CTB and LTBs expressed in corn (Tacket et al. 2004), maize (Karaman et al. 2012) and rice seeds (Nochi et al. 2007; Yuki et al. 2013) alone or in combination have been used to evaluate the use of corn as an edible agent against cholera and traveler’s diarrhea. This evidence concerns the gene CTBS and vibrio infectious disease.
