Figure 7
Antigenicity of recombinant Shiga toxins and toxoids as assessed with calf sera harbouring naturally induced Stx-specific antibodies. Results obtained with 23 sera in the competitive ELISA are presented. Figure represents ODrel values of defined rStxWT and rStxmut samples, respectively, after pre-incubation with serum (dashed line: trend line [y = 1.179x - 10.702]).
