MetabolomicsEvidence for quorum sensing and differential metabolite production by Ruegeria pomeroyi in response to DMSP
Microbial alteration and remineralization of organic matter in the ocean play essential roles in the carbon cycle. The impact of individual compounds as either growth substrates or infochemicals is still poorly constrained in models, particularly for organisms with relatively versatile genomes. Here...

MetabolomicsRegulation of drug resistance to enrofloxacin in Pasteurella multocida strains from cattle by quorum-sensing acyl-homoserine lactone signaling molecules

Pasteurella multocida (Pm) is a significant cause of respiratory disease in beef cattle, with serious consequences for the cattle industry. The bacterial quorum-sensing (QS) system is used for communication and regulation of various processes, including bacterial growth, virulence, biofilm format...

TranscriptomicsTranscriptional analysis of three quorum sensing signals add in experiment inYersinia pestis CO92 at 37M-BM-0C
Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of quorum sensing was investigated by comparing transcript profiles when three quorum-sensing signals are added in. The strai...

MetabolomicsQuercetin alleviates ETEC K88-induced host injury by driving the circulation and fluctuation of AHL-like quorum-sensing signaling molecules in the blood–liver–colon system

Abstract:

Background: Quercetin is a flavonoid with various probiotic properties, demonstrating anti-inflammatory, anti-oxidative, anti-cancer, and anti-obesity effects in humans and animals. However, quercetin’s effect on enterotoxigenic Escherichia coli (ETEC) K88-induced host body injury...

TranscriptomicsQuorum sensing and silencing in Vibrio parahaemolyticus
The quorum regulatory cascade is poorly characterized in Vibrio parahaemolyticus, in part because swarming and pathogenicity - the hallmark traits of the organism - are repressed by this scheme of gene control. As a consequence, many isolates appear silenced for quorum sensing via phase variation. I...

TranscriptomicsTranscriptional analysis of quorum sensing deficient in Yersinia pestis CO92 at 37M-BM-0C
Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of quorum sensing was investigated by comparing transcript profiles when three quorum-sensing synthase genes are knocked out....

TranscriptomicsTranscription analysis of AI-2 signal add in experiment in Yersinia pestis CO92 at 37M-BM-0C
Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of autoinducer-2 (AI-2) quorum sensing was investigated by comparing transcript profiles when AI-2 quorum-sensing signal is a...

TranscriptomicsA New Class of Homoserine Lactone Quorum Sensing Signals
Quorum sensing is a term used to describe cell-to-cell communication that allows cell density-dependent gene expression. Many Gram-negative bacteria use acyl-homoserine lactone (acyl-HSL) synthases to generate fatty acyl-HSL quorum sensing signals, which function with signal receptors to control exp...

TranscriptomicsAn antibody to Streptococcus pneumoniae capsular polysaccharide enhances quorum sensing
The primary mechanism by which pneumococcal capsular polysaccharide-based vaccines are believed to mediate protection is by induction of serotype-specific opsonic antibodies that facilitate bacterial killing by phagocytes (opsonophagocytosis). However, antibodies that are protective against experim...

TranscriptomicsRNA-Seq analysis of quorum sensing-dependent genes in Burkholderia glumae BGR1
Burkholderia glumae causes rice grain rot and sheath rot by producing toxoflavin, whose expression is regulated by quorum sensing (QS). The QS systems of the bacterium rely on N-octanoyl homoserine lactone, synthesized by TofI and its cognate receptor TofR, to activate toxoflavin biosynthesis genes ...
