Abstract
The invention provides vectors, attenuated pathogens, compositions, methods, and kits for use in preventing or treating infection by an infectious pathogen, especially. The vectors comprise the plasmid encoded ppg genes from, ppg1, ppg2, ppg3, ppg5, ppg6, ppg7 and/or ppg8, but lack ppg4, a regulator of virulence associated genes. The application also provides attenuated pathogens, especially, which are cured of their plasmid and have additional mutations to improve the attenuation, especially mutations in the CT135 gene or in the tryptophan operon (trp promoter, trpA, or trpB). Uses of said nucleic acids and attenuated pathogens for inducing or modulating an immune response in a subject, especially for prevention or treatment of infections, are proposed.
