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

摘要

The bla(VIM-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 bla(VIM-2)-carrying plasmids in P. aeruginosa. bla(VIM-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 bla(VIM-2) and bla(VIM-1) genes.
