Scientists from the Center for Radiological Research at Columbia University have found that narrow-wavelength ultraviolet (UV) light kills methicillin-resistant Staphylococcus aureus (MRSA) bacteria in mice, according to a study published online June 8 in PLOS One.
The finding suggests a potentially safe and cost-effective way to reduce surgical site infections, the researchers wrote.
Senior author David Brenner, PhD, and colleagues found that a particular wavelength of UV light called "far-UVC" is effective in killing the bacteria and does not damage exposed skin (PLOS One, June 8, 2016).
The study results offer a practical way to significantly reduce surgical site infection rates without risk to the health and safety of patients and medical personnel, Brenner said in a statement released by Columbia University.
