Of 250 clinical isolates of Escherichia coli obtained in Nepal, 38 were carbapenem resistant, with MICs of imipenem or meropenem of ≥4 μg/ml. All 38 isolates harbored the following bla NDM s: bla NDM-1 , bla NDM-3 , bla NDM-4 , bla NDM-5 , bla NDM-7 , bla NDM-12 , and bla NDM-13 Most of these isolates also harbored the 16S rRNA methylase gene(s) armA , rmtB , and/or rmtC .
