First identification of a patient colonized with Klebsiella pneumoniae carrying blaNDM-1 in Taiwan.

New Delhi metallo-ß-lactamase 1 (NDM-1) is a novel type of metallo-ß-lactamase (MBL). Enterobacteriaceae carrying this NDM-1 encoding gene, bla(NDM-1), have been identified worldwide. Bacteria carrying bla(NDM-1) are not only resistant to carbapenem, but also highly resistant to many classes of antibiotics, which indicate the importance of prompt identification of these bacteria and implementation of strict infection control measures to prevent their transmission. Here, we report the first identification and management of a patient colonized with Klebsiella pneumoniae carrying bla(NDM-1) in Taiwan, who returned from New Delhi where he had been hospitalized for a gun-shot injury.
