Unfortunately, bacterial pathogens have outpaced our abilities to manage them. The expanding global distribution of crops has placed an added incentive on finding new ways to increase production and enhance disease resistance of plants and to extend the shelf lives of plant-derived products. Meanwhile, as the world's population continues to increase rapidly, agricultural markets are tasked with meeting worldwide nutritional needs.

We find ourselves facing a significant moment in modern health care where many antibiotics have lost their effectiveness in treating life-threatening and debilitating diseases. Nevertheless, various QSI successes have rightfully perpetuated excitement surrounding new potential therapies, and this review highlights promising QSI leads in disrupting pathogenesis in both plants and animals.Ĭurrent Obstacles in the Treatment of Bacterial Pathogens Overall, the evidence suggests that QSI therapy may be efficacious against some, but not necessarily all, bacterial pathogens, and several failures and ongoing concerns that may steer future studies in productive directions are discussed. The identification and development of chemical compounds and enzymes that facilitate quorum-sensing inhibition (QSI) by targeting signaling molecules, signal biogenesis, or signal detection are reviewed here. An antivirulence approach by which quorum sensing is impeded has caught on as a viable means to manipulate bacterial processes, especially pathogenic traits that are harmful to human and animal health and agricultural productivity. With the ongoing emergence of antibiotic-resistant pathogens, there is a current need for development of alternative therapeutic strategies.

Its use by bacterial pathogens to regulate genes that promote invasion, defense, and spread has been particularly well documented.

Cell-cell communication, or quorum sensing, is a widespread phenomenon in bacteria that is used to coordinate gene expression among local populations.
