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

Development of an integrated optical analyzer for characterization of growth dynamics of bacterial colonies.
TL;DR: In order to understand the biophysics behind collective behavior of a bacterial colony, a confocal displacement meter was used to measure the profiles of the bacterial colonies, together with a custom built optical density circuits.

Staphylococcus aureus and Pseudomonas aeruginosa express and secrete human surfactant proteins
TL;DR: The results strongly suggest that the bacteria are either able to express ‘human-like’ surfactant proteins on their own or that commercially available primers and antibodies to human surfACTant proteins detect identical bacterial proteins and genes.

Inhibition of the pqsABCDE and pqsH in the pqs quorum sensing system and related virulence factors of the Pseudomonas aeruginosa PAO1 strain by farnesol
TL;DR: It is concluded that farnesol can suppress the virulence by inactivating the pqs QS system in pathogen P. aeruginosa, which would be significant to develop a kind of effective drug control the virulent and pathogenesis of this bacteria.

TL;DR: It is suggested that surface adsorption of naphthalene can mediate the relative importance of advective chemotaxis (facilitating initial breakthrough), near-surface chemoattractants in mobile liquids and along immobile surfaces, and haptOTaxis (increasing bacterial residence time).

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.
