New delhi metallo-beta-lactamase (ndm)–producing klebsiella pneumoniae are resistant to extended-spectrum antimicrobials, including carbapenems the resistance mechanism is highly transmissible and its presence substantially limits treatment options. New delhi metallo-beta-lactamase-1 (ndm-1)  is an enzyme that makes bacteria resistant to a broad range of beta-lactam antibiotics these include the antibiotics of the carbapenem family, which are a mainstay for the treatment of antibiotic-resistant bacterial infections. 'new delhi metallo-beta-lactamase,' or, 'ndm-1,' is the name given to an enzyme discovered in 2009 that is able to be produced by a number of genera of bacteria that render the bacteria resistant to several antibiotics in use around the world today.

New delhi metallo-beta-lactamase 1 (ndm-1) is an enzyme that makes bacteria resistant to a broad range of beta-lactam antibiotics these include the antibiotics of the carbapenem family, which are a mainstay for the treatment of antibiotic-resistant bacterial infections. Ndm-1 (new delhi metallo-β-lactamase) (class b) main article: new delhi metallo-beta-lactamase originally described from new delhi in 2009, this gene is now widespread in escherichia coli and klebsiella pneumoniae from india and pakistan. New delhi metallo-beta-lactamase (ndm-1) ndm-1 is an enzyme that makes bacteria resistant to a broad range of beta-lactam antibiotics ndm-1 was first identified in december 2009 in a patient hospitalized in new delhi with an infection caused by klebsiella pneumoniae.
Padhi s (2011) new delhi metallo-beta-lactamase: a weapon for the newly emerging drug-resistant bacteria indian j med sci 65: 317–320 indian j med sci 65: 317–320 woodford n, ellington mj (2007) the emergence of antibiotic resistance by mutation. New delhi metallo-beta-lactamase 1 (ndm-1) has been identified as a potential target for the treatment of multi-drug resistance bacterial infections we used molecular docking, normal md, sie, qm/mm md simulations, qm/mm gbsa binding free energy, and qm/mm gbsa alanine-scanning mutagenesis. The latest addition to this list of panic creating organisms is, bacteria encoding the gene for new delhi metallo-beta-lactamase (ndm)-1 ndm-1 is an enzyme that can hydrolyse and inactivate carbapenems, which are used as a last resort for the treatment of multiresistant bacterial infections. Multidrug-resistant klebsiella pneumoniae and escherichia coli isolates harboring new delhi metallo-β-lactamase (ndm-1) were isolated from a patient who had returned to canada from india the ndm-1 gene was found on closely related incompatibility group a/c type plasmids the occurrence of ndm-1 in north america is a major public health concern.
We characterized 9 new delhi metallo-β-lactamase–producing enterobacteriaceae (5 klebsiella pneumoniae, 2 escherichia coli, 1 enterobacter cloacae, 1 salmonella enterica serovar senftenberg) isolates identified in the united states and cultured from 8 patients in 5 states during april 2009–march 2011. New delhi metallo-β-lactmase-1 (ndm-1) has recently emerged as a global threat because of its ability to confer resistance to almost all clinically used β-lactam antibiotics, its presence within an easily transmissible plasmid bearing a number of other antibiotic resistance determinants, its carriage in a variety of enterobacteria, and its presence in both nosocomial and community-acquired. Therefore, based on cdc guidance (1), the isolate was sent to cdc for testing to determine the mechanism of antimicrobial resistance, which confirmed the presence of new delhi metallo-beta-lactamase (ndm. New delhi metallo-beta-lactamase-1 (ndm-1) is the most recently discovered transferable molecular class b beta-lactamase unlike class a, c and d beta-lacta-mases, ndm-1 has zinc ions at its active site, and it can hydrolyse all beta-lactam antimicrobials except for monobactam [1-3] moreover, most ndm-1-positive. Ndm-1 (new delhi metallo-β-lactamase) (class b) edit main article: new delhi metallo-beta-lactamase originally described from new delhi in 2009, this gene is now widespread in escherichia coli and klebsiella pneumoniae from india and pakistan.
The new delhi metallo-beta-lactamase (ndm-1) is a novel type of mbl named after the city of origin, which has been recently criticized, following a common practice with transferable mbls since vim-1 was named after verona, italy. The recently identified new delhi mbl 1 (ndm-1) is a novel member of this famil antibiotic resistance in bacterial pathogens poses a serious threat to human health and the metallo-β-lactamase (mbl) enzymes are responsible for much of this resistance. In india and pakistan and had new type of metallo beta lactamase designated as new delhi metallo-1 (ndm-1) objective : to assess the production of ndm-1 type metallo beta lactamase enzyme in enterobacteriaceae at a.
Abstract acquired carbapenemases confer extensive antibiotic resistance to enterobacteriaceae and represent a public health threat a novel acquired carbapenemase, new delhi metallo-beta-lactamase 1 (ndm-1), has recently been described in the united kingdom and sweden, mostly in patients who had received care on the indian subcontinent. Ndm - 1(new delhi metallo-betalactamase - 1) is a carbapenemase beta lactamase enzyme this enzyme is coded by blandm -1or ndm - 1 gene this gene encodes, 269 amino acids containing protein, with molecular mass of approx 275 kda [1. Ndm-1 stands for new delhi metallo-ß-lactamase-1 it was first isolated in a swedish patient of indian origin who travelled to india in 2008 what led to the emergence of ndm-1 in india is not clear. Ndm indicates new delhi metallo-β-lactamase this diagram illustrates the suspected modes of transmission of ndm-producing escherichia coli among case patients each box represents a case patient.
New-delhi-metallo-beta-lactamase (ndm-1), a new type of mbl, was first detected in two k pneumoniae and escherichia coli strains isolated from a swedish patient who was admitted to a hospital in. Ndm-1 (new delhi metallo-beta-lactamase 1), a genetic element encoding multiple-resistance genes, has been found in various enterobacteriaceae, rendering them resistant to nearly all antimicrobial. Characterization of a new metallo-beta-lactamase gene, bla(ndm-1), and a novel erythromycin esterase gene carried on a unique genetic structure in klebsiella pneumoniae sequence type 14 from india antimicrob agents chemother, 200953:5046-54.
