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

Cyclic di-GMP interact with putrescine via a PilZ domain receptor YcgR
TL;DR: In this article , the second messenger c-di-GMP and putrescine mediated quorum sensing (QS) system are both involved in the regulation of the bacterial motility in Dickea oryzea EC1.

Characterization of a mucoid-like Pseudomonas aeruginosa biofilm
Brandon M. Bauer,Lewis Rogers,Monique Macias,Gabriella Iacovetti,Alexander M. Woodrow,Melissa J. Labonte-Wilson,Kathleen G. Tallman +6 more
TL;DR: In this paper, two types of Pseudomonas aeruginosa biofilms, a non-mucoid and a mucoid-like phenotype, were found to have a significant increase in twitching between 24 and 72 hours of development.

Efflux pumps and microbial biofilm formation.
TL;DR: In this article , the role of efflux pumps in biofilm-related infections was analyzed based on efflux pump expression analysis, and their role in the anatomical position within the biofilm will differ depending on the biofiltering stage, encoding gene expression level, the type and concentration of substrate.

FliW and CsrA govern flagellin (FliC) synthesis and play pleiotropic roles in virulence and physiology of Clostridioides difficile R20291
TL;DR: In this article, the authors characterized FliW and CsrA functions by deleting or overexpressing fliW, csrA, and fliC-csrA in C. difficile R20291.

Quorum Sensing in Bacteria
TL;DR: The evolution of quorum sensing systems in bacteria could, therefore, have been one of the early steps in the development of multicellularity.

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.
