Discovery of a new defense mechanism in bacteria - EurekAlert


When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defence mechanism using cell-to-cell communication to ‘warn’ unaffected bacteria, which can then anticipate, shield themselves and spread the warning signal. This mechanism has just been described for the first time by a team of scientists from CNRS and Université de Toulouse III – Paul Sabatier. It paves the way for the development of new, more effective antibiotic treatments that can target this bacterial communication system.
