Effect of a glyphosate-containing herbicide on Escherichia coli and Salmonella Ser. Typhimurium in an in vitro rumen simulation system [PDF]

, 2019
Glyphosate (N-(phosphonomethyl)glycine) is the most-used herbicide worldwide. Many studies in the past have shown that residues of the herbicide can be found in many cultivated plants, including those used as livestock feed.

Medical Fabrics with Non‐Antibiotic, Supramolecular Antimicrobial Coatings: A Preventive Approach to Combat Biofilm Formation and Bacterial Dissemination

Advanced Healthcare Materials, EarlyView.
The study presents an antibiotic‐free strategy using medical fabrics coated with supramolecular assemblies of polyarginine and hyaluronic acid. These coatings showed strong antimicrobial and anti‐biofilm activity in vitro and in vivo, achieving major bacterial load reductions, including against MRSA.

High sporulation and overexpression of virulence factors in biofilms and reduced susceptibility to vancomycin and linezolid in recurrent Clostridium [Clostridioides] difficile infection isolates [PDF]

, 2019
Clostridium [Clostridioides] difficile infection (CDI) is one of the leading causes of diarrhea associated with medical care worldwide, and up to 60% of patients with CDI can develop a recurrent infection (R-CDI). A multi-species microbiota biofilm model

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

Advanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

Staphylococcal skin infection isolates from dogs without recent antibiotic exposure are 100% susceptible to clindamycin

Frontiers in Veterinary Science
The objective of this study was to create an antibiogram representative of bacterial skin infections in canine patients that would typically be treated empirically, i.e., without risk factors for antibiotic resistance, such as a history of recent ...

Injectable Stimuli‐Responsive Amphiphilic Hydrogel for Rapid Hemostasis, Robust Tissue Adhesion, and Controlled Drug Delivery in Trauma and Surgical Care

Advanced Healthcare Materials, EarlyView.
Fast‐acting hydrogel seals bleeding wounds as the illustrated injectable, pH‐responsive network rapidly gels in situ to stop hemorrhage, adhere strongly to wet tissue, and release antibiotics in a controlled, pH‐dependent manner. The material withstands high pressures, shows excellent biocompatibility, and degrades safely, offering a versatile platform

Results of bacterial cultivation are infrequently utilized in the treatment of patients hospitalized with severe odontogenic infections – a retrospective cohort study

Journal of Oral Microbiology
Background Patients hospitalized with severe odontogenic infections (SOI) receive empiric intravenous antibiotics. Microbiological cultivation and antibiotic susceptibility testing are commonly performed, although the clinical value is debated.Objective ...

Biomimetic Copper Nanoparticles Coated with ACE2‐Overexpressing Membranes for Selective SARS‐CoV‐2 Neutralization and Disinfection

Advanced Healthcare Materials, EarlyView.
By fusing ACE2‐overexpressing membrane‐integrated liposome (MIL) with copper nanoparticles, the biomimetic Cu@MIL nanostructures were created that directly hijack the SARS‐CoV‐2 entry pathway. These particles combine potent virus‐targeting precision with intrinsic antiviral activity, achieving rapid neutralization and disinfection.
