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

The inhibition of Pseudomonas aeruginosa by manuka honey
TL;DR: In vitro studies confirm that manuka honey inhibits both planktonic and sessile (biofilm) P. aeruginosa cells through the differential regulation of key genes required for cell envelope stability and motility.

Surface migration of Staphylococcus xylosus on low-agar media.
TL;DR: It is shown that the majority of S. xylosus strains also exhibit extensive colony spreading on the surface of soft agar media, indicating that extracellular DNA may be involved in limiting the phenomenon.
The evolution of bacterial cell differentiation and multicellular organization
TL;DR: In this paper, a combinatie van experimenten and theorie is presented to show how simplistisch the kijk op bacterien is, and how cellen evolueren over time.

Atypical Salmonella enterica Serovars in Murine and Human Macrophage Infection Models
Daniel Hurley,Maria Hoffmann,Tim Muruvanda,Marc W. Allard,Eric W. Brown,Marta Martins,Séamus Fanning +6 more
TL;DR: The virulence characteristics and genomes of 10 atypical S. enterica serovars linked to multistate foodborne outbreaks in the United States are reported, showing that the murine RAW 264.7 macrophage model of infection is unsuitable for inferring human-relevant differences in nontyphoidal Salmonella infections, whereas differentiated human THP-1 macrophages allowed these isolates to be further characterized in a more human- relevant context.
Biodegradation of cyanobacterial hepatotoxins [Dha⁷]MC-LR and MC-LR by natural aquatic bacteria.
TL;DR: It was suggested that the degradation of DhaMC-LR and MC-LR by the Sphingomonas isolate NV-3 occurred by a similar mechanism previously described for Sphingmonas strain MJ-PV (ACM-3962).

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.
