“Researchers from The University of Liverpool and The Royal Liverpool University NHS Trust tested different strains of the keratitis-causing bacterium Pseudomonas aeruginosa for their ability to survive in a commonly used contact lens cleaning solution. The team compared nine clinical strains of P. aeruginosa, taken from hospital patients in the UK, with P. aeruginosa strain 9027, the standard strain used by lens solution manufacturers.” That’s part of a post on Science Codex. “The results showed that the majority of clinical strains tested were killed within 10 minutes of being immersed in the contact lens solution, comparable with the standard reference strain. However, one clinical isolate, P. aeruginosa strain 39016 – associated with a more severe case of keratitis with a prolonged healing time – was able to survive for over four hours, much longer than the reference strain.” Read more.
