New Delhi Metallo-β-Lactamase, Ontario, Canada
To the Editor: The New Delhi metallo-β-lactamase (NDM-1) was fi rst characterized in 2009 from Kleb-siella pneumoniae and Escherichia coli isolated from a patient in Sweden who had received medical care in New Delhi, India (1). Further studies have shown broad dissemination of this β-lactamase gene (bla NDM-1) in India, Pakistan, Bangladesh, and the United Kingdom (2). Additional isolates have ...
متن کاملNew Delhi metallo-β-lactamase-1: detection and prevention.
1240 CMAJ, August 9, 2011, 183(11) © 2011 Canadian Medical Association or its licensors The advent of New Delhi metallo-β lactamase-1 (NDM-1) as a new mechanism of microbial resistance went mostly unmarked, despite it being plasmidmediated, highly transferable and able to confer resistance to most antibiotics (with the exceptions of colistin and tigecycline). However, after the Indian subcontin...
متن کاملEpidemiology and Characteristics of Metallo-β-Lactamase-Producing Pseudomonas aeruginosa
Metallo-β-lactamase-producing Pseudomonas aeruginosa (MPPA) is an important nosocomial pathogen that shows resistance to all β-lactam antibiotics except monobactams. There are various types of metallo-β-lactamases (MBLs) in carbapenem-resistant P. aeruginosa including Imipenemase (IMP), Verona integron-encoded metallo-β-lactamase (VIM), Sao Paulo metallo-β-lactamase (SPM), Germany imipenemase (...
متن کاملStructural and kinetic studies on metallo-β-lactamase IMP-1.
In an effort to probe for metal binding to metallo-β-lactamase (MβL) IMP-1, the enzyme was overexpressed, purified, and characterized. The resulting enzyme was shown to bind 2 equiv of Zn(II), exhibit significant catalytic activity, and yield EXAFS results similar to crystallographic data previously reported. Rapid kinetic studies showed that IMP-1 does not stabilize a nitrocefin-derived reacti...
متن کاملEmergence of New Delhi Metallo-β-Lactamase, Austria
To the Editor: Extended-spectrum β-lactamase–producing Enter-obacteriaceae strains have emerged as a major public health problem throughout the world, particularly in India and Pakistan. The widespread use of carbapenems, the only agents reliably active against these bacteria, resulted in the emergence of a new resistance mechanism. New Delhi metallo-β-lactamase (NDM-1) was fi rst detected in a...
