Antimicrobial Resistance in Salmonella Across Aquaculture, Seafood and Related Aquatic Environments: A Scoping Review With Exploratory Textual Analysis

open access: yesReviews in Aquaculture, Volume 18, Issue 2, March 2026.
This scoping review with textual analysis maps antimicrobial resistance in Salmonella across aquaculture, seafood, and related aquatic environments. Across 93 studies, recurrent MDR patterns suggest sentinel serotypes (S. Typhimurium, S. Newport) and a minimal antimicrobial susceptibility testing (AST) panel to guide matrix‐stratified One Health ...

Spectroscopic and Mechanistic Studies of Heterodimetallic Forms of Metallo-β-lactamase NDM-1 [PDF]

open access: yes, 2014
In an effort to characterize the roles of each metal ion in metallo-β-lactamase NDM-1, heterodimetallic analogues (CoCo-, ZnCo-, and CoCd-) of the enzyme were generated and characterized. UV–vis, 1H NMR, EPR, and EXAFS spectroscopies were used to confirm

Pharmacokinetics of Aztreonam–Avibactam After Single‐ and Multiple‐Dose Administration: A Phase 1, Open‐Label Study in Healthy Chinese Participants and Ethnic Comparison with Non‐Chinese Participants

open access: yesClinical Pharmacology in Drug Development, Volume 15, Issue 2, February 2026.
ABSTRACT Combined treatment with aztreonam (an established intravenous antibiotic) and avibactam (a β‐lactamase inhibitor) has the potential to address the unmet need for safe and effective agents to combat infections caused by Gram‐negative bacteria producing metallo β‐lactamases (MBLs).

Conformational Dynamics of metallo-β-lactamase CcrA during Catalysis Investigated by Using DEER Spectroscopy [PDF]

open access: yes, 2015
Previous crystallographic and mutagenesis studies have implicated the role of a position-conserved hairpin loop in the metallo-β-lactamases in substrate binding and catalysis.

Validation of Hexaplex Recombinase Polymerase Amplification Assay for the Detection of Carbapenemase Genes in Klebsiella pneumoniae Isolates From Pediatric Inpatients

open access: yesJournal of Clinical Laboratory Analysis, Volume 40, Issue 4, February 2026.
A novel hexaplex recombinase polymerase amplification (RPA) method was developed to rapidly and accurately detect five key carbapenemase genes and a Klebsiella pneumoniae‐specific target in a single reaction. This makes it an effective tool for CRKP detection in resource‐constrained environments.

The Burden of Antimicrobial‐Resistant Pseudomonas aeruginosa Isolates in Children With Cystic Fibrosis: Molecular Characterization and Genotyping Analysis

open access: yesMicrobiologyOpen, Volume 15, Issue 1, February 2026.
This study highlights the prevalence of multidrug‐ and carbapenem‐resistant Pseudomonas aeruginosa in pediatric cystic fibrosis patients, along with the presence of carbapenemase‐encoding genes and genetic profiles, suggesting clonal spread. These findings underscore the urgent need for surveillance and strategies to combat resistant strains and ...

Rapid Typing of Extended‐Spectrum β‐Lactamase (ESBL)‐ and Metallo‐β‐Lactamase (MBL)‐Producing Enterobacterales Using Fourier Transform Infrared (FT‐IR) Spectroscopy

open access: yesMicrobiologyOpen, Volume 15, Issue 1, February 2026.
Clinical isolates of Klebsiella pneumoniae and Enterobacter cloacae complex were analyzed using FT‐IR spectroscopy and genotyping methods. High concordance was observed, demonstrating the potential of FT‐IR spectroscopy as a rapid screening tool.

Crystal structures of VIM‐1 complexes explain active site heterogeneity in VIM‐class metallo‐β‐lactamases

open access: yesThe FEBS Journal, 2018
Metallo‐β‐Lactamases (MBLs) protect bacteria from almost all β‐lactam antibiotics. Verona integron‐encoded MBL (VIM) enzymes are among the most clinically important MBLs, with VIM‐1 increasing in carbapenem‐resistant Enterobacteriaceae (Escherichia coli,

Antibiotic Resistance, Biofilm Genes, and smeDEF Efflux Pump in Clinical Stenotrophomonas maltophilia Isolates From Iran

open access: yesMicrobiologyOpen, Volume 15, Issue 1, February 2026.
Iranian clinical Stenotrophomonas maltophilia isolates showed high susceptibility to trimethoprim/sulfamethoxazole, minocycline, and levofloxacin, but marked resistance to ceftazidime and ticarcillin‐clavulanate, alongside widespread biofilm production and resistance genes.

Interaction of Avibactam with Class B Metallo-β-Lactamases

open access: yesAntimicrobial Agents and Chemotherapy, 2016
β-Lactamases are the most important mechanisms of resistance to the β-lactam antibacterials. There are two mechanistic classes of β-lactamases: the serine β-lactamases (SBLs) and the zinc-dependent metallo-β-lactamases (MBLs).
