Abstract

Official abstract text for this publication.

The present invention provides a method of maintaining a gram negative bacterium plasmid without the use of antibiotic selection pressure. Further, the invention relates to the drugless plasmids produced including drugless plasmids containing a heterologous gene. The invention also provides formulations and/or compositions comprising the drugless plasmids comprising a heterologous gene, formulations and/or compositions comprising a protein or an immunogen expressed using the drugless plasmids, and methods of administering such formulations and/or compositions to a host. The invention relates to gram negative bacteria containing the drugless plasmids.

First claim

Opening claim text (preview).

What is claimed is: 1. A drugless plasmid comprising a polynucleotide encoding a cI repressor protein comprising the sequence of SEQ ID NO:2, wherein the expression of the cI repressor protein regulates the expression of a heterologous toxic gene product in a bacterial host. 2. The drugless plasmid of claim 1 , wherein the polynucleotide is operably linked to a promoter. 3. The drugless plasmid of claim 2 , wherein the promoter is a P1 pro…
