Integrated metagenomic, culture-based, and whole genome sequencing analyses of antimicrobial resistance in wastewater and drinking water treatment plants in Barcelona, Spain.

The misuse and overuse of antimicrobials drive the emergence of antimicrobial resistance (AMR), a critical global health concern. While wastewater treatment plants (WWTPs) are essential for removing microorganisms and contaminants, they also serve as hotspots for antibiotic-resistant bacteria (ARB) and antimicrobial resistance genes (ARGs), facilitating their persistence and dissemination. This study investigated AMR in two WWTPs and one drinking water treatment plant (DWTP) in the Baix Llobregat area of Barcelona, Spain.

Prevalence of bacterial contamination on wild meat processing and cooking surfaces in rural Cameroon.

The transmission of food-borne pathogens from wildlife to humans presents a significant public health challenge. The recent COVID-19 pandemic has highlighted the critical need to enhance our understanding of wild animals' role in transmitting infectious diseases. The handling and consumption of wild meat carry inherent risks of contracting foodborne illnesses.

Solvent Effect on Antimicrobial Hydrophilic Xerogel Coating of Medicinal Leathers in Simulated Industrial Finishing Process.

The hydrophilic character and the protection against pathogen proliferation are the most pivotal characteristics of leathers intended for medical purposes. To achieve these goals, dispersions of TiO particles incorporating three different formulations of biomimetically synthesized silica xerogels were tested. Emphasis has been given to the role of single and dual solvents employed.

Hybrid Silica Xerogel and Titania/Silica Xerogel Dispersions Reinforcing Hydrophilicity and Antimicrobial Resistance of Leathers.

Four leather substrates from different animals were treated by dispersions containing hydrophilic composite silica-hyperbranched poly(ethylene imine) xerogels. Antimicrobial activity was introduced by incorporating silver nanoparticles and/or benzalkonium chloride. The gel precursor solutions were also infused before gelation to titanium oxide powders typically employed for induction of self-cleaning properties.
