Selective Delivery of Antigens by Recombinant Bacteria

Abstract
All infectious disease agents have specific mechanisms to colonize, invade, and overcome a host. If this mechanism can be defined in biochemical terms, it should be possible to develop a vaccine to prevent infection and disease. Furthermore, understanding the means by which certain bacterial pathogens target to specific lymphoid tissues in an animal host enables one to develop novel strategies for targeting foreign antigens to that specific lymphoid tissue to elicit an immune response.
