    摘要: The present invention relates to an immunogenic composition for Proteobacteria protection and reduced transmission. We have identified Proteobacteria strain combinations that generate an immune response capable of robustly driving bacterial enteropathogens into an evolutionary dead end and reducing the transmission of the bacterium. These inactivated immunogenic compositions and typically oral vaccines are easy to apply, cheap to produce, and can be stored long-term without cold-chain requirements making them ideal for application in livestock, or in resource-poor areas. They are believed to be the only immunogenic compositions and vaccine formulations capable of breaking the chain of transmission for these types of pathogen.
