The MRSA “superbug” is a virulent bacterium resistant to broad spectrum antibiotics and, therefore, very difficult to treat. It is a common source of infection in hospitals and is increasingly being found in the community as well. According to the CDC, MRSA can cause serious, potentially life-threatening infections.
Nevertheless, studies at the University of Southampton, UK, and tests subsequently performed for the EPA show that copper-base alloys containing 65% or more copper are effective against:
- Methicillin-resistant Staphylococcus aureus (MRSA)
- Staphylococcus aureus
Vancomycin-resistant Enterococcus faecalis (VRE)
- Enterobacter aerogenes
- Escherichia coli O157:H7
- Pseudomonas aeruginosa.
These bacteria are considered to be representative of the most dangerous pathogens capable of causing severe and often fatal infections.
The EPA studies show that on copper alloy surfaces, greater than 99.9% of MRSA, as well as the other bacteria shown above, are killed within two hours at room temperature.
