The aim of this study was to evaluate the ability of 0.1% thyme oil (TO), trans-cinnamaldehyde (TC), ferulic acid (FA), p-coumaric acid (p-CA), caffeic acid (CA), lavender essential oil (LO), geranium essential oil (GO) and tee tree oil (TTO) to control biofilms formed by methicillin-resistant Staphylococcus aureus (MRSA) strains. Depending on the strains, TO reduced 59.7-85% of biofilm mass, while TC 52.9-82.4% after 48 h of treatment. Reduction of metabolic activity of biofilms in ranges 79.3-86% and 85.9-88.7% was observed after 48 h of TC and TO of treatment, respectively. In the case of some strains, reduction of biofilm mass in the presence of FA, CA, GO, LO and TTO was not observed. This study showed that TO and TC might have therapeutic potential as an inhibitory agents for use in MRSA biofilm-related infections.

Poor diabetic wound healing poses a critical threat to human health. Excessive oxidative stress and increased susceptibility to bacterial infection are key issues that impede diabetic wound healing. Cerium oxide nanoparticles (CeO NPs) have attracted increasing attention because of their unique antioxidant and antimicrobial properties.

Hospital surfaces are often contaminated with multidrug-resistant pathogenic bacteria that cause healthcare-associated infections and lead to increased mortality and morbidity. There is a need for new alternative antibacterial agents to overcome antibiotic resistance. Azadirachta indica and Simmondsia chinensis have been found to possess antibacterial activity and medicinal value.

Heteroleptic coumarin-based silver(I) complexes with improved solubility profiles were synthesised using either triphenylphosphine or an -heterocyclic carbene as adduct ligands, and were fully characterised using IR and NMR spectroscopy, elemental analysis, and, where possible, X-ray crystallography. The triphenylphosphine adducts formed well-resolved structures, where the oxyacetate ligands asymmetrically chelated the silver(I) ion in a bidentate chelating mode, and the silver(I) ion was also bound to two triphenylphosphine ligands. The solubility profile and photostability of the adducts were considerably improved compared to those of previously isolated simple coumarin silver(I) complexes.

Biofilm formation on prostheses and implanted devices can lead to serious complications and increased healthcare expenditures. Once formed, biofilm management is difficult and may involve a long course of antibiotics, additional surgery, and, occasionally, implant removal. This study evaluated the antibacterial properties of medical-grade silicone samples integrated with novel, non-leaching, antibacterial, quaternary ammonium silica (QASi) particles.

: In environments with high-frequency contact surfaces, drug-resistant bacteria, such as carbapenem-resistant and methicillin-resistant (MRSA), can survive for extended periods, contributing to healthcare-associated infections. Ultraviolet (UV)-C irradiation often fails to adequately disinfect shadowed areas, leading to a persistent contamination risk. We evaluated the effectiveness of using a UV-C containment unit (UVCCU) in conjunction with UV-C irradiation to improve the sterilization effects on both direct and indirect surfaces, including shadowed areas, and to assess the leakage of UV radiation to the surroundings.
