Effects of Selected Wound Dressings and Remedies on Planktonic Bacteria and Bacterial Biofilms of Staphylococcus aureus and Pseudomonas aeruginosa

The overall aim of this research is to evaluate the effect of some approaches of treating wounds and the use of wound dressings of on the planktonic bacteria and bacterial biofilms of Staphylococcus aureus and Pseudomonas aeruginosa, two major bacterial species found in wounds. The wound treatments were dressings containing either honey or silver, and commercial hand gels with alcohol. Results indicate that dressings that contain Manuka honey were efficacious against planktonic bacteria of S. aureus, whereas, dressings with silver were most effective against planktonic Pseudomonas aeruginosa. Panaderm (antibiotic) showed the strongest activity against both planktonic S. aureus and P. aeruginosa. The effect of wound treatments on non-established and established bacterial biofilms after 24 and 48 hours after application, show that dressings were effective against the biofilm of S. aureus. However, a non-adherent dressing with Activon Manuka Honey was ineffective against Pseudomonas aeruginosa biofilm. Overall, except for hand gels, the wound remedies tested show remarkable activity against the biofilms of S. aureus and P. aeruginosa.Read Complete Article at ijSciences: V4201509837 AND DOI: http://dx.doi.org/10.18483/ijSci.83
