Three major clonal lineages (CC1, CC2 and CC149) were detected among multidrug-resistant (MDR) Acinetobacter baumannii isolates at a single institution.
The complete genome of one A. baumannii isolate belonging to the novel CC149 clonal lineage was sequenced.
These isolates contained NDM-1, OXA-23 or OXA-58 carbapenemases and 16S rRNA methylase ArmA.
MDR and extensively drug-resistant (XDR) susceptibility profiles were determined for these isolates.
