| Outline of Final Research Achievements |
Enterohemorrhagic E. coli (EHEC) produces two immunologically distinct types of Shiga toxin (Stx, ie, Stx1 and Stx2). EHEC toxoid vaccines should prevent intoxication caused by both types of toxins. Using the enterotoxin B subunit stabilization technology we established before, we developed the toxoid vaccines that sufficiently neutralized Stx1 and Stx2. In addition, we produced neutralizing monoclonal antibodies using the toxoid vaccines as an immunogen.
