Over the last five decades, the overuse of antibiotics has led to widespread resistance in pathogenic bacteria. This resistance, combined with slow progress in designing new therapeutics, has prompted a crisis in the treatment of many once easily curable diseases. Great effort has been put into developing new compounds that effectively target essential features of microbial life, but for the majority, only their growth inhibitory effects have been extensively studied. How low concentrations of antimicrobials affect bacterial survival and, most importantly, whether or not the molecules might have other functions at subinhibitory concentrations (SICs) are outstanding questions. Pioneering studies on the global transcriptome response of many important human pathogens to SICs of antibiotics have demonstrated that these molecules can affect the expression of genes related to virulence, colonization, motility, stress response, and/or biofilm formation. Further research has shown that some of these effects result from interference with bacterial cellÀcell communication. This observation has prompted the idea that antibiotics might actually act as signal molecules in natural environments, facilitating intra-or interspecies interactions within microbial communities. In this review, we highlight examples of the effect of diverse clinically relevant antimicrobials and other natural products on bacterial developmental programs, with an emphasis on biofilm formation. How this knowledge can be used to improve the current use of antibiotics and how new therapies that target alternative microbial processes might be developed will also be discussed.
