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

TL;DR: The modifications of materials used to develop innovative cell culture systems for controlling cell adhesion, migration, proliferation, and differentiation, as well as for achieving cocultures or three-dimensional cultures are described.

The propagation of active-passive interfaces in bacterial swarms
TL;DR: This work uses ultra-violet light exposure to create compact domains of passive bacteria within Serratia marcescens swarms, thereby creating interfaces separating motile and immotile cells, and demonstrates that the active-passive boundary acts as a diffuse interface with mechanical properties set by the flow.
Genetics and physiology of motility by Photorhabdus spp
TL;DR: The ability of Photorhabdus to swarm could provide a rapid and coordinated colonization of either nematode or insect host, or in traveling from one host to another, for an organism that must adapt quickly to changing environments.

Understanding the Role of Anaerobic Respiration in Burkholderia Thailandensis and B. pseudomallei Survival and Virulence
TL;DR: The importance of anaerobic respiration in the survival of B. pseudomallei has been highlighted and an in-frame narG deletion mutant was created in B. thailandensis moeA transposon mutant, which was unable to respire anaerobically on nitrate, but did not affect virulence in Galleria mellonella.

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.
