title: Identification of 16S rRNA methylase-producing Acinetobacter baumannii clinical strains in North America.
abstract: Five highly amikacin-resistant Acinetobacter baumannii isolates were collected at a medical center in Pennsylvania. The aminoglycoside resistance was due to the production of the 16S rRNA methylase ArmA. Two of the isolates coproduced OXA-23 beta-lactamase and were highly resistant to carbapenems as well. The isolates were genetically closely related by pulsed-field gel electrophoresis.
