[Precipitation reaction and hemagglutination-hemolysis reaction in tuberculosis. II. Hemagglutination-hemolysis reaction by Middlebrook-Dubos (author's transl)].

Sera of patients with pulmonary and extrapulmonary tuberculosis, of blood donors and cattle sera were researched in hemagglutination reaction, using untreated and papain-treated sheep erythrocytes, and in hemolysis reaction. 58% of patients with pulmonary tuberculosis and 23% of normal sera, reacted positive in at least one of the 3 reactions. 24 sera of 44 patients with extrapulmonary tuberculosis were found to be positive.

Sera of patients, blood donors and cattle sera were examined by means of diffusion--in--gel technique using self produced antigens, prepared from H 37 Ra, one fresh isolated strain of M. tbc and BCG Jena. 38.
