Biofilms are communities of aggregated bacterial cells embedded in a self-produced extracellular polymeric matrix. Biofilms are recalcitrant to antibiotic treatment and immune defenses and are implicated in many chronic bacterial and fungal infections. In this review, we provide an overview of the contribution of biofilms to persistent infections resistant to antibiotic treatment, the impact of multispecies biofilms on drug resistance and tolerance, and recent advances in the development of antibiofilm agents. Understanding the mechanisms of antibiotic resistance and tolerance in biofilms is essential for developing new preventive and therapeutic strategies and curbing drug resistance.
