……………..unless you are a bacteria.


The more elaborate our means of communication the less we communicate joseph priestley

  • Bacteria do not just act randomly, they actually communicate and coordinate with each other.

They do this by releasing signalling molecules into their environment.

  • Not only are bacteria able to release signalling molecules in the environment, bacteria are also able to “sense” how many molecules are in the area.

  • This ability to sense signalling molecules and other bacteria in the area is referred to today as…

Sensing!

  • The quorum sensing ability is helpful for bacteria in a number of ways. It allows a group of bacteria to respond quickly to an environmental change, an attack from other micro-organisms, or a potentially harmful toxin in the area.

  • It also allows pathogenic bacteria to coordinate in a way that will break past a host’s immune system and infect the host.

  • Some bacteria are able to sense signalling molecules in the environment that were released by a different kind of bacteria.

  • This can lead to interspecies communication

  • The variety of signalling molecules is so large, each molecule can be considered a word in a language. Bacteria will have a different response to each molecule they sense.

  • Some research in quorum sensing includes a study in how to interfere with a bacteria’s quorum sensing and signalling molecules. This will allow us to change the quorum sensing system of pathogenic bacteria and prevent them from being dangerous.
