Novel Class 1 Integrons in Multi-drug Resistant Isolates from Eastern China [PDF]

Indian Journal of Microbiology, 2013
Integrons are mobile genetic elements able to capture, express and excise resistance genes, playing an important role in the spread of bacterial resistance. The present study was to investigate the occurrence and diversity of integrons in 120 clinical multi-drug resistant Gram-negative isolates from eastern China.

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 ...

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.

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

MicrobiologyOpen, 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.

The Evolution of Class 1 Integrons and the Rise of Antibiotic Resistance [PDF]

Journal of Bacteriology, 2008
ABSTRACTClass 1 integrons are central players in the worldwide problem of antibiotic resistance, because they can capture and express diverse resistance genes. In addition, they are often embedded in promiscuous plasmids and transposons, facilitating their lateral transfer into a wide range of pathogens.

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

MicrobiologyOpen, 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.

Class 1 and class 2 integrons in avian pathogenic Escherichia coli from poultry in Italy

Poultry Science, 2015
The aim of this study was to investigate the occurrence of class 1 and 2 integrons in avian pathogenic Escherichia coli (APEC) from poultry in northern Italy. Strains were tested for phenotypic resistance to aminoglycosides and sulphonamides, and the association between the presence of integrons and the resistance to these antimicrobials was evaluated.

Reversing Antibiotic Resistance: Strategies From Adjuvants to Innovative Therapeutics

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Molecular reversal strategies against antibiotic resistance act through three mechanisms: inhibiting resistance gene function, blocking horizontal gene transfer, and modulating host defense. Emerging technologies, such as CRISPR‐Cas gene editing, photodynamic therapy, nanotechnology, and ecological competition, further strengthen these approaches ...

Antibacterial Activity of Estragole From Ocimum tenuiflorum, and Tagetes lucida and Synergistic Effect With Meropenem and Tobramycin Against Multidrug‐ and Extensively Drug‐Resistant (MDR‐XDR) Gram‐Negative Bacteria

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
This study reveals estragole's bactericidal activity against MDR/XDR Gram‐negative pathogens. Synergy with meropenem and tobramycin was observed in > 88% of strains, reducing antibiotic MICs up to 16‐fold. Estragole represents a promising therapeutic adjuvant to enhance antibiotic efficacy and combat antimicrobial resistance.
