Objective: The difficulty of establishing slow release at intestinal infection sites, weak antibacterial effects, as well as the limited broad use of florfenicol oral formulations are the main targets of the current study. Novel hydrogels derived from sodium alginate were developed using a complexation form for florfenicol delivery to achieve slow release at the site of intestinal infection and enhance its antibacterial activity against .
Methods: The optimal formulation, physicochemical properties, stability, pH-responsive performance, antibacterial activity, and in vitro biosafety of the florfenicol hydrogels have been studied systematically.

Bacterial infections significantly threaten human health, leading to severe diseases and complications across multiple systems and organs. Antibiotics remain the primary treatment strategy for these infections. However, the growing resistance of bacteria to conventional antibiotics underscores the urgent need for safe and effective alternative treatments.

Plant-derived foods are potential vehicles for microbial antibiotic resistance genes (ARGs), which can be transferred to the human microbiome if consumed raw or minimally processed. The aim of this study was to determine the prevalence and the amount of clinically relevant ARGs and mobile genetic elements (MGEs) in differently processed smoothies (freshly prepared, cold-pressed, pasteurized and high-pressure processed) and fresh produce samples (organically and conventionally cultivated) to assess potential health hazards associated with their consumption. The MGE and the class 1 integron-integrase gene were detected by probe-based qPCR in concentrations up to 10 copies/mL in all smoothies, lettuce, carrots and a single tomato sample.

Article Synopsis
- The study focused on creating and testing Cobalt-doped zinc oxide nanoparticles as a photocatalyst for degrading the antibiotic ciprofloxacin (CIPF) under visible LED light.
- It was found that 10% Cobalt-doped ZnO nanoparticles were the most effective, achieving over 99% degradation of CIPF in just 90 minutes, and maintained their efficiency across three cycles of use.
- The research also optimized the conditions for maximum degradation efficiency using statistical methods and simulated data using Artificial Neural Networks, achieving a strong correlation for the model’s accuracy.
