Science Friday: Warding off Staph Infections with good hygiene, and yes ... SILVER

Football Frenzy: Dangers in the Locker Room

Careful Hygiene Can Ward Off Staph Infections
    November 1, 2006 — Drug-resistant staph infections such as methicillin-resistant Staphylococcus aureus have become more common outside prisons and hospitals, and have been known to spread among athletes in the locker room. Athletes can develop aggressive skin infections when small cuts or scratches come into contact with MRSA through contaminated equipments, clothing, or towels. Preventative measures, such as ultraviolet light filters in the locker room Jacuzzi, and adjustments in the players' behaviors are crucial steps to preventing the spread of MRSA.

Killing Germs

In Hospitals, Air Ducts with Silver-Based Coating Stay Germ-Free

    September 1, 2005 — Preventing hospital infections -- from such stubborn bugs as Staphylococcus aureus -- could get a little easier with a new non-toxic, silver-based material. Used in coating, it helps keep hospital air ducts bacterium- and fungus-free. The material is also used in a number of products including athletic footwear, door hardware, pens and business supplies.

    DUARTE, Calif.--For more than 6,000 years, humans have used silver to fight germs, also known as microbes. Now, some hospitals are using a silver compound to reduce hospital infections.

    You can't see them, but millions of microorganisms are living quietly among us, in places where we least expect them.

    Cancer patient Steve Measer worries about germs a lot. "In the last two months I have been in three separate hospitals." But at the Helford Clinical Research Hospital at City of Hope in Duarte, Calif., where he is receiving treatment, microbes are hard to find.

    Dr. James Miser, Chief Executive Officer at City of Hope National Medical Center, says, "The room which we are currently standing is as free of germs as medically possible in a hospital."

    This is possible because the ducts delivering air to patients' rooms are coated with a silver-based anti-microbial compound called AgION. It can kill bacteria, viruses and fungus. Jeffrey Trogolo, Chief Technology Officer at AgION Technologies, Inc. in Wakefield, Mass., says, "When the conditions are right, it turns on, and that's where the silver comes out."

    Agion technologies is using silver, a centuries-old germ killer, in a unique compound to coat surfaces and instruments that could spread disease. When bacteria are detected, the compound releases silver ions to the surface, killing existing microbes and any new ones that come along. "We have virtually no organisms grown," Dr. Miser says.

    It's potent enough to kill germs, but is safe to use on virtually any surface. Trogolo says, "It's less toxic than table salt and less irritating than talcum powder. Ultimately we hope this will result in less infections and actually better outcomes for the patients."

    The silver compound can also kill germs in your kitchen, on shopping cart handles, even in your sneakers. It's already used in a number of products including athletic footwear, door hardware, pens and business supplies.
