Copper’s Efficacy Demonstrated Against Highly-resistant Bacteria

Antimicrobial copper under a microscope

Research presented at the FIS/HIS International Conference at the end of 2016 demonstrates the efficacy of copper and copper alloys against coagulase-negative Staphylococci (CoNS)— the predominant pathogens in Polish hospital environments, with highly antibiotic-resistant strains.

24 January 2017

Researchers from Jagiellonian University Medical College isolated CoNS from touch surfaces in Polish hospitals, assessed survival of these bacteria on pure copper, brass and bronze, using stainless steel as a negative control. Pure copper eliminated the bacteria fastest, with comparable speed from the bronze and rapid efficacy on brass.

The researchers concluded: ‘copper alloy materials exhibit strong antimicrobial properties against the study strains… The use of equipment made of materials with antimicrobial properties can help limit the spread of antibiotic resistance genes in the hospital environment.’

Copper and copper alloys are engineering materials that are durable, colourful and recyclable and are widely available in various product forms suitable for a range of manufacturing purposes. Copper and its alloys offer a suite of materials for designers of functional, sustainable and cost-effective products.

Copper and certain copper alloys have intrinsic antimicrobial properties (so-called ‘Antimicrobial Copper’) and products made from these materials have an additional, secondary benefit of contributing to hygienic design. Products made from Antimicrobial Copper are a supplement to, not a substitute for standard infection control practices. It is essential that current hygiene practices are continued, including those related to the cleaning and disinfection of environmental surfaces.
