Methicillin-Resistant Staphylococcus aureus, often referred to as
MRSA, is a type of staphylococcus
bacteria that does not respond to many
antibiotics. MRSA infection is spread from person to person through casual contact and by contaminated objects. A person with a weak immune system is easily susceptible to this
bacterial infection. MSRA can become serious in a short amount of time.
In February 2009 Chukuka S. Enwemeka, PhD, and colleagues at New York Institute of Technology discovered that MRSA dies when exposed to blue light. The team used a special LED device that emits blue light that is not part of the ultraviolet spectrum in order to make it safe for human exposure. Relatively low doses were able to kill at least 30 percent of MRSA is laboratory cultures. It is currently not known how blue light has the ability to kill MRSA or if the bacteria is able to build up a resistance to it.[WebMD: Blue Light Kills MRSA (February 4, 2009)]
