标题：International Standard for Anti-Brucella abortus Serum: comparison of the complement-fixing activity of the first and second International Standards and the EEC standard
摘要：Although the three standards have similar agglutinating activities, it was found that the first International Standard had about half the complement-fixing activity of the second International Standard and the EEC standard. The complement-fixing activities of the latter two standards were similar. On the basis of these results, showing that the agglutination and complement-fixation tests measure different biological activities in anti- Brucella abortus sera, the WHO Expert Committee on Biological Standardization in 1976 assigned separate unitages of agglutinating and complement-fixing activity to the second International Standard for Anti- Brucella abortus Serum.
