Abstract: In the invention described here, the approach is to formulate an edible vaccine based on N-terminal yeast surface display expression systems including S. cerevisiae EBY100/pYD5-VP28, S. cerevisiae EBY100/pYD5-VP28-VP24 and S. cerevisiae EBY100/pYD5-VP24 for preventing shrimps such as L. vannamei, P. monodon and M. rosenbergii species from white spot syndrome virus (WSSV) infection, suggesting that yeast surface display expression system expressing WSSV antigen has potential as a prophylactic treatment for WSSV in shrimps via oral vaccination. The technology developed in this patent application can also be used to produce edible (oral) vaccines for preventing and treating other infectious diseases in animals and human.

Abstract: The invention provides for anti-pathogen vaccines produced in recombinant bacteria and/or transgenic plants and administered through standard vaccine introduction methods or oral administration. In one embodiment, the vaccine is administered through the consumption of the edible plant as food, or the bacteria administered orally. The present invention also provides a method of using genetically modified microorganisms, such as lactic acid bacteria, including Lactococcus lactis strains, as oral vaccines. In one embodiment, Lactococcus lactis expressing the avian influenza HA gene can be used as an oral vaccine for protection against H5N1 virus infection. In another embodiment, said Lactococcus lactis is administered as an oral vaccine in conjunction with an adjuvant such as cholera toxin B.

Abstract: In one embodiment, the present invention provides for an edible mini-capsule form of live, non-persisting, recombinant Lactococcus lactis (L. lactis) vaccine against a pathogen such as the highly virulent influenza H5N1 strain. Enteric coated capsule of the present invention induced high levels of hemagglutinin-specific serum IgG and fecal IgA antibody production after oral administration in mice and chickens, and rendered complete protection against a lethal challenge of H5N1 virus in mice. The present invention thus demonstrates a broadly applicable platform technology for producing and administering edible vaccines against bacterial and viral infections.

Abstract: The anti-pathogen vaccine of the present invention is produced in recombinant bacteria and/or transgenic plants and then administered through standard vaccine introduction method or through the oral administration. A DNA sequence encoding for the expression of an antigen of a pathogen is isolated and ligated to a promoter which can regulate the production of the surface antigen in a bacterial or transgenic plant. Preferably, a foreign gene is expressed in a portion of the plant or bacteria, and all or part of the antigen expressing plant or bacteria used for vaccine administration. In a preferred procedure, the vaccine is administered through the consumption of the edible plant as food, or the bacteria administered orally. The present invention also provides a method of using genetically modified microorganisms generally recognized to be edible and/or harmless to animals or humans when ingested, such as lactic acid bacteria, including Lactococcus lactis strains, as oral vaccines.

Abstract: The anti-viral vaccine of the present invention is produced in transgenic plants and then administered through standard vaccine introduction method or through the consumption of the edible portion of those plants. A DNA sequence encoding for the expression of a surface antigen of a viral pathogen is isolated and ligated to a promoter which can regulate the production of the surface antigen in a transgenic plant. This gene is then transferred to plant cells using a procedure that results in its integration into the plant genome, such as through the use of an Agrobacterium tumenfaciens plasmid vector system. Preferably, the foreign gene is expressed in an portion of the plant that is edible by humans or animals. In a preferred procedure, the vaccine is administered through the consumption of the edible plant as food, preferably in the form of a fruit or vegetable juice which can be taken orally.
