Objectives: This study describes the first draft genome sequence of a multidrug- resistant (MDR) Escherichia coli D-ST69 clinical isolate from Egypt carrying blaNDM-1 and blaOXA-244.Methods: The strain was isolated in December 2014 from a wound pus swab of a male patient in the city of Kafr El-Sheikh using MacConkey agar containing 2 μg/mL meropenem. The strain was subjected to antimicrobial susceptibility testing, conjugation experiments, and whole-genome sequencing using an Illumina MiSeq platform.Results: The draft genome of the strain (HR14_AS) was 5.08 Mbp in size containing a total of 90 contigs encoding 4677 predicted genes with an average G+C content of 50.7%. Strain HR14_AS belongs to sequence type 69 (ST69), phylogroup D and exhibits an MDR phenotype, with minimum inhibitory concentrations (MICs) of 64 μg/mL and 32 μg/mL for meropenem and doripenem, respectively. Multiple acquired antimicrobial resistance genes conferring resistance to macrolides [mdf(A)], fluoroquinolones [aac(6')-Ib-cr], quinolones (qnrS1), trimethoprim (dfrA14), β-lactams (blaNDM-1, blaOXA-244, blaCTX-M-15, blaOXA-9 and blaTEM- 1B) and aminoglycosides [aac(3)-IId, aac(6')-Ib, aadA1 and aph(3')-VI] were detected. The blaOXA-244 and blaNDM-1 genes were located on the chromosome (Tn6237) and on an IncI1-type self-conjugative plasmid of >93 kb in size, respectively.Conclusions: Here we report the first draft genome sequence of a MDR E. coli D-ST69 isolate carrying blaNDM-1 and blaOXA-244. Besides clonal expansion of the E. coli ST38 pandemic clone, this study further identified that the spread of OXA- 244-producing E. coli could be related to mobilisation of the IS1R-made composite transposon (Tn6237) carrying blaOXA-244.
