What is "biofilm" in the context of wound care?

In wound care, biofilm is defined as a community of bacteria that adhere to a surface and are embedded within a protective matrix. This matrix, composed of polysaccharides and proteins, shields the bacteria from the host's immune system and antimicrobial treatments, making infections more difficult to treat. The presence of biofilms in chronic wounds can lead to persistent infection and delayed healing, as the bacteria within can become resistant to standard therapies.

Understanding biofilm is crucial for effective wound management since it highlights the importance of targeted interventions that can disrupt these protective structures. Treatment strategies may include specialized dressings, surgical debridement, or advanced therapeutic agents designed to penetrate the biofilm and eliminate bacteria, ultimately facilitating the healing process.
