New Delhi metallo-ß-lactamase (NDM)–producing Enterobacteriaceae have swiftly spread worldwide since an initial report in 2008 from a patient who had been transferred from India back home to Sweden (1). Epidemiologically, the global diffusion of NDM-1 producers has been associated with the Indian subcontinent and the Balkan region, which are considered the primary and secondary reservoirs of these pathogens, respectively (1). However, recent reports suggest that countries in the Middle East may constitute another potential reservoir for NDM-1 producers (1). More than 100 NDM-producing isolates have been reported in the United States, most of which were associated with recent travel from the Indian subcontinent (2,3). We report an NDM-1–producing Klebsiella pneumoniae strain that was recovered from a patient who had been transferred from Iran to a hospital in Florida, United States.
