Emergence of a multidrug-resistant clinical isolate of Escherichia coli ST8499 strain producing NDM-13 carbapenemase in the Republic of Korea

Abstract We described a carbapenem-resistant Escherichia coli ST8499 strain producing New Delhi metallo-β-lactamase-13 (NDM-13) from patient in Korea. The isolate exhibited multidrug resistance, but remained susceptible to colistin and tigecycline. The bla NDM-13 gene was located on a 130-kb self-transmissible plasmid. This is the first report of NDM-13 carbapenemase in Korea.
