biofilm
Pronunciation: BY-oh-film
A protective matrix of bacteria and extracellular substances that adheres to burn wound surfaces.
Full Definition
Biofilm in burn care refers to a structured community of bacteria encased in a self-produced polymeric matrix that strongly adheres to the wound surface. These bacterial communities are particularly problematic in burn wounds because they are highly resistant to antimicrobial treatments and can significantly impair wound healing. Biofilm formation is a major cause of chronic burn wound infections and delayed healing, often requiring aggressive debridement and specialized antimicrobial strategies for management.
Usage
Usage note: Distinguish from simple bacterial contamination; biofilm implies an organized, adherent microbial community.
