown the highest diagnostic effectiveness both in brucellosis patients and in persons immunized against brucellosis.
