Enterobacter cloacae harbouring bla KPC-2 and qnrB-1 isolated from a cystic fibrosis patient: a case report.

We describe the first detection of a KPC-2- and QnrB-producing Enterobacter cloacae from a patient with cystic fibrosis. The bla KPC-2 and qnrB-1 genes were located in a 79.8-kb plasmid. The presence of bla KPC-2 and qnrB-1 genes was determined by PCR and sequencing. Mobilization of plasmid containing bla KPC2 gene was assayed by conjugation.
