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

Mechanics of swimming of multi-body bacterial swarmers using non-labeled cell tracking algorithm
Kiran Phuyal,Min Jun Kim +1 more
TL;DR: A non-labeled cell tracking algorithm was used to quantify the mechanics of multi-body flagellated bacteria, Serratia marcescens, swimming in a motility buffer that originally exhibited the swarming motility.

Modeling the role of water in Bacillus subtilis colonies.
TL;DR: It is shown that it is possible to reproduce in a fairly satisfactory way the various forms that make up the experimentally observed morphological diagram of B. subtilis.

Bacteria in Fluid Flow
Gilberto C. Padron,Alexander M. Shuppara,Jessica Palalay,Anuradha Sharma,Joseph E. Sanfilippo +4 more
TL;DR: In this paper , the authors highlight the wide range of bacterial responses to flow, including changes in surface adhesion, motility, surface colonization, quorum sensing, virulence factor production, and gene expression.

Quenching a swarm: Effect of light exposure on suppression of collective motility in swarming Serratia marcescens
TL;DR: The immobilization and quenching of large-scale flows when the moving swarm is exposed to light with a substantial ultra-violet component is studied and a minimal Brownian dynamics model is proposed to examine the escape of exposed bacteria from the region of exposure.

Broad-spectrum adaptive antibiotic resistance associated with Pseudomonas aeruginosa mucin-dependent surfing motility
TL;DR: It is proposed that surfing adaption led to extensive multidrug adaptive resistance as a result of the collective dysregulation of diverse genes.

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.

Flagellar and twitching motility are necessary for Pseudomonas aeruginosa biofilm development
George A. O'Toole,Roberto Kolter +1 more
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.
