Soft-rot bacteria Pectobacterium and Dickeya use N-acyl homoserine lactones (NAHSLs) as diffusible signals for coordinating quorum sensing communication. The production of NAHSLs was investigated in a set of reference strains and recently-collected isolates, which belong to six species and share the ability to infect the potato host plant. All the pathogens produced different NAHSLs, among whic...

Numerous bacteria utilize molecular communication systems referred to as quorum sensing (QS) to synchronize the expression of certain genes regulating, among other aspects, the expression of virulence factors and the synthesis of biofilm. To achieve this process, bacteria use signaling molecules, known as autoinducers (AIs), as chemical messengers to share information. Naturally occurring strat...

Abstract Quorum sensing (QS) plays an important role in microbial aggregation control. Recently, the optimization of biological waste treatment systems by QS regulation gained increasing attention. The effects on performances and biofilm were frequently investigated. To understand state art regulation, this review summarizes methods enhancement inhibition systems. Typical include adding exogeno...

background and objectives: there is increasing emergence of multidrug resistant pseudomonas aeruginosa (mdrpa) strains and drug resistance is positively-correlated with biofilm-forming ability. since about 10% of p. aeruginosa genome is controlled by quorum sensing (qs), alteration in its antibiotic susceptibility by targeting qs was the focus of the present study. materials and methods : one d...

Introduction. Nosocomial contaminants such as Pseudomonas aeruginosa and Serratia marcescens are increasingly developing resistance to many antibiotics. One of the promising alternatives that may complement, if not substitute, use antibiotics is quorum quenching, process interfering with chemical signals mediate communication between microorganisms. Eleusine indica, a ubiquitous grass used trad...
