What is biofilm and its significance?

Biofilms are complex aggregations of microorganisms marked by the secretion of a protective and adhesive matrix. This matrix is often compared to a mucous membrane and is created by bacteria to shield themselves from external threats like antimicrobials and antibiotics. Biofilms can form on various surfaces, both within and outside the body, including the gut and teeth 1 2.

Significance of Biofilms:

1. Protection for Bacteria: The biofilm matrix protects resident bacteria from being easily eradicated by the immune system or antibiotics, making infections persistent and harder to treat 1.

2. Oral Health: In the mouth, biofilms contribute to the formation of plaque on teeth. If not properly managed through brushing and flossing, this can lead to dental problems such as cavities and gum disease 3 4.

3. Medical Challenges: In medical contexts, biofilms can form on implants and invasive devices, posing significant risks for infections that are challenging to detect and treat. For example, biofilm-related infections can complicate conditions ranging from dental plaque to chronic diseases like Lyme disease and infections associated with breast implants 5 6.

4. Resistance to Treatment: Biofilms are particularly problematic as they can shield bacteria from the effects of antibiotics and natural antimicrobial agents, requiring higher doses or alternative treatments to be effective 1 2.

Understanding and managing biofilms is crucial in medical treatments to ensure that infections and other related health issues can be effectively treated.
