Bacterial motility on a surface: many ways to a common goal.
TLDR
This review focuses mainly on surface motility and makes comparisons to features shared by other surface phenomenon.Abstract:
When free-living bacteria colonize biotic or abiotic surfaces, the resultant changes in physiology and morphology have important consequences on their growth, development, and survival. Surface motility, biofilm formation, fruiting body development, and host invasion are some of the manifestations of functional responses to surface colonization. Bacteria may sense the growth surface either directly through physical contact or indirectly by sensing the proximity of fellow bacteria. Extracellular signals that elicit new gene expression include autoinducers, amino acids, peptides, proteins, and carbohydrates. This review focuses mainly on surface motility and makes comparisons to features shared by other surface phenomenon.read more

Flagella-independent surface motility in Salmonella enterica serovar Typhimurium
TL;DR: A form of surface motility in the bacterium Salmonella enterica serovar Typhimurium that is activated in low Mg2+ by PhoP/PhoQ, a regulatory system that hinders flagella expression and activity is identified.

Inhibition of Pseudomonas aeruginosa Swarming Motility by 1-Naphthol and Other Bicyclic Compounds Bearing Hydroxyl Groups

TL;DR: It is shown that hydroxyindoles (4- and 5-hydroxyindoles) and naphthalene derivatives bearing hydroxyl groups specifically inhibit swarming motility but have minor effects on other motilities in P. aeruginosa.

TL;DR: Findings suggest that host cell function was actively regulated by plasmid carriage, and may have been responsible for the reduction in host fitness, motility and stress resistances.

The RNA chaperone, Hfq, controls two luxR-type regulators and plays a key role in pathogenesis and production of antibiotics in Serratia sp. ATCC 39006
Nabil M. Wilf,Neil R. Williamson,Joshua P. Ramsay,Simon Poulter,Kasia J. Bandyra,George P. C. Salmond +5 more
TL;DR: Using transcriptional fusions, it is suggested that an Hfq-dependent pathway is involved in the regulation of virulence and secondary metabolite production in ATCC 39006.
Journal ArticleDOI
Active depinning of bacterial droplets: The collective surfing of Bacillus subtilis.
TL;DR: It is shown that Bacillus subtilis can turn millimetric water droplets into vehicles to quickly cover large distances, and is uncovered, experimentally, a mode of collective bacterial motility in humid environment through the depinning of bacterial droplets.

Biofilm Formation as Microbial Development
TL;DR: The results reviewed in this article indicate that the formation of biofilms serves as a new model system for the study of microbial development.

Biofilms as complex differentiated communities.
TL;DR: It is submitted that complex cell-cell interactions within prokaryotic communities are an ancient characteristic, the development of which was facilitated by the localization of cells at surfaces, which may have provided the protective niche in which attached cells could create a localized homeostatic environment.

TL;DR: The isolation and characterization of mutants of Pseudomonas aeruginosa PA14 defective in the initiation of biofilm formation on an abiotic surface, polyvinylchloride (PVC) plastic are reported and evidence that microcolonies form by aggregation of cells present in the monolayer is presented.
