Quorum Sensing: Survival Strategy of Microbes

Abstract

Sounds strange that bacteria can talk to each other, though not verbally like humans but with the help of chemical signals which bacteria produce by forming biofilm, producing virulence factors or developing antibiotic resistance. The process starts only when the bacterial cell reach a threshold density enough to produce signals which can be detected by the receptors. This unique communication system is very specific to every bacteria and therefore a clear understanding of the quorum sensing mechanism of bacteria helps in developing various techniques for combating the attack of deadly pathogens, production of antibiotics and also using quorum sensing in different sectors of microbiology.
