Formulation, Characterisation, and Biocompatibility Assessment of Rifampicin-Loaded Poly(d,l-lactide-co-glycolide) Composites for Local Treatment of Orthopaedic and Wound Infections.

The escalating challenge of antimicrobial resistance (AMR) necessitates the development of targeted antibiotic delivery platforms, minimising systemic administration. Polymer-based drug delivery emerges as a promising solution, ensuring sustained release and prolonged efficacy of bioactive compounds, ensuring long-term efficacy. This study focuses on encapsulating rifampicin (RIF), a key antibiotic for orthopaedic and wound-related infections, within Poly(d,l-lactide-co-glycolide) (PLGA), a biodegradable polymer, through solvent casting, to formulate a PLGA-RIF composite membrane.

Photophysical, thermal and imaging studies on vancomycin functional branched poly(-isopropyl acrylamide) of differing degrees of branching containing nile red for detection of Gram-positive bacteria.

Highly branched poly(-isopropyl acrylamide) additives chain end functionalised with vancomycin have been designed to agglutinate and report on targetted Gram-positive strains of bacteria (). These branched systems selectively desolvate with temperature or binding interactions depending on their chain architecture. We have prepared samples with three different degrees of branching which have incorporated Nile red acrylate as a low concentration of co-monomer to report upon their solution properties.

Metal-Organic Frameworks and Their Biodegradable Composites for Controlled Delivery of Antimicrobial Drugs.

Antimicrobial resistance (AMR) is a growing global crisis with an increasing number of untreatable or exceedingly difficult-to-treat bacterial infections, due to their growing resistance to existing drugs. It is predicted that AMR will be the leading cause of death by 2050. In addition to ongoing efforts on preventive strategies and infection control, there is ongoing research towards the development of novel vaccines, antimicrobial agents, and optimised diagnostic practices to address AMR.

Draft Genome Sequence of a Multiple Antibiotic Resistant Staphylococcus aureus NCTC 6571-UB Laboratory Strain.

We report the draft genome sequence of the laboratory strain Staphylococcus aureus NCTC 6571-UB, a strain that was derived from S. aureus NCTC 6571. This strain was selected for sequencing in order to provide information on the genome dynamics and the acquired resistance genes for penicillin G, trimethoprim, and sulfamethoxazole resistance.

Draft Genome Sequence of the Multiple Antibiotic Resistant Pseudomonas aeruginosa PAO1-UB Subline.

We report the draft genome sequence and antibiotic susceptibility of Pseudomonas aeruginosa strain PAO1-UB, a subline of the common reference strain PAO1. This strain was sequenced in order to provide information on the genome dynamics of PAO1 sublines and their genes conferring resistance to multiple antibiotics.
