ScienceDaily (Jan. 31, 2009) — Two common strains of methicillin-resistant Staphylococcus aureus, commonly known as MRSA, were virtually eradicated in the laboratory by exposing them to a wavelength of blue light, in a process called photo-irradiation.
Antibiotic-resistant bacterial infections represent an important and increasing public health threat.
At present, fewer than 5% of staphylococcal strains are susceptible to penicillin, while approximately 40%-50% of Staph aureus isolated have developed resistance to newer semisynthetic antibiotics such as methicillin as well.
"It is inspiring that an inexpensive naturally visible wavelength of light can eradicate two common strains of MRSA.
Developing strategies that are capable of destroying MRSA, using mechanisms that would not lead to further antibiotic resistance, is timely and important for us and our patients," says Chukuka S. Enwemeka, PhD, FACSM, Co-Editor-in-Chief of the Journal and first author of the study.
The article will appear in the April 2009 issue (Volume 27, Number 2) of the peer-reviewed journal Photomedicine and Laser Surgery.
