bZIP63.5 Regulates a Zinc‐Finger Mediated Detoxification Network in Trichoderma Harzianum for Enhanced Biocontrol of Alternaria alternata

Microbial Biotechnology, Volume 19, Issue 3, March 2026.
The bZIP63.5 transcription factor, activated by Alternaria alternata stress, directly upregulates zinc‐finger transcription factors (Zn2CyS6 and C2H2 types), which in turn enhance the expression of downstream detoxification and defence‐related genes, collectively improving the biocontrol efficacy of Trichoderma harzianum.

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

Reviews 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 ...

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

Nature 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 ...

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

Clinical 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).

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

Journal 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.

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

SRM 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

Nature 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 ...

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

MicrobiologyOpen, 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 ...
