Biofilm Formation and Antibiotic Susceptibility Patterns in Contact Lens-Associated Bacteria

This study shows that bacteria present on contact lenses of asymptomatic users possess significant biofilm-forming capacity. We conclude that A. xylosoxidans and coagulase-negative Staphylococcus were predominant and capable biofilm formers. CRB was found to be a convenient qualitative method for detecting EPS production in this study. The bacterial attachment on CL may vary with physiological conditions. These findings reflect presence of bacteria rather than active infection and highlight the importance of hygiene and preventive strategies during contact lens use.
