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

Swarming motility in Bradyrhizobium japonicum
TL;DR: In sterile soil at 100% or 80% field capacity, flagellar-driven motility of mutants able to swim but impaired in swarming was similar to wild type, indicating that swimming was the predominant movement here.

Swimming performance of Bradyrhizobium diazoefficiens is an emergent property of its two flagellar systems

TL;DR: Each flagellum seemed engaged in a particular task that might be required for swimming oriented toward chemoattractants near the soil inner surfaces at viscosities that may occur after the loss of soil gravitational water.
Journal ArticleDOI
Self-organization of swimmers drives long-range fluid transport in bacterial colonies.
TL;DR: It is shown that motile cells in sessile colonies of peritrichously flagellated bacteria can self-organize into two adjacent, centimeter-scale motile rings surrounding the entire colony, providing a stable and high-speed avenue for directed material transport at the macroscopic scale.

Pathogenesis of Proteus mirabilis in Catheter-Associated Urinary Tract Infections.
TL;DR: Proteus mirabilis (PM) is a Gram-negative rod-shaped bacterium and widely exists in the natural environment, and it is most noted for its swarming motility and urease activity as mentioned in this paper.

Streptomycin mediated biofilm inhibition and suppression of virulence properties in Pseudomonas aeruginosa PAO1
Fazlurrahman Khan,Jang-Won Lee,Dung Thuy Nguyen Pham,Jae-Hwa Lee,Hyun-Woo Kim,Yeon-Kye Kim,Young-Mog Kim +6 more
TL;DR: The present study showed that the sub-minimum inhibitory concentration (sub-MIC) of streptomycin inhibited the formation of biofilm and eradicated the established mature biofilm in Pseudomonas aeruginosa.

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.
