Versatile allelic replacement and self-excising integrative vectors for plasmid genome mutation and complementation.

Abstract excerpt

IMPORTANCE: In spite of the dissemination of multidrug-resistant plasmids among Gram-negative pathogens, including those carrying virulence genes, vector tools for studying plasmid-born genes are lacking. The allelic replacement vectors can be used to generate plasmid or chromosomal mutations including markless point mutations. This is the first report describing a self-excising integrative vector that can be...
