FIELD: biology.
SUBSTANCE: invention refers to biology, particularly immunology. Method of life-time diagnosis of cattle tuberculosis is proposed. Polymorphonuclear leukocytes are used from cattle not responding to PPD-tuberculin, from farms unfavourable by tuberculosis. Tuberculosis antigen is represented by the tuberculosis allergen recombinant diaskin-test and PPD-tuberculin for mammals in dilution 1:50.
EFFECT: invention provides higher reliability of life-time diagnosis of tuberculosis by additional detection of a tuberculosis agent in the modified L-form in animals not responding to PPD-tuberculin, from an unfavorable tuberculosis farm, that promotes more qualitative performance of veterinary-diagnostic measures and further health improvement, prevents recurrences.
