Klebsiella pneumoniae is a significant nosocomial pathogen that has developed resistance to multiple antibiotics, often forming biofilms enhance its virulence. This study investigated the efficacy of novel nanoformulation, AgNPs@chitosan-NaF, in combating K. biofilms. Antimicrobial susceptibility testing was performed assess antibiotic profile isolates. The antibiofilm activity AgNPs@chitosan-NaF evaluated using crystal violet staining and scanning electron microscopy. underlying mechanisms action were through gene expression analysis. majority isolates exhibited high levels multidrug resistance. demonstrated superior biofilm inhibition compared AgNPs@chitosan, significantly reducing biomass disrupting architecture at MICs ranging from 0.125 1 μg/mL. Mechanistic studies revealed nanoformulation downregulated key biofilm-associated genes, including treC, fimA, mrkA, ecpA. While concentration-dependent cytotoxic effect on both normal cancer cell lines, minimal cytotoxicity observed concentrations below 31.25 highlights synergistic silver nanoparticles, chitosan, sodium fluoride emerges as promising therapeutic strategy address challenge multidrug-resistant bacterial infections.

This work successfully synthesized green zinc oxide nanoparticles using extracts from strawberry guava leaves (Psidium cattleianum Sabine). Additionally, the reducing effect of antioxidant obtained through traditional techniques, such as infusion and maceration, was studied compared against an emerging unconventional technology like ultrasound assisted extraction. Regarding physical chemical characteristics, it found that all three systems were confined within a wavelength range 357 to 370 nm (UV-vis) sizes 60 140 for ultrasound-assisted (SEM), corroborated with DLS (134 ± nm). Through X-ray diffraction, hexagonal wurtzite structure elucidated, observed favored higher percentage crystallinity (98%) (84%) maceration (72%). could be correlated different functional groups via FTIR thermal events associated thermogravimetric curves, where total biomass weight loss lower extract (6.25%), followed by (15.55%) (18.01%) extracts.

The global rise in antimicrobial resistance, particularly among ESKAPE pathogens, has intensified the demand for alternative therapeutic strategies. Silver nanoparticles (AgNPs) have exhibited broad-spectrum activity and represent a promising approach to combat multidrug-resistant infections. This study aimed synthesize functionalize AgNPs using various polymeric agents—ethylene glycol (EG), polyethylene (PEG), polyvinylpyrrolidone (PVP), their combinations—and evaluate antibiofilm efficacy against clinically relevant bacterial strains. were synthesized via chemical reduction functionalized as Ag@EG, Ag@PEG, Ag@EG/PVP, Ag@PEG/PVP. A total of 68 clinical isolates—including Staphylococcus aureus, epidermidis, lugdunensis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa—were tested. Antimicrobial susceptibility was assessed disc diffusion broth microdilution assays, while evaluated crystal violet method. Among all tested formulations, Ag@EG/PVP highest activity, with notably low minimum inhibitory concentrations (MIC50) biofilm eradication (MBEC50) Ps. aeruginosa K. pneumoniae. In contrast, PEG or EG alone showed limited efficacy. Biofilm-forming isolates, spp., required higher inhibition. These results highlight critical role functionalization modulating properties AgNPs, demonstrating potent both planktonic biofilm-associated bacteria. Overall, this supports further developing AgNPs-based formulations adjuncts alternatives conventional antibiotics, managing biofilm-related Future research should focus on formulation optimization, safety assessment, translational potential.
