Bacterial resistance to silver in wound care.
Ionic silver exhibits antimicrobial activity against a broad range of micro-organisms. As a consequence, silver is included in many commercially available healthcare products. The use of silver is increasing rapidly in the field of wound care, and a wide variety of silver-containing dressings are now commonplace (e.g. Hydrofiber dressing, polyurethane foams and gauzes). However, concerns associ...

متن کاملSilver-Zinc Redox-Coupled Electroceutical Wound Dressing Disrupts Bacterial Biofilm
Pseudomonas aeruginosa biofilm is commonly associated with chronic wound infection. A FDA approved wireless electroceutical dressing (WED), which in the presence of conductive wound exudate gets activated to generate electric field (0.3-0.9V), was investigated for its anti-biofilm properties. Growth of pathogenic P. aeruginosa strain PAO1 in LB media was markedly arrested in the presence of the...
متن کاملRedox eustress: roles for redox-active metabolites in bacterial signaling and behavior.
SIGNIFICANCE Plant biologists and microbiologists have long discussed and debated the physiological roles of so-called "redox-active metabolites." These are natural products with unusually high redox activity that are not directly required for active growth. Generally, the biological roles of these compounds have been ascribed to interspecies competition and virulence, and they have been consid...
متن کاملBacterial silver resistance: molecular biology and uses and misuses of silver compounds.
Resistance to silver compounds as determined by bacterial plasmids and genes has been defined by molecular genetics. Silver resistance conferred by the Salmonella plasmid pMGH100 involves nine genes in three transcription units. A sensor/responder (SilRS) two-component transcriptional regulatory system governs synthesis of a periplasmic Ag(I)-binding protein (SilE) and two efflux pumps (a P-typ...
