Complete Nucleotide Sequence of Two Multidrug-Resistant IncR Plasmids from Klebsiella pneumoniae
Résumé
We report here the complete nucleotide sequence of two IncR replicons encoding multidrug resistance determinants, including β-lactam ( bla DHA-1 , bla SHV-12 ), aminoglycoside ( aphA1 , strA , strB ), and fluoroquinolone ( qnrB4 , aac6′-1b-cr ) resistance genes. The plasmids have backbones that are similar to each other, including the replication and stability systems, and contain a wide variety of transposable elements carrying known antibiotic resistance genes. This study confirms the increasing clinical importance of IncR replicons as resistance gene carriers.
