Binding of two bacterial biofilms to dialkyl carbamoyl chloride (DACC)-coated dressings in vitro
To date only planktonic bacteria have been shown to bind irreversibly to dialkyl carbamoyl chloride (DACC)-coated Cutimed Sorbact dressings. Therefore, this study was designed to determine whether bacterial biofilm bound to the DACC-coated dressing in vitro.
Samples of DACC-coated dressings and uncoated control dressings (supplied by BSN medical Ltd, Hull) were placed in contact with plastic coverslips on which biofilms of either Pseudomonas aeruginosa or methicillin-resistant Staphylococcus aureus (MRSA) had been cultivated for 24 hours. Dressing samples were examined by scanning electron microscopy to detect the presence of biofilm.
Pseudomonas aeruginosa biofilm bound avidly to both DACC-coated and uncoated dressing samples. MRSA bound more extensively to DACC-coated dressings than to uncoated samples.
Biofilms of two different test bacteria bound to dressings in vitro with the DACC-coating on the dressings enhancing the binding of MRSA biofilm.
