A novel finding of intra-genus inhibition of quorum sensing in Vibrio bacteria
Scientific Reports, 2022 Quorum sensing is the process by which microbial cells sense and respond to the co-presence of others in their surrounding, through the detection of their autoinducers associated with gene expression regulation and thereby controlling many physiological ...

Autoinducer 2 Affects Biofilm Formation byBacillus cereus [PDF]
Applied and Environmental Microbiology, 2006 ABSTRACTCell-free supernatants from growingBacillus cereusstrain ATCC 10987 induced luminescence in aPhotorhabdus luminescensΔluxSmutant, indicating the production of functional autoinducer 2 (AI-2). The exogenous addition of in vitro synthesized AI-2 had an inhibitory effect on biofilm formation byB.

, 2016 Bacteria communicate using external chemical signals called autoinducers (AI) in a process known as quorum sensing (QS). QS efficiency is reduced by both limitations of AI diffusion and potential interference from neighboring strains.

Regulation of autoinducer production in Salmonella typhimurium [PDF]
Molecular Microbiology, 1999 Salmonella typhimurium strain LT2 secretes an organic signalling molecule that can be assayed by its ability to activate one of two specific quorum‐sensing systems in Vibrio harveyi. Maximal activity is produced during mid‐ to late exponential phase when S. typhimurium is grown in the presence of glucose or other preferred carbohydrates. The signal is

The Evolution of Quorum Sensing as a Mechanism to Infer Kinship. [PDF]
, 2016 Bacteria regulate many phenotypes via quorum sensing systems. Quorum sensing is typically thought to evolve because the regulated cooperative phenotypes are only beneficial at certain cell densities. However, quorum sensing systems are also threatened by

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome
Advanced Science, EarlyView.By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...

Functional analysis of the Pseudomonas aeruginosa autoinducer PAI [PDF]
Journal of Bacteriology, 1996 A series of structural analogs of the Pseudomonas aeruginosa autoinducer [PAI, N-3-oxo-dodecanoyl homoserine lactone] were obtained and tested for their ability to act as autoinducers in stimulating the expression of the gene for elastase (lasB) by measuring beta-galactosidase production from a lasB-lacZ gene fusion in the presence of the ...

Quorum sensing: An imperative longevity weapon in bacteria [PDF]
, 2018 Bacterial cells exhibit a complex pattern of co-operative behaviour as shown by their capacity to communicate amongst each other. Quorum sensing (QS) is a generic term used for bacterial cell-to-cell communication which secures survival of its species ...

Mechanism of Vibrio cholerae Autoinducer-1 Biosynthesis
ACS Chemical Biology, 2011 Vibrio cholerae, the causative agent of the disease cholera, uses a cell to cell communication process called quorum sensing to control biofilm formation and virulence factor production. The major V. cholerae quorum-sensing signal CAI-1 has been identified as (S)-3-hydroxytridecan-4-one, and the CqsA protein is required for CAI-1 production.
