  • Publication number: 20220218810
    Abstract: The present invention relates to an immunogenic composition for Proteobacteria protection and reduced transmission. We have identified Proteobacteria serovar variant 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 positions 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.

  • Patent number: 6664386
    Abstract: Provided is a signal peptide comprising an amino acid sequence at least 90% homologous to the amino acid sequence as shown in SEQ ID NO:1. Further provided is a fusion protein comprising the signal peptide fused to a heterologous protein. Also provided are nucleic acid molecules encoding the signal peptide and encoding the fusion protein, as well as vectors and recombinant host cells comprising the nucleic acid molecules. The recombinant host cell can be a recombinant bacterium having a functional type III secretion system and having loss-of-function mutations in genes that encode secreted substrate proteins of the type III secretion system. The recombinant host cell can be used in a method of producing the heterologous protein.
