The role of antifungals agents on Candida glabrata biofilms matrix composition [PDF]

, 2010
Candida glabrata was considered, for years, a relatively non-pathogenic saprophyte of the normal flora of healthy individuals and as no causative agent of serious infection in humans.

The autoinducer synthases LuxI and AinS are responsible for temperature-dependent AHL production in the fish pathogen Aliivibrio salmonicida [PDF]

, 2015
Published version, also available at http://dx.doi.org/10.1186/s12866-015-0402-zBackground: Quorum sensing (QS) is a cell-to-cell communication system used by bacteria to regulate activities such as virulence, bioluminescence and biofilm formation.

Onion‐pathogenic Burkholderia species: Role and regulation of characterized virulence determinants

Plant Pathology, Volume 73, Issue 9, Page 2281-2297, December 2024.
Protein secretion systems and toxoflavin are well‐characterized virulence factors in onion‐pathogenic Burkholderia species. The tofIMR quorum‐sensing system and qsmR regulate multiple Burkholderia virulence factors. Abstract Members of the bacterial genus Burkholderia are a routine threat to onion production worldwide.

Quorum-sensing signaling is required for production of the antibiotic pyrrolnitrin in a rhizospheric biocontrol strain of Serratia plymuthica [PDF]

, 2017
One mechanism that bacteria have adopted to regulate the production of antimicrobial compounds is population-density-dependent LuxRI-type quorum sensing (QS), exploiting the production of N-acyl homoserine lactone (AHL) autoinducer signals. In biocontrol

Matching Together Living Cells and Prototissues: Will There Be Chemistry?

ChemBioChem, Volume 25, Issue 18, September 16, 2024.
In the field of tissue engineering, the combination of synthetic and living tissues could be the turning point. In this work we review examples of hybrid protocell/living cell and prototissue/living cell systems, focusing on the chemistry that makes the integration between non‐living and living matter efficient.

N‐acyl homoserine lactone cell–cell diffusible signalling in the Ralstonia solanacearum species complex

Molecular Plant Pathology, Volume 25, Issue 8, August 2024.
Pathogens of the Ralstonia solanacearum species complex (RSSC) regulate virulence gene expression via four interconnected quorum‐sensing (QS) signalling systems ensuring a timely response in different environmental settings. Abstract Ralstonia solanacearum species complex (RSSC) includes soilborne bacterial plant pathogens with worldwide distribution ...

Nanomaterials Regulate Bacterial Quorum Sensing: Applications, Mechanisms, and Optimization Strategies

Advanced Science, Volume 11, Issue 15, April 17, 2024.
This review focuses on the specific mechanisms by which nanomaterials regulate bacterial quorum sensing in the signal supply and signal transduction cascade processes. Furthermore, based on the influencing factors of nanomaterial itself and environment, optimization strategies to enhance the QS regulatory activity are comprehensively summarized.

Potential of the quorum‐quenching and plant‐growth promoting halotolerant Bacillus toyonensis AA1EC1 as biocontrol agent

Microbial Biotechnology, Volume 17, Issue 3, March 2024.
Bacillus toyonensis AA1EC1 promotes plant growth and protects plants against phytopathogenic bacteria through quorum quenching mechanisms based on the enzymatic degradation of AHLs. Abstract The use of fertilizers and pesticides to control plant diseases is widespread in intensive farming causing adverse effects together with the development of ...
