One of the key mechanisms enabling bacterial cells to create biofilms and regulate crucial life functions in a global highly synchronized way is communication system called quorum sensing (QS). QS cell-to-cell process that depends on population density mediated by small signalling molecules autoinducers (AIs). In bacteria, controls biofilm formation through regulation gene expression involved extracellular polymeric matrix (EPS) synthesis, virulence factor production, stress tolerance metabolic adaptation. Forming one antimicrobial resistance (AMR). A common feature human pathogens ability form biofilm, which poses serious medical issue due their high susceptibility traditional antibiotics. Because associated with formation, there belief inhibition activity quenching (QQ) may provide alternative therapeutic methods for treating microbial infections. This review summarises recent progress research, focusing biofilms, especially those formed pathogenic become resistant antibiotic treatment. Subsequently, potential approach highlighting innovative non-antibiotic strategies control AMR bacteria has been discussed.
