Microbial Primer: Agr-mediated quorum sensing in Gram-positive pathogens

Gram-positive bacteria commonly employ autoinducing peptide (AIP) signal molecules to co-ordinate gene expression at the population level. This primer provides a basic overview of agr-dependent quorum sensing systems and outlines how AIPs are produced ...

Synergy and Group Size in Microbial Cooperation [PDF]

, 2012
Microbes produce many molecules that are important for their growth and development, and the exploitation of these secretions by nonproducers has recently become an important paradigm in microbial social evolution. Although the production of these public-

Biofilm Exoproteins From Staphylococcus Species Impede Re‐Epithelialization of Nasal Epithelial Cells During Wound Healing and Cease Ciliary Beat Frequency

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Chronic rhinosinusitis (CRS) is an inflammatory disease with many different contributing factors, including bacterial infection. CRS patients are typically managed with medical therapies; however, these treatments frequently fail, leaving surgery as the only viable option.

Unveiling bacterial communication with a MATLAB GUI implementing the diffusion-based quorum sensing model

Scientific Reports
Bacteria employ quorum sensing as a remarkable mechanism for coordinating behaviors and communicating within their communities. In this study, we introduce a MATLAB Graphical User Interface (GUI) that offers a versatile platform for exploring the ...

Plant-Derived Natural Products as Sources of Anti-Quorum Sensing Compounds

Sensors, 2013
Quorum sensing is a system of stimuli and responses in relation to bacterial cell population density that regulates gene expression, including virulence determinants. Consequently, quorum sensing has been an attractive target for the development of novel

Interspecies Biofilm Dynamics Among Staphylococci: Inflammatory Contributions to Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Staphylococcus species are frequently isolated from the sinonasal niche of chronic rhinosinusitis (CRS) patients. While Staphylococcus aureus is often associated with recalcitrant CRS, Staphylococcus epidermidis and Staphylococcus lugdunensis are largely deemed commensal.

Female‐Specific Risk of TAS2R Variants in Chronic Rhinosinusitis: A Hospital‐Based Cohort Study From the Taiwan Precision Medicine Initiative

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Bitter taste receptors (T2Rs) function in the innate immune defense of the sinonasal mucosa; however, the genetic association between the TAS2R gene family and chronic rhinosinusitis (CRS) remains understudied in Asian populations.

β-Sitosterol derived compound from onion husks non-polar fraction reduces quorum sensing controlled virulence and biofilm production

Saudi Pharmaceutical Journal, 2019
Quorum sensing is an important regulatory factor of P. aeruginosa virulence induction such as BF, motility, formations of proteases, pyocyanin, and some toxins. The aim of the current study is to detect the effect of the pet.ether extract from onion husk

Mutation rate plasticity in rifampicin resistance depends on Escherichia coli cell–cell interactions [PDF]

, 2014
Variation of mutation rate at a particular site in a particular genotype, in other words mutation rate plasticity (MRP), can be caused by stress or ageing. However, mutation rate control by other factors is less well characterized.

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...
