Plasmid and chromosomal integration of four novel blaIMP-carrying transposons from Pseudomonas aeruginosa, Klebsiella pneumoniae and an Enterobacter sp.

Abstract

Complex events of transposition and homologous recombination have occurred during the original formation and further plasmid and chromosomal integration of these four transposons, promoting accumulation and spread of antimicrobial resistance genes.
