The Quorum sensing of Xylella fastidiosa

The quorum sensing is a mechanism involving chemical compounds that create a line of communication for various bacterium which regulate their behavior in the confined of their population. There a many ways of communications used like peptides, lactones or fatty acids. After reaching a high concentration of this molecules bacteria are enable to detect them and also became enable to change the expressions of specifics genes. This change results to lead a new phenotype in a high population of bacteria. At the opposite Quorum Quenching is to blur Quorum Sensing and therefore stop the communication of bacteria. It is used by procaryote, for example between bacteria population between populatons of bacteria and eucaryote to control pathogenes.
