Although unicellular, bacteria are highly interactive and employ a range of cell-to-cell communication or 'quorum sensing (QS)' systems for promoting collective behaviour within a population. QS is generally considered to facilitate gene expression only when the population has reached a sufficient cell density and depends on the synthesis of small molecules that diffuse in and out of bacterial cells. As the bacterial population density increases, so does the synthesis of QS signal molecules and…

Interkingdom signaling and its consequences for human health
TLDR
Quorum sensing-signals themselves can induce specific responses of the human cell that can also be relevant for the infective process, and this regulation is physiologically relevant since the deletion of genes encoding the components of the QS regulatory circuits reduces P. aeruginosa virulence in mice.
Quorum Sensing in Microbes and their Function in Modulating Antibiotic Synthesis
TLDR
An understanding of the current view of quorum sensing and their function in modulating antibiotics synthesis and an orphan quorum-sensing receptor is presented.
Quorum Sensing in Bacterial Pathogenesis and Virulence
TLDR
The emergence of multi drug resistant pathogens and their ability to form biofilm, infers a current need for development of alternative therapeutic strategies towards the bacterial quorum sensing phenomenon.
Bacterial quorum sensing: circuits and applications
TLDR
In this review, attention is drawn on the recent applications of QS in development of synthetic biology modules, for studying the principles of pattern formation, engineering bi-directional communication system and building artificial communication networks.
Implication of Quorum Sensing System in Biofilm Formation and Virulence
TLDR
These QS microbes could be undoubtedly expensive tools for biologists to inquire and comprehend the progress of cooperation and cell to cell communication, wherein the realistic applications of this acquaintance will befall well-known in conjunction with basic acquaintance.
Quorum Sensing: Communication Complexity for Resilience of Plant-Microbe Interaction
TLDR
The present chapter will be focused on quorum sensing molecules and their role in plant-microbe interaction.
Quorum sensing for improved production of industrially useful products from filamentous fungi
TLDR
The cell-densities of filamentous fungi are correlated to the regulation of their different physiological responses to trigger different cellular responses such as sporulation, and secondary metabolism in Aspergillus terreus.
Different aspects of bacterial communication signals
TLDR
Different communication signal molecules, and the various chemical, physical and genomic factors known to synthesize signals are described, including some signal-degrading enzymes or compounds and the interaction of QSSMs with eukaryotic metabolism are discussed.

Look who's talking: communication and quorum sensing in the bacterial world
TLDR
Quorum sensing enables a bacterial population to mount a co-operative response that improves access to nutrients or specific environmental niches, promotes collective defence against other competitor prokaryotes or eukaryotic defence mechanisms and facilitates survival through differentiation into morphological forms better able to combat environmental threats.
Extracellular communication in bacteria
TLDR
The discovery and characterisation of natural molecules which antagonize quorum sensing-mediated responses has created new opportunities for the design of novel anti-infective agents which control infection through the attenuation of bacterial virulence.
Quorum sensing, virulence and secondary metabolite production in plant soft-rotting bacteria
TLDR
The models for AHL-based regulation of carbapenem antibiotic production in Erwinia and the importance of quorum sensing in the production and secretion of virulence determinants by ErwinIA are reviewed and its interplay with other regulatory systems are discussed.
Evolutionary theory of bacterial quorum sensing: when is a signal not a signal?
TLDR
This review seeks to integrate the evolutionary literature on animal signalling with the microbiological literature on QS, and asks whether QS within bacteria is true signalling or whether these molecules are also used as cues or for the coercion of other cells.
Quorum-sensing blockade as a strategy for enhancing host defences against bacterial pathogens
TLDR
The use of QS signal blockers to attenuate bacterial pathogenicity, rather than bacterial growth, is therefore highly attractive, particularly with respect to the emergence of multi-antibiotic resistant bacteria.
Differential Immune Modulatory Activity of Pseudomonas aeruginosa Quorum-Sensing Signal Molecules
TLDR
The comparative effects of two chemically distinct and endobronchially detectable QSSM, N-(3-oxodododecanoyl)-l-homoserine lactone and 2-heptyl-3-hydroxy-4 (1H)-quinolone or the Pseudomonas quinolone signal (PQS), on human leukocytes exposed to a series of stimuli designed to detect differential immunological activity in vitro are determined.
Cross-kingdom signalling: exploitation of bacterial quorum sensing molecules by the green seaweed Ulva
TLDR
It has been demonstrated that the detection of AHLs results in calcium influx into the zoospore, the first example of a calcium signalling event in a eukaryote in response to bacterial quorum sensing molecules.
A Mobile Quorum-Sensing System in Serratia marcescens
TLDR
It is reported that the spnIR quorum-sensing system identified in the enterobacterium Serratia marcescens strain SS-1 is carried in a transposon, TnTIR, which has common characteristics of Tn3 family transposons and is mobile between chromosomes and plasmids of different enterobacterial hosts.
