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

Caroline Aparecida Maggioni Fauro,Luanny Cristiny Moresco Tessari,Nohati Rhanda Freitas Dos Santos,Neocimar Saraiva Correia,Cibele Bonacorsi,Alexandre Melo Bailão,Lilian Cristiane Baeza,N. V. Verbisck,Fabiana Cristina Donofrio +8 more
TL;DR: It was showed that AMX, CLA, or TET at subinhibitory concentrations favors H. pylori motility and biofilm formation, which may have clinical consequences and make the microorganism difficult to eradicate.

García Calderón,Clara Beatriz +1 more
TL;DR: En el momento de iniciar esta tesis, trabajos recientes de nuestro laboratorio en colaboracion with el Dr. Garcia del Portillo habian descrito que alelos viables del gen esencial igaA activaban el sistema de transduccion de senales Rcs, y that dicha activacion atenuaba la virulencia de Salmonella.

Swarming Motility Assays in Salmonella.
TL;DR: In this paper , the authors describe protocols to cultivate, verify, and study swimming and swarming motility in S. enterica, and an additional "border-crossing" assay, where cells "primed" to swarm are presented with an environmental challenge such as antibiotics to assess their propensity to handle the challenge.

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.
