Isolation of Quorum Quenching Microorganisms and Screening Methods

, 2023
Quorum sensing is one of the regulatory mechanisms of gene expression that has received the most attention in the last two decades. In consequence, its interruption by means of quorum quenching (QQ) strategies is highly relevant.

Quorum quenching revisited-from signal decays to signalling confusion [PDF]

, 2012
In a polymicrobial community, while some bacteria are communicating with neighboring cells (quorum sensing), others are interrupting the communication (quorum quenching), thus creating a constant arms race between intercellular communication. In the past

Evolution of Resistance to Quorum Quenching in Digital Organisms [PDF]

Artificial Life, 2012
Quorum sensing (QS) is a collective behavior whereby actions of individuals depend on the density of the surrounding population. Bacteria use QS to trigger secretion of digestive enzymes, formation and destruction of biofilms, and, in the case of pathogenic organisms, expression of virulence factors that cause disease. Investigations of mechanisms that

Quorum Sensing and Self-Quorum Quenching in the Intracellular Pathogen Brucellamelitensis

PLoS ONE, 2013
Brucella quorum sensing has been described as an important regulatory system controlling crucial virulence determinants such as the VirB type IV secretion system and the flagellar genes. However, the basis of quorum sensing, namely the production of autoinducers in Brucella has been questioned.

Two homologous Agr-like quorum-sensing systems cooperatively control adherence, cell morphology, and cell viability properties in Lactobacillus plantarum WCFS1 [PDF]

, 2008
A two-component regulatory system of Lactobacillus plantarum, encoded by genes designated lamK and lamR (hpk10 and rrp10), was studied. The lamK and lamR genes encode proteins which are highly homologous to the quorum-sensing histidine kinase LamC and ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

DETECTION OF QUORUM QUENCHING -PRODUCING BACTERIA FROM RHIZOSPHERE SOIL AS A BIOCONTROL AGENTS [PDF]

, 2021
Quorum sensing is known as a communication mechanism among bacteria to control gene expression such as bioluminescence, pigmentation, and pathogenicity. Quorum quenching is known as inhibition of quorum sensing activity.

Oral microbiome and homeostatic regulation of periodontal health: From dysbiosis to precision intervention

VIEW, EarlyView.
Periodontal homeostasis is maintained by coordinated interactions between the oral microbiome and host. Dysbiosis disrupts this ecological balance and contributes to periodontal disease, whereas multi‐omics, artificial intelligence, and microbiome‐based interventions provide emerging opportunities for precision diagnosis, ecological restoration, and ...
