Abstract:
A modified Salmonella, wherein the wild type pag gene such as pagC has been replaced by a gene encoding a truncated pag gene such as pagC gene fused to a heterologous DNA segment, is disclosed. This modification significantly attenuates the virulence of the Salmonella. In addition, immune reaction to the portion of the fusion protein encoded by the heterologous gene can be generated. Uses of the vector, including its use in a drug screen are also disclosed.
