Evaluation of FilmArray Multiplex PCR Test Results in Bloodstream Infections in Oncological Patients

Journal of Clinical Laboratory Analysis, Volume 40, Issue 9, May 2026.
In this study conducted at an oncology hospital, BCID2 panel results for the rapid identification of microorganisms and resistance genes in positive blood culture samples were compared with conventional culture methods. The BCID2 panel provided faster results and showed a high correlation with traditional methods.

Genomic Insights Into Carbapenem‐Resistant Klebsiella pneumoniae in Pediatric Bloodstream Infections in Zhejiang, China (2019–2024)

Journal of Clinical Laboratory Analysis, Volume 40, Issue 10, May 2026.
The primary mechanism of carbapenem resistance identified in pediatric CRKP‐BSI strains was the production of Class B metalloenzymes. We report, for the first time, an outbreak of bloodstream infections in a neonatal ward caused by the dissemination of NDM‐1‐producing ST25 K. pneumoniae.

Resistance of Gram-Negative Bacteria to Cefepime-Enmetazobactam: A Systematic Review

Pathogens
Cefepime-enmetazobactam is a novel β-lactam/β-lactamase inhibitor combination showing good activity against multidrug-resistant (MDR) Gram-negative bacteria producing a variety of β-lactamases.

Approachable Synthetic Methodologies for Second-Generation β-Lactamase Inhibitors: A Review

Pharmaceuticals
Some antibiotics that are frequently employed are β-lactams. In light of the hydrolytic process of β-lactamase, found in Gram-negative bacteria, inhibitors of β-lactamase (BLIs) have been produced.

Structure of apo- and monometalated forms of NDM-1--a highly potent carbapenem-hydrolyzing metallo-β-lactamase.

PLoS ONE, 2011
The New Delhi Metallo-β-lactamase (NDM-1) gene makes multiple pathogenic microorganisms resistant to all known β-lactam antibiotics. The rapid emergence of NDM-1 has been linked to mobile plasmids that move between different strains resulting in world ...

Evolution of Metallo-β-lactamases: Trends Revealed by Natural Diversity and in vitro Evolution

Antibiotics, 2014
The production of β-lactamase enzymes is one of the most distributed resistance mechanisms towards β-lactam antibiotics. Metallo-β-lactamases constitute a worrisome group of these kinds of enzymes, since they present a broad spectrum profile, being able

A DNA aptamer reveals an allosteric site for inhibition in metallo-β-lactamases.

PLoS ONE, 2019
The hydrolysis of β-lactam antibiotics by β-lactamase enzymes is the most prominent antibiotic resistance mechanism for many pathogenic bacteria. Out of this broad class of enzymes, metallo-β-lactamases are of special clinical interest because of their ...
