Curli amyloid fibers in Escherichia coli biofilms: the influence of water availability on their structure and functional properties

bioRxiv, 2023
E. coli biofilms consist of bacteria embedded in a self-produced matrix mainly made of protein fibers and polysaccharides. The curli amyloid fibers found in the biofilm matrix are promising versatile building blocks to design sustainable bio-sourced ...

Salmonella Typhimurium resides largely as an extracellular pathogen in porcine tonsils, independently of biofilm-associated genes csgA, csgD and adrA [PDF]

, 2009
In European countries, Salmonella enterica subspecies enterica serovar Typhimurium (Salmonella Typhimurium) is the serovar most frequently isolated from slaughter pigs1.

Synthesis and patterning of tunable multiscale materials with engineered cells [PDF]

, 2013
Many natural biological systems - such as biofilms, shells and skeletal tissues - are able to assemble multifunctional and environmentally responsive multiscale assemblies of living and non-living components. Here, by using inducible genetic circuits and

Regulation of biofilm formation in Salmonella typhimurium and Escherichia coli Nissle 1917 [PDF]

, 2011
Bacteria have the ability to grow in cell communities designated biofilms. This mode of growth is widespread and offers numerous advantages to the bacteria in terms of survival, persistence and propagation.

Distribution of chaperone-usher fimbriae and curli fimbriae among uropathogenic Escherichia coli

BMC Microbiology
In the present study, we aimed to determine the frequency of the csgA, fimH, mrkD, foc, papaGI, papGII and papGIII genes, to provide and to design fimbrial adhesin gene (FAG) patterns and profiles for the isolated uropathogenic Escherichia coli (UPEC ...

Characterization of functional amyloid curli in biofilm formation of an environmental isolate Enterobacter cloacae SBP-8

Antonie van Leeuwenhoek, 2023
The biofilm formation by bacteria is a complex process that is strongly mediated by various genetic and environmental factors. Biofilms contribute to disease infestation, especially in chronic infections.

Diffusely adherent Escherichia coli strains isolated from children and adults constitute two different populations [PDF]

, 2013
Background: Diffusely adherent Escherichia coli (DAEC) have been considered a diarrheagenic category of E. coli for which several potential virulence factors have been described in the last few years.

Gene clusters reflecting macrodomain structure respond to nucleoid perturbations

, 2010
Focusing on the DNA-bridging nucleoid proteins Fis and H-NS, and integrating several independent experimental and bioinformatic data sources, we investigate the links between chromosomal spatial organization and global transcriptional regulation.

Small Regulatory RNAs in the Control of Motility and Biofilm Formation in E. coli and Salmonella [PDF]

, 2013
Biofilm formation in Escherichia coli and other enteric bacteria involves the inverse regulation of the synthesis of flagella and biofilm matrix components such as amyloid curli fibres, cellulose, colanic acid and poly-N-acetylglucosamine (PGA ...

Nitrate Is an Environmental Cue in the Gut for Salmonella enterica Serovar Typhimurium Biofilm Dispersal through Curli Repression and Flagellum Activation via Cyclic-di-GMP Signaling

mBio, 2022
Recent studies provided important insight into our understanding of the role of c-di-GMP signaling and the regulation of enteric biofilms. Despite an improved understanding of how c-di-GMP signaling regulates S.
