Overview Metallo-β-lactamase inhibitors: Promise for the future?
Carbapenem resistance continues to erode the effectiveness of antibiotics such as imipenem and meropenem in the clinic. Resistance mechanisms can include interplay between porin loss (membrane permeability), mutation of penicillin binding proteins necessary for cell division, and expression of class A, B and D β-lactamases. Bacterial resistance to β-lactams such as penicillin or amoxicillin has...
متن کاملOligopeptides as full-length New Delhi metallo-β-lactamase-1 (NDM-1) inhibitors
'Superbug' bacteria producing NDM-1 enzyme causing wide public concern were first detected in a patient who visited India in 2008. It's an effective approach to combining β-lactam antibiotics with NDM-1 inhibitor for treating NDM-1 producing strain infection. In our research, we designed ten oligopeptides, tested IC50 values against NDM-1 enzyme, determined the MIC values of synergistic antibac...
متن کاملNew 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 کاملLight as a Broad-Spectrum Antimicrobial
Antimicrobial resistance is a significant and growing concern. To continue to treat even simple infections, there is a pressing need for new alternative and complementary approaches to antimicrobial therapy. One possible addition to the current range of treatments is the use of narrow-wavelength light as an antimicrobial, which has been shown to eliminate a range of common pathogens. Much progr...
متن کاملPrevalence of Extended-Spectrum and Metallo β-Lactamase Production in AmpC β-Lactamase Producing Pseudomonas aeruginosa Isolates From Burns
BACKGROUND Pseudomonas aeruginosa is one of the most common causes of nosocomial infections. Resistance of P. aeruginosa to β-lactam antibiotics may be the result of acquired resistance through mutation and over production of various antibiotic inactivating enzymes. This research aimed to determine the prevalence of extended-spectrum β-lactamases (ESBL) and metallo β-lactamase (MBL) production ...
