United KingdomPseudomonas aeruginosa, a bacterium responsible for severe infections in hospitals and in individuals with cystic fibrosis, has been found to become more resistant to antibiotics when physically confined within elastic materials. Researchers at EPFL discovered that when P. aeruginosa grows in tight, elastic environments such as synthetic gels, the resulting mechanical pressure alters the bacteria's physiology, increasing their ability to survive antibiotic treatments. The study demonstrated that this increased survival was not due to reduced antibiotic penetration but rather due to physiological changes caused by the physical constraints. In stiffer gels, which exert greater pressure, the bacteria exhibited significantly higher survival rates under antibiotic exposure compared to those in softer gels. These findings were consistent across multiple strains, including clinical isolates from cystic fibrosis patients.
