Biomaterial modification of urinary catheters with antimicrobials to give long-term broadspectrum antibiofilm activity
Leanne E. Fisher,Andrew L. Hook,Waheed Ashraf,Anfal Yousef,David A. Barrett,David J. Scurr,Xinyong Chen,Emily F. Smith,Michael W. Fay,Christopher D. J. Parmenter,Richard Parkinson,Roger Bayston +11 more
TL;DR: The antimicrobial catheter offers for the first time a means of reducing infection and its complications in long-term urinary catheter users.

Biofilm formation by Propionibacterium acnes on biomaterials in vitro and in vivo: impact on diagnosis and treatment.
Roger Bayston,Waheed Ashraf,Robert M. Barker-Davies,Emily Tucker,Rhys G.E. Clement,Juliet Clayton,Brian J. C. Freeman,Bryar Nuradeen +7 more
TL;DR: Biofilm development by P. acnes is demonstrated, including production of exopolymer similar in appearance to the polysaccharide intercellular adhesin of Staphylococcus epidermidis, which explains the difficulties encountered in clinical management of such infections.

Mode of action of an antimicrobial biomaterial for use in hydrocephalus shunts
TL;DR: Impregnated antimicrobial material is likely to reduce shunt infection rates significantly without the risks and side effects of systemic antibiotics.

A biodegradable antibiotic-impregnated scaffold to prevent osteomyelitis in a contaminated in vivo bone defect model.
Jane McLaren,Lisa J. White,Helen C. Cox,Waheed Ashraf,Cheryl V. Rahman,Gordon Blunn,Allen E. Goodship,Robin A. Quirk,Kevin M. Shakesheff,Roger Bayston,Brigitte E. Scammell +10 more
TL;DR: A new injectable formulation that simultaneously hardens in vivo to form a porous scaffold for bone repair and delivers antibiotics at high concentrations to the local site of infection is investigated, which might reduce the need for systemic antibiotics.
Triclosan resistance in methicillin-resistant Staphylococcus aureus expressed as small colony variants: a novel mode of evasion of susceptibility to antiseptics
TL;DR: Prolonged exposure of MRSA to triclosan-impregnated silicone, as in 'antimicrobial' plastics or catheters, resulted in the induction of SCV status and tric Losan resistance, which has implications for industrial, medical and domestic use of polymers containing tricrosan.
