Genomic Characteristics of NDM-Producing Enterobacteriaceae Isolates in Australia and Their blaNDM Genetic Contexts.

ABSTRACT: blaNDM has been reported in different Enterobacteriaceae species and on numerous plasmid replicon types (Inc). Plasmid replicon typing, in combination with genomic characteristics of the bacterial host (e.g., sequence typing), is used to infer the spread of antimicrobial resistance determinants between genetically unrelated bacterial hosts. The genetic context of blaNDM is heterogeneous. In this study, we genomically characterized 12 NDM-producing Enterobacteriaceae isolated in Australia between 2012 and 2014: Escherichia coli (n = 6), Klebsiella pneumoniae (n = 3), Enterobacter cloacae (n = 2) and Providencia rettgeri (n = 1). We describe their blaNDM genetic contexts within Tn125, providing insights into the acquisition of blaNDM into Enterobacteriaceae. IncFII-type (n = 7) and IncX3 (n
