IS26-mediated circular blaKPC transposon in ST2483 Pseudomonas aeruginosa
An IS26-driven circular blaKPC-2 transposon is reported in ST2483 P. aeruginosa, conferring robust overexpression and stable inheritance in the donor strain, with OMVs potentially facilitating its horizontal spread, although stable maintenance in recipient cells was not demonstrated under the current assay conditions.
