Complete sequencing of IncI1 sequence type 2 plasmid pJIE512b indicates mobilization of blaCMY-2 from an IncA/C plasmid.

ABSTRACT: Sequencing of pJIE512b, a 92.3-kb IncI1 sequence type 2 (ST2) plasmid carrying bla(CMY-2), revealed a bla(CMY-2) context that appeared to have been mobilized from an IncA/C plasmid by the insertion sequence IS1294. A comparison with published plasmids suggests that bla(CMY-2) has been mobilized from IncA/C to IncI1 plasmids more than once by IS1294-like elements. Alignment of pJIE512b with the only other available IncI1 ST2 plasmid revealed differences across the backbones, indicating variability within this sequence type.
