Using EDIC and EF we show how initial attachment occurred in less than 1 h following exposure to P. mirabilis (in artificial urine) to sections of silicone and hydrogel latex catheters was tracked over time (up to 24 days). Using a simple six-well plate system, attachment of P. Using an advanced light microscopy technique, episcopic differential interference contrast (EDIC) microscopy combined with epifluorescence (EF), we describe a non-destructive, non-contact, real-time imaging method used to track all stages of biofilm development from initial single cell attachment to complex crystalline biofilm formation. Previous studies have mainly relied on electron microscopy to describe this process but there remains a lack of understanding into the stages of biofilm formation. mirabilis attaching to all surfaces and forming encrustations. These crystalline biofilms have been found to develop on all catheter materials with P. Blockages often occur from crystalline deposits, formed as the pH rises due to the action of urease-producing bacteria the most commonly found species being Proteus mirabilis. The long-term use of indwelling catheters results in a high risk from urinary tract infections (UTI) and blockage.
