Quorum sensing allows the bacteria to coordinate their actions with respect to each other and the environment. By singling out signal substances on Wednesday, they will know how many relatives are next to them. With increasing concentration of substances, all bacteria change their behavior. Quorum sensing allows bacteria to respond to a deficiency of nutrients, competitors and environmental changes. Pathogenic bacteria with quorum sense resist host immune system
It turned out that "collectivism" is necessary for a certain type of movement of microbial cells, but most importantly: under the control of "quorum sensing", pathogenic bacteria form films that are difficult to access for antibiotics, and synthesize virulence factors.
