Mutations in the csgD promoter associated with variations in curli
expression in certain strains of Escherichia coli O157:H7.
Two types of swarming motility pathways, namely type I and curli
pilin, were identified in this genome.
Biofilm formation by Escherichia coli O157:H7 on stainless steel: effect of exopolysaccharide and curli
production on its resistance to chlorine.
For instance, at Norwood (KOWD) [shown right], the fixes CURLI
, CUPUG and FIGOL would become OWD030, OWD017 and OWD006.
These findings contrast other studies that have associated curli
pili as inducers of the immune system.
Role of Escherichia coli curli
operons in directing amyloid fiber formation," Science, vol.
are functional amyloid fibers that constitute the major protein component of the extracellular matrix in pellicle biofilms formed by Bacteroidetes and Proteobacteria.
20) On the gender trouble generated by war, see Curli
and Di Cori.
qRT-PCR was used to investigate the transcription levels of curli
genes (csgA and csgB), motility genes [flhD and motB), Shiga-like toxin genes (stxl and stx2), and quorum-sensing genes (IsrA and luxS) in E.
Lu and his colleagues worked with the bacterium Escherichia coli because it naturally produces biofilms that contain so-called curli
fibers--amyloid proteins that help E.
Production of cellulose and curli
fimbriae by members of the family Enterobacteriaceae isolated from the human gastrointestinal tract.
This puts control of curli
fiber production in the hands of the researchers, who can adjust the amount of AHL in the cells' environment.
