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

Characterization of surface motility in Sinorhizobium meliloti : regulation and role in symbiosis
TL;DR: The symbiotic phenotypes shown by GR4flaAB andGR4flgK, non-flagellated mutants with opposite surface motility behavior, demonstrate that flagella-dependent motility positively influences competitiveness for nodule occupation, but is not crucial for optimal infectivity.

Bacterial Acrobatics on a Surface: Swirling Packs, Collisions, and Reversals during Swarming
TL;DR: Swarming is a particular type of motility that is promoted by flagella and allows bacteria to move rapidly over and between surfaces and through viscous environments.

Naked Bacterium: Emerging Properties of a Surfome-Streamlined Pseudomonas putida Strain.
Esteban Martínez-García,Sofía Fraile,David R. Espeso,Davide Vecchietti,Giovanni Bertoni,Víctor de Lorenzo +5 more
TL;DR: The editing of the genome of Pseudomonas putida KT2440 was reported for stripping the cells of most outer-facing structures of the bacterial envelope that mediate motion, binding to surfaces and biofilm formation, resulting in the surface-naked strain EM371, the physical properties of which changed dramatically in respect to the wild type counterpart.

Three-dimensional swimming motility of microorganism in the near-wall region
TL;DR: In this article, the effects of the interaction between the microorganism and a solid wall on the 3D swimming characteristics, such as helix parameters, orientation, and attraction to the wall, are experimentally analyzed.

Swarming motility by Photorhabdus temperata is influenced by environmental conditions and uses the same flagella as that used in swimming motilityThis is scientific contribution No. 2431 from the New Hampshire Agricultural Experiment Station.
TL;DR: Photorhabdus temperata, an insect pathogen and nematode symbiont, is motile in liquid medium by swimming but was found to be capable of surface movement, termed swarming behavior, and use the same flagella for both swimming and swarming motility.

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.

Flagellar and twitching motility are necessary for Pseudomonas aeruginosa biofilm development

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.
