Bacteria talk to each other using N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signals. This signaling allows the bacteria to control gene expression of virulence factors and biofilms once a critical density has been achieved. This phenomenon, quorum sensing, is important when an infe... Read More
