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: In this article, Tobramycin (TB), an aminoglycoside antibiotic that displays several undesirable side effects, has been encapsulated into cationic Eudragit®E100 (E100) NPs for the treatment of infections caused by Pseudomonas aeruginosa.
Dissertation
Ecological and evolutionary implications of shapes during population expansion
TL;DR: This chapter measures the rate of radial spatial spread of biofilms consisting of the Pseudomonas fluorescens SBW25 WS and SM morphologies on different viscosity agars and classify the rates as either constant, accelerating or decelerating, highlighting the unreliability of the constant rate of spread prediction.
Journal Article
12-Methyltetradecanoic acid, a branched-chain fatty acid, represses the extracellular production of surfactants required for swarming motility in Pseudomonas aeruginosa PAO1.
TL;DR: It is indicated that 12-MTA reduced extracellular surfactant activity, thus resulting in a swarming defect in P. aeruginosa PAO1.

Paeonol Interferes With Quorum-Sensing in Pseudomonas aeruginosa and Modulates Inflammatory Responses In Vitro and In Vivo
Huaqiao Tang,Dan Yang,Ling Zhu,Fei Shi,Gang Ye,Hongrui Guo,Huidan Deng,Lin Zhao,Zhi Wen Xu,Yinglun Li +9 more
TL;DR: Paeonol can inhibit the virulence of P.aeruginosa infection and enhance the ability of macrophages to clear bacteria, which supports the further development of new potential anti-infective drugs based on inhibition of QS and virulence factors.

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.
