The disease-causing bacteria Pseudomonas aeruginosa uses a cell-cell communication process called quorum sensing to orchestrate collective behaviors required for disease development. Quorum sensing relies on the group-wide detection of signal molecules called autoinducers. The production and detection of autoinducers are required for disease development. A bacterial infection is not a static event; bacteria must first colonize inside the body, then proliferate and survive within the body, and eventually transfer into another person. Since conditions within the body are different than outside, and conditions within the body might change during the course of the infection, microbial adaptation is key to the infection process to ensure the survival of the bacteria. We will examine the role of microbial adaption in altering autoinducer concentrations to modulate disease-developing traits of Pseudomonas aeruginosa. This will help us to better understand how we could potentially block cell-cell signaling to prevent disease development.
