Abstract

The authors propose a new immunoenzymatic method (ELISA) for human brucellosis diagnosis. They study in a logical way some of the parameters of the reaction realizable by macro- or microassay. The all method requires less than six hours. They use OMS recommended brucella suspension as antigen. The conjugate enzyme is peroxydase and human anti-immunoglobulins are either complete or specific IgM. The revelating substrate is obtained by association of hydrogen peroxyde with 5 amino-salicylic acid which gives the best colorimetric stability. The reading is made at 450 nm : automatically by micro-assay. Using only one sample dilution, serum quantification may be hazardous.
