Drug-resistant bacteria destroyed by narrow-spectrum UV light

Despite major efforts to keep operating rooms sterile, surgical wound infections remain a serious and stubborn problem, killing up to 8,200 patients a year in the U.S. A study by Columbia University Medical Center (CUMC) researchers suggests that narrow-spectrum ultraviolet (UV) light could dramatically reduce such infections without damaging human tissue. The study, conducted in tissue culture, was published in the journal PLOS ONE. Approximately 200,000 to 300,000 patients suffer surgical wound infections in the U.S...
