Abstract

Antimicrobial resistance is a major health issue inducing the inefficiency of antimicrobial drugs. Indeed, pathogenic microorganisms become resistant when frequently exposed to antimicrobial drugs. In particular, when bacteria are attached to a surface and expand as a biofilm, they become more resistant to antimicrobials because single or multiple bacterial species are embedded in a slimy extracellular polymeric substance that acts like a shield. Biofilms often contaminate medical devices and food industrial equipment, thus leading to infections and food spoilage. Here, we review the basics of biofilm development from a planktonic bacterium; signaling in biofilm and relationship with antimicrobial resistance; biofilm control and destruction strategies using quorum sensing inhibitors, ultrasound, acidic electrolyzed water, and enzymatic and combination killing; and emerging approaches, such as bacteriophage-mediated disruption and antimicrobial peptides to control bacterial biofilms.
