SIGNIFICANT GENETIC COMMITMENT. “A significant portion of a bacterial genome (4%–10%) and proteome (20% or more) can be influenced by quorum signaling, which suggests that quorum sensing is a mechanism used by pathogenic bacteria not only to modulate virulence factor production but also to adapt to the metabolic demands of living in communities.”
