Bacillus-fermented Natto as Edible Vaccines

Michael Chan of the Ohio State Research Foundation in the U.S. will develop an engineered strain of bacteria used to ferment beans in traditional Asian and African diets, to display an antigen from the Tuberculosis bacterium. The engineered bacillus will then be used to make the traditional Asian dish natto, which can serve as a kind of oral vaccine to elicit a strong immune response. If successful, this strategy can be used to introduce a variety of disease antigens through culturally accepted foods.
