The blaNDM-1 in the Escherichia coli was located on a 176kb IncA/C plasmid contained within an ISCR1 region. The blaNDM-1 in the Providencia rettgeri was located on a 117kb IncT plasmid contained within Tn3000, while the blaNDM-1 in Pseudomonas aeruginosa was located on the chromosome within an ISCR3 region. This report highlights the plasticity of the genetic regions and environments associated with blaNDM-1. To the best of our knowledge, this is the first report of P. aeruginosa with blaNDM-1 identified in North America and the first report of blaOXA-181in P. rettgeri. The P. aeruginosa belonged to the international high risk clone ST654 and was non-susceptible to colistin. This case emphasizes the need for appropriate infection prevention and control measures and vigilant screening for carbapenem resistant Gram negative bacteria in patients with a history of travel to endemic areas, such as the Indian subcontinent.en© 2015, American Society for Microbiology.
