[Serodiagnosis of human brucellosis]

On the basis of the serological study of 1000 sera obtained from patients suspected of suffering from brucellosis, the authors emphasis the theoretical data which confer upon this complement fixation reaction a greater reliability than the agglutination reaction. Using an appropriate antigenic preparation, the complement fixation reaction indeed proves to be of greater interest than the classical Wright sero-agglutination test in the diagnosis of brucellosis.
