Define the word "quorum sensing" and explain (at the cellular or biochemical level) the mechanism by which microbes participate in this phenomenon.
Give a real-world example of quorum sensing by a) naming a microorganism that carries out quorum sensing, b) describing the microbial activity that is induced, and c) briefly describing the advantage this activity provides to the microbe .
Given what you know about the role of quorum sensing in the context of certain infections microorganisms and the human diseases they cause, describe a means of treatment or therapy that would take advantage of a pathogen's reliance on quorum sensing.
