Pseudomonas aeruginosa Quorum Sensing

2022
Pseudomonas aeruginosa, like many bacteria, uses chemical signals to communicate between cells in a process called quorum sensing (QS). QS allows groups of bacteria to sense population density and, in response to changing cell densities, to coordinate behaviors. The P.

Quorum Sensing

2014
Nowadays, cell to cell communication and co-operation has been proved to be not only found in eukaryotes,but also in prokaryotes. In bacteria, this communication is termed quorum sensing (QS). QS enables bacteria toact as multicellular organisms. Bacteria determine small hormone-like molecules termed auto inducer which producedby another bacteria by ...

Quorum Sensing

Science Signaling, 2001
Bacteria sense the presence of each other through the production and detection of pheromones. Agrobacterium tumefaciens , a plant pathogen, produces Agrobacterium autoinducer (AAI), which is a ligand for the transcription factor TraR.

Quorum Sensing in Bacteria

Annual Review of Microbiology, 2001
▪ Abstract  Quorum sensing is the regulation of gene expression in response to fluctuations in cell-population density. Quorum sensing bacteria produce and release chemical signal molecules called autoinducers that increase in concentration as a function of cell density.

Trypanosome Signaling—Quorum Sensing

Annual Review of Microbiology, 2021
African trypanosomes are responsible for important diseases of humans and animals in sub-Saharan Africa. The best-studied species is Trypanosoma brucei, which is characterized by development in the mammalian host between morphologically slender and stumpy forms. The latter are adapted for transmission by the parasite's vector, the tsetse fly.

Quorum Sensing in Staphylococci

Annual Review of Genetics, 2008
The staphylococcal agr locus encodes a quorum sensing (QS) system that controls the expression of virulence and other accessory genes by a classical two-component signaling module. Like QS modalities in other Gram-positive bacteria, agr encodes an autoactivating peptide (AIP) that is the inducing ligand for AgrC, the agr signal receptor.

Quorum-sensing in Rhizobium

Antonie van Leeuwenhoek, 2002
Quorum-sensing signals are found in many species of legume-nodulating rhizobia. In a well-characterized strain of R. leguminosarum biovar viciae, a variety of autoinducers are synthesised, and all have been identified as N-acyl-homoserine lactones.

Quorum sensing of pathogenic bacteria and quorum-sensing inhibitors

Chinese Science Bulletin, 2012
The emergence of antibiotic-resistant and especially multidrug-resistant pathogenic bacteria intensifies the need to screen new drug targets and develop new antibacterial drugs. Bacteria coordinate their virulent behaviors in a cell density-dependent manner known as quorum sensing (QS).
