What is it about?

Here we describe the physiological mechanism of treating persistent biofilms of Pseudomonas aeruginosa with the antioxidant Glutathione, a major pathogen in Cystic Fibrosis (CF) and other hospital-acquired infections. We show potential clinical utility for use in combination with antibiotics to reduce overall bacterial load in a specialised media that mimicks CF sputum, the site of long-term infections in individuals with CF.

Why is it important?

Bacterial biofilms as a structure render traditional antibiotics ineffective due to structural hinderance and chemical inactivation. By disrupting biofilms with novel, non-toxic treatments such as host antioxidants, the protective effects of biofilms are nullified.
