Characterization of the pJB12 Plasmid from Pseudomonas aeruginosa Reveals Tn6352, a Novel Putative Transposon Associated with Mobilization of the blaVIM-2-Harboring In58 Integron

The blaVIM-2-carrying In58 integron has been linked to a chromosomal location in different bacterial species, including Pseudomonas aeruginosa. This work reports the first fully sequenced In58-harboring plasmid, which is significantly different from the two previously identified blaVIM-2-carrying pl...

Summary:The blaVIM-2-carrying In58 integron has been linked to a chromosomal location in different bacterial species, including Pseudomonas aeruginosa. This work reports the first fully sequenced In58-harboring plasmid, which is significantly different from the two previously identified blaVIM-2-carrying plasmids in P. aeruginosa. blaVIM-2 might have been acquired by transposition of Tn6352, a novel transposon composed of the In58 and ISPa17 elements. The recognition of similar inverted repeat (IR) sites by ISPa17 reveals a common mobilization process associated with acquisition of the blaVIM-2 and blaVIM-1 genes.
