Comparison of the sensitivity of the bead-based Luminex immunoassay (a) and the corresponding antigen capture ELISA (b). Assay sensitivities were determined by analysing serial dilutions of inactivated B. melitensis (16 M, γ), B. abortus (544, γ) and B. suis (1330, formalin) cells. Dashed lines indicate the assay dependent limit of detection (LOD) defined as mean blank (i.e. the no-antigen control) plus three times the standard deviation (SD)
