Pseudofactin II inhibits biofilm formation on silicone urethral catheters. The organisms were grown overnight at 37°C in a test-tube with sterile urethral catheters containing medium (A) with and without 0.25 mg/ml pseudofactin II and (B) where the urethral catheters was pre-incubated with biosurfactant at concentration 0.25 mg/ml as described in the text. Biofilms were visualized by staining with crystal violet.
