What is Bacterial Biofilms ?

Biofilms are sessile communities of microorganisms attached to a biotic or abiotic surface and enclosed in a self-produced extracellular polymer matrix.  Biofilms are more frequently associated with chronic diseases due particularly to an increased resistance to both conventional biocides and host immune system.  Microorganisms that form biofilms include bacteriafungi and protists

Biofilms are often implicated in difficult-to-treat infections (chronic diseases, wound surfaces...). If biofilms are not promptly removed from wounds, they can delay healing and chronic infection can set in.

According to the Center for Disease Control and Prevention (CDC), every year at least 2 million Americans become infected with antibiotic-resistant bacteria, and at least 23,000 of them die as a direct result of these infections.
