Regulation of virulence factors by quorum sensing in Vibrio harveyi. [PDF]
Vibrio harveyi is an important aquatic pathogen that produces several virulence factors. In this study, the effect of quorum sensing, bacterial cell-to-cell communication, on the production of the virulence factors caseinase, gelatinase, lipase ...

The first discovered and well-characterized bacterial quorum sensing (QS) system belongs to Vibrio fischeri, which uses N-acyl homo-serine lactones (AHLs) for cell-cell signaling. AHL QS cell-cell communication is often regarded as a cell density-dependent regulatory switch.

Effect of Autoinducer-2 Quorum Sensing Inhibitor on Interspecies Quorum Sensing
Bacterial drug resistance caused by overuse and misuse of antibiotics is common, especially in clinical multispecies infections. It is of great significance to discover novel agents to treat clinical bacterial infections. Studies have demonstrated that autoinducer-2 (AI-2), a signal molecule in quorum sensing (QS), plays an important role in ...

Quorum sensing as a mechanism to harness the wisdom of the crowds
Bacteria release and sense small molecules called autoinducers in a process known as quorum sensing. The prevailing interpretation of quorum sensing is that by sensing autoinducer concentrations, bacteria estimate population density to regulate the ...

Quorum sensing in African trypanosomes [PDF]
Many microbial eukaryotes exhibit cell-cell communication to co-ordinate group behaviours as a strategy to exploit a changed environment, adapt to adverse conditions or regulate developmental responses. Although best characterised in bacteria, eukaryotic microbes have also been revealed to cooperate to optimise their survival or dissemination.

Interfering with Bacterial Quorum Sensing [PDF]
Quorum sensing (QS) describes the exchange of chemical signals in bacterial populations to adjust the bacterial phenotypes according to the density of bacterial cells. This serves to express phenotypes that are advantageous for the group and ensure bacterial survival. To do so, bacterial cells synthesize autoinducer (AI) molecules, release them to the

Dishonest Signaling in Microbial Conflicts
Quorum sensing is a cell-cell communication system that bacteria use to express social phenotypes, such as the production of extracellular enzymes or toxins, at high cell densities when these phenotypes are most beneficial.

Penghambatan Quorum Sensing Sebagai Alternatif Terapi Penyakit Infeksi Yang Disebabkan Oleh Bakteri [PDF]
The latest discoveries in the field of microbiology have proved that bacteria communicate eachother. The process of cell to cell communication is called quorum sensing. Quorum sensing wasfirst discovered in two luminous bacteria called Vibrio harveyi and

Acinetobacter quorum sensing contributes to inflammation-induced inhibition of orthopaedic implant osseointegration [PDF]
Implant infection impairs osseointegration of orthopaedic implants by inducing inflammation. Acinetobacter spp. are increasingly prevalent multi-drug resistant bacteria that can cause osteomyelitis. Acinetobacter spp.

Candida and invasive candidiasis: Back to basics. [PDF]
The ubiquitous Candida spp. is an opportunistic fungal pathogen which, despite treatment with antifungal drugs, can cause fatal bloodstream infections (BSIs) in immunocompromised and immunodeficient persons. Thus far, several major C.
