Highlight
- •Extended-spectrum beta-lactamase (ESBL) infections can cause life-threatening disease.
- •The bactericidal effect of far- ultraviolet C (far-UVC) on the ESBL-producing Escherichia coli (E. coli) was shown.
- •Irradiation with far- UVC may be effective in preventing infection by ESBL-producing E. coli.
Because extended-spectrum beta-lactamase (ESBL) infections can cause life-threatening
disease and effective treatments need to be developed, we examined the bactericidal
effect of far-ultraviolet C (far-UVC) light therapy on ESBL-producing Escherichia coli (E. coli). The bactericidal effect on 2 types of ESBL-producing E. coli was the same as that on the wild strain although the results of drug resistance tests
varied among these strains. We believe that irradiation with far-UVC is effective
in preventing infection by ESBL-producing E. coli in health care settings.
