We report two KPC-producing Citrobacter freundii isolates from unrelated patients. In one case, blaKPC-2 was harbored on a novel variant of a Tn4401 transposon of an IncN plasmid conjugated together with a coresident IncA plasmid, whereas in the other one, blaKPC-3 was on a Tn4401a transposon located on an IncX3-IncA self-conjugative plasmid fusion. The interplay among plasmids carrying blaKPC and the coresident IncA plasmids offers new information on plasmids coresident within clinically relevant enterobacteria.

Abstract
We report two KPC-producing Citrobacter freundii isolates from unrelated patients. In one case, blaKPC-2 was harbored on a novel variant of a Tn4401 transposon of an IncN plasmid conjugated together with a coresident IncA plasmid, whereas in the other one, blaKPC-3 was on a Tn4401a transposon located on an IncX3-IncA self-conjugative plasmid fusion. The interplay among plasmids carrying blaKPC and the coresident IncA plasmids offers new information on plasmids coresident within clinically relevant enterobacteria.File in questo prodotto:
