Biofilm Formation and Motility Are Promoted by Cj0588-Directed Methylation of rRNA in Campylobacter jejuni

Frontiers in Cellular and Infection Microbiology, 2018
Numerous bacterial pathogens express an ortholog of the enzyme TlyA, which is an rRNA 2′-O-methyltransferase associated with resistance to cyclic peptide antibiotics such as capreomycin.

The prevalence of motility-related genes within the human oral microbiota

Microbiology Spectrum
The human oral and nasal microbiota contains approximately 770 cultivable bacterial species. More than 2,000 genome sequences of these bacteria can be found in the expanded Human Oral Microbiome Database (eHOMD).

ArgR regulates motility and virulence through positive control of flagellar genes and inhibition of diguanylate cyclase expression in Aeromonas veronii

Communications Biology
Flagella are essential for biofilm formation, adhesion, virulence, and motility. In this study, the deletion of argR resulted in defects in flagellar synthesis and reduced motility, nevertheless, the underlying mechanism by which ArgR regulated bacterial

Flagellum-driven motility enhances Pseudomonas aeruginosa biofilm formation by altering cell orientation

Applied and Environmental Microbiology
Bacterial motility plays a crucial role in biofilm development, yet the underlying mechanism remains not fully understood. Here, we demonstrate that the flagellum-driven motility of Pseudomonas aeruginosa enhances biofilm formation by altering the ...

The cyclic di-GMP receptor YcgR links the second messenger with the putrescine quorum sensing system in modulation of Dickeya oryzae motility

mBio
Dickeya oryzae is a prevalent pathogen capable of infecting a variety of crops and plants, and its cell motility plays a key role in invasion of host and subsequent systemic infection. We recently demonstrated that the bacterial second messenger c-di-GMP

LIPI-4 and lmo0180 cooperatively regulate flagellar motility and virulence in Listeria monocytogenes

Frontiers in Cellular and Infection Microbiology
IntroductionDeletion of Listeria pathogenicity island 4 (LIPI-4) in Listeria monocytogenes (L. monocytogenes) impairs motility, disrupts flagellar assembly, and markedly upregulates the lmo0180 gene.MethodsIn this study, the Δlmo0180 single-gene deletion

The Small Molecule Inhibitor of the Type III Secretion System Fluorothiazinone Affects Flagellum Surface Presentation and Restricts Motility in Gram-Negative Bacteria

Antibiotics
Background/Objectives: Fluorothiazinone (FT), a small molecule of the 2,4-disubstituted-4H-[1,3,4]-thiadiazine-5-one class, is known to inhibit the type III secretion system (T3SS) in Gram-negative bacteria and has shown therapeutic potential in animal ...

Torque-speed relationship of the flagellar motor with dual-stator systems in Pseudomonas aeruginosa

mBio
The single polar flagellar motor in Pseudomonas aeruginosa is equipped with two stator systems, MotAB and MotCD, both driven by H+ ions. The torque-speed relationship for flagellar motors with two stator systems has not been explored previously.
