Abstract
The invention concerns a method of prophylactically treating a host against infection by a microorganism, which method comprises administering to the host an attenuated Salmonella bacterium which contains a nirB promoter operably linked to a DNA sequence encoding a heterologous protein. The heterologous protein is expressed in the host and induces in the host an immune response against the microorganism.
