Detection of metallo-β-lactamases-encoding genes among clinical isolates of Pseudomonas aeruginosa in a tertiary care hospital, Kathmandu, Nepal

open access: yesBMC Research Notes, 2017
Objectives This study was carried out to determine the prevalence of metallo-β-lactamases (MBLs) producing Pseudomonas aeruginosa in imipenem-nonsusceptible isolates and to detect MBL-encoding genes among MBLs-positive isolates.

OXA-carbapenemases present in clinical acinetobacter baumannii-calcoaceticus complex isolates from patients in kurdistan region, Iraq [PDF]

open access: yes, 2016
In addition to intrinsic resistance in Acinetobacter baumannii, many different types of acquired resistance mechanisms have been reported, including the presence of VIM and IMP metallo β-lactamases and also of blaOXA-23-like and blaOXA-58-like enzymes ...

Bismuth antimicrobial drugs serve as broad-spectrum metallo-β-lactamase inhibitors

open access: yesNature Communications, 2018
Metallo-β-lactamases (MBL) are zinc containing enzymes that cause resistance to β-lactam antibiotics. Here the authors show that the anti-Helicobacter pylori drug colloidal bismuth subcitrate inhibits MBLs by displacing the zinc ions with Bi(III), which ...

Detection of VIM-1 and IMP-1 genes in Klebsiella pneumoniae and relationship with biofilm formation [PDF]

open access: yes, 2018
Klebsiella pneumoniae is an important human pathogen that is considered in recent years due to nosocomial infections resistant to treatment as well as the ability to form biofilms particularly in patients with urinary tract infection in ICU or hospital ...

Cloning, Expression And Characterization Of Ahlinactivating aiiA Gene Homologue In Escherichia coli [PDF]

open access: yes, 2014
Cell-to-cell communication pathway of single-celled microbes is usually coordinated by quorum sensing (QS) system mediated by signal molecules. This cell density-dependent system plays a vital role in functional coordination of most pathogenic ...

"Golden Era of Antibiotics" - Coming to an end !!!

open access: yesSRM Journal of Research in Dental Sciences, 2012
Resistance to antibiotics is increasing at an alarming rate. This is due to superbugs, producing heterogenous groups of enzymes, β-lactamases which inactivate β-lactam antibiotics and others as well.

The mechanism of NDM-1-catalyzed carbapenem hydrolysis is distinct from that of penicillin or cephalosporin hydrolysis

open access: yesNature Communications, 2017
New Delhi metallo-β-lactamases (NDMs) hydrolyze almost all β-lactam antibiotics and pose a major public health threat. Here, the authors study the mechanism of NDM-1 catalyzed carbapenem hydrolysis and present the crystal structures of the enzyme ...

Reappraisal of hospital-acquired pneumonia mortality in the era of metallo-β-lactamase-mediated multidrug resistance: a prospective observational study [PDF]

open access: yes, 2006
Introduction Hospital-acquired pneumonia (HAP) due to Pseudomonas aeruginosa is associated with high mortality rates. The metallo-β-lactamases (MBLs) are emerging enzymes that hydrolyze virtually all β-lactams. We aimed to assess P.

Metallo-β-Lactamase Inhibitors Inspired on Snapshots from the Catalytic Mechanism

open access: yesBiomolecules, 2020
β-Lactam antibiotics are the most widely prescribed antibacterial drugs due to their low toxicity and broad spectrum. Their action is counteracted by different resistance mechanisms developed by bacteria.
