I sin enklaste form är quorum sensing bakteriers sätt att kommunicera. Det beskriver förmågan för vissa bakterier att uppvisa ett samordnat beteende vid en särskild populationsdensitet. Dessa bakterier förlitar sig på produktionen, ackumulationen och påföljande reaktion av diffunderbara signalmolekyler. Dessa signalmolekyler ackumuleras i miljöer som kan upprätthålla en tillräckligt hög population, eller kvorum, av det signalproducerande bakterierna.
