Figure 7From: Evaluation of biological safety in vitro and immunogenicity in vivo of recombinant Escherichia coli Shiga toxoids as candidate vaccines in cattle 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]).Back to article page
