Molecular Characterization of AmpC β-lactamases in Enterobacteriaceae

Journal of Pure and Applied Microbiology, 2022
AmpC β-lactamases are enzymes that are resistant to β-lactams, such as penicillin and cephalosporin, but not cefoxitin and cefotetan. This study was conducted to characterize AmpC β-lactamases in Enterobacteriaceae.

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.

The Role of Short Journey Transportation in the Spreading of Swine Pathogens and Antimicrobial‐Resistant Bacteria

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
The transport of live pigs poses a risk to on‐farm biosecurity. Trucks can carry pathogens with significant economic and health impacts, including antimicrobial‐resistant (AMR) bacteria. This study aimed to investigate the microbiological contamination of trucks before and after loading, focusing on AMR bacteria and other major pathogens transmissible ...
