Abstract

The whole-genome sequencing analysis revealed a polyclonal dissemination of NDM-1 and NDM-9 variants in Escherichia coli ( n  = 20) and Klebsiella pneumoniae ( n  = 2) in Tahiti since 2015 via interspecies transfer of three different bla NDM -carrying plasmids (IncR, IncHI2, and IncF) and patient-to-patient cross-transmission. It highlights the potential risk of importation of NDM producers in France, where French Polynesia is not considered stricto sensu a foreign country from which repatriated patients have to be screened.
