Abstract
Staphylococcal enterotoxin B (SEB), which is a bacterial superantigen produced by Staphylococcus aureus, is associated with serious diseases, including food poisoning and atopic dermatitis. This study was performed to produce about 30 kDa of recombinant SEB protein and to immunize in chickens to acquire the specific egg yolk antibody (IgY) against the recombinant SEB. Chickens were immunized with the recombinant SEB intramuscularly in the breast muscle by injection 3 times at intervals of two weeks. Serum- and egg yolk-antibody titers of hens against SEB were highest at 4 weeks after first immunization. In western blot, anti-recombinant SEB IgY was reacted immunospecifically against the recombinant SEB and commercialized SEB. These results suggested that the recombinant SEB antigen could be used as an immunogen to elicit antibody (IgY) against SEB and the anti-recombinant SEB IgY could neutralized staphylococcal enterotoxin B effectively.
