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

Mechanistic underpinning of nonuniform collective motions in swarming bacteria
TL;DR: In this article, the authors explore the collective dynamics of bacterial swarm subjected to a variation of cell-aspect ratio and find that at an intermediate aspect ratio, an optimum cell size and motility force promote alignment, which reinforces the mechanical interactions among neighboring cells leading to the overall fastest motion.

Studies on the Inter-Cellular Communication Mechanisms in the Rice Bacterial Pathogens Xanthomonas oryzae pv. oryzae and Pseudomonas fuscovaginae
TL;DR: It was concluded that OryR is not involved in bacterial QS but in inter-kingdom signalling by recognizing and responding to a molecule present in rice, and the Pfvl/R QS system was shown to be involved in virulence, to be important for the hypersensitivity response in non-host plants and for bacterial motility.

The action of phytochemicals in biofilm control.
TL;DR: The most relevant reports on the antibiofilm properties of phytochemicals, as well as insights into their structure and mechanistic action against bacterial pathogens, spanning December 2008 to December 2021, are presented in this paper .

The Hydrodynamics of a Rod-Shaped Squirmer near a Wall
TL;DR: In this paper , the hydrodynamic characteristics of a rod-shaped squirmer swimming near a wall were studied numerically using the immersed boundary-lattice Boltzmann method in the swimming Reynolds number range of 0.1 to 2.0.

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.
