In 20 patients undergoing cataract extraction, we measured pefloxacin concentrations in the eye. After a 1 h infusion of pefloxacin 400 mg iv, the mean pefloxacin concentrations 2, 6, 12 and 24 h post-infusion were 0.75, 1.45, 1.04 and 0.86 mg/l, respectively. The simultaneous mean pefloxacin concentrations in the lens were 0.09, 0.20, 0.26 and 0.43 mg/l, respectively. The adequate penetration of pefloxacin into uninfected aqueous humour and lens suggests that this antibiotic may be effective in the treatment of certain bacterial endophthalmic infections.

The global spread of antimicrobial resistance is one of the most significant challenges of the 21st century. The waterfowl sector is an economically decisive part of the poultry industry, yet it remains under-researched, and its antibiotic usage is less monitored. Our study aimed to determine the antimicrobial susceptibility of avian pathogenic strains, which are still prevalent in ducks and geese, against antibiotics critical for both animal and human health, and to compare these findings with human resistance data.

Antimicrobial resistance poses a global public health threat, compelling the search for alternative treatments, especially in resource-limited settings. The increasing ineffectiveness of traditional antibiotics has intensified the need to explore medicinal plants as viable therapeutic options. This study sought to compare the efficacy of certain medicinal plants used in Owerri, Nigeria, for treating pathogenic bacteria against traditional commercial antibiotics.

A new nanopalladium surface molecularly imprinted covalent organic framework (MICOF) catalytic probe (Pd@TpPa) for enrofloxacin (ENR) was synthesized by molecular imprinting technology, using 1,3,5-triformylphloroglucinol (Tp) and p-phenylenediamine (Pa) as monomers, ENR as the template molecule, and palladium nanoparticles (PdNP) as the core of nanocatalytic probe. This nanoprobe not only specifically recognizes ENR but also catalyzes the cupric tartrate-glucose (GL) indicator reaction. The amino groups in TpPa replace the tartrate ions, forming a new complex with Cu.

During the water treatment process, chlorination and ultraviolet (UV) sterilization can modify microplastics (MPs) and alter their physicochemical properties, causing various changes between MPs and other pollutants. In this study, the impact of chlorination and UV modification on the physicochemical properties of polystyrene (PS) and polyvinyl chloride (PVC) were investigated, and the adsorption behavior of pefloxacin (PEF) before and after modification was examined. The effect of pH, ionic strength, dissolved organic matter, heavy metal ions and other water environmental conditions on adsorption behavior was revealed.

Microplastics (MPs) in sludge can affect the ability of biochar-activated peroxymonosulfate (PMS) to degrade antibiotics. In this work, biochar was prepared by mixing sludge and polystyrene (PS) through hydrothermal carbonization (HTC) and high-temperature pyrolysis processes. The resulting biochar was used to activate PMS to degrade ofloxacin (OFX), levofloxacin (LEV), and pefloxacin (PFX).
