Biofilms in Wound Healing

Unlike the Biofilm, the Results are Clear to See

About Biofilm

Bye, Bye Biofilms

60% of chronic wounds contain a biofilm1, which could delay healing. IODOSORB’s unique 4 in 1 action has been shown to prevent and disrupt mature biofilms of P. aeruginosa (in-vitro)2,3

Biofilms – A Reason for Delayed Healing

  • Biofilms are dynamic communities of bacteria and fungi living within a protective self-secreted matrix of sugars and proteins.
  • Research shows 60% of chronic wounds contain a biofilm.1
  • The presence of a biofilm has been shown to disrupt normal healing.
  • The result is a non-healing chronic wound stuck in the inflammatory phase of healing.
  • If you’ve treated a chronic wound that failed to progress, despite good wound care, it is possible you have been dealing with a biofilm.

IODOSORB’s Unique 4 in 1 Action

IODOSORB is an effective deslougher4,5,9,10 – which helps cleanse the wound bed and prepare it for effective healing.

IODOSORB has high absorption capacity4,5,6,7,10,11 – which assists with debridement by absorbing excess slough and debris.10,12

IODOSORB provides sustained release of iodine12,13 which has broad spectrum antimicrobial activity (in-vitro)6,10-12,14,15 to help reduce the microbial burden – helping remove the barriers to healing.

  • Local slow release of iodine.4,12
  • Effective against a broad range of bacteria, including MRSA (in-vitro).6,10-12,14,15
  • Changes color to indicate when change is required.13

IODOSORB has been shown to disrupt and substantially eradicate mature biofilms of P. aeruginosa (in-vitro).2,3
