Abstract
One embodiment provides an attenuatedstrain comprising a lysis gene or cassette operably linked to an intracellularly inducedpromoter. In one embodiment, the promoter is a promoter for one of the genes inpathogenicity island 2 type III secretion system (SPI2-T3SS) selected from the group SpiC/SsaB, SseF, SseG, SseI, SseJ, SseK1, SseK2, SifA, SifB, PipB, PipB2, SopD2, GogB, SseL, SteC, SspH1, SspH2, or SirP. In one embodiment, agene is under the regulation of an inducible promoter, wherein the gene is selected from ftsW, ftsA, ftsZ, murE, mukF, imp, secF, eno, hemH, tmk, dxs, uppS, cdsA, accA, pssA, msbA, tsf, trmD, cca, infB, rpoA, rpoB, rpoC, holA, dnaC, or eng. In one embodiment, thestrain further comprises a plasmid that expresses DNA, shRNA, non-coding RNA and/or a peptide.
