Bakterien sind in der Lage, ihre Artgenossen in der Umgebung über unterschiedliche Signalmoleküle wahrzunehmen und über bestimmte Signalwege auf steigendes Zellwachstum gemeinschaftlich zu reagieren. Bezeichnet wird dieser Vorgang als Quorum Sensing und stellt ein Art bakterielle Sprache dar. Bei pathogenen Organismen führt diese Kommunikation meist zu

Trends in Quorum Sensing and Quorum Quenching
2023Quorum sensing (QS), controls the characteristics of microbe populations through the detection of the concentrations of signal molecules, which are not only released but also produced by bacteria. QS regulates both biochemical and physiological functions viz., release of quorum signal molecules, biofilm formation, reduction in virulence, production of ...

Antibiotic resistance is a global health concern. Strains of pathogenic microorganisms that have developed resistance to multiple antibiotics, such as MRSA, are extremely difficult to treat, and alternative methods for tackling pathogenic microorganisms are in demand.

Journal of Biotechnology, 2015
Bacteria use cell-to-cell communication systems based on chemical signal molecules to coordinate their behavior within the population. These quorum sensing systems are potential targets for antivirulence therapies, because many bacterial pathogens control the expression of virulence factors via quorum sensing networks.

Generation of Quorum Quenching Antibodies
2010The exchange of information within and among bacterial populations using small diffusible molecules has been termed "quorum sensing" (QS). Due to the extracellular distribution of the QS autoinducer molecules and the evolutionary highly conserved nature of signaling components, microbial QS systems represent an excellent target for anti-infective ...

Biotechnological applications of quorum quenching enzymes
Chemico-Biological Interactions, 2017Numerous bacteria use quorum sensing (QS) to synchronize their behavior and monitor their population density. They use signaling molecules known as autoinducers (AI's) that are synthesized and secreted into their local environment to regulate QS-dependent gene expression. Among QS-regulated pathways, biofilm formation and virulence factor secretion are

Towards quorum-quenching catalytic antibodies
Chem. Commun., 2009The development of a novel method to attenuate bacterial virulence is reported, which is based upon the use of designed transition-state analogues to select human catalytic antibodies capable of degrading bacterial quorum-sensing molecules.

Quorum‐sensing quenching by rhizobacterial volatiles
Environmental Microbiology Reports, 2011Summary We show that volatile organic compounds (VOCs) produced by rhizospheric strains Pseudomonas fluorescens B‐4117 and Serratia plymuthica IC1270 may act as inhibitors of the cell–cell communication quorum‐sensing (QS) network ...
