Production of Cellulose and Curli Fimbriae by Members of the Family Enterobacteriaceae Isolated from the Human Gastrointestinal Tract
Open accessAbstract
Citrobacter spp., Enterobacter spp., and Klebsiella spp. isolated from the human gut were investigated for the biosynthesis of cellulose and curli fimbriae ( csg ). While Citrobacter spp. produced curli fimbriae and cellulose and Enterobacter spp. produced cellulose with various temperature-regulatory programs, Klebsiella spp. did not show pronounced expression of those extracellular matrix components. Investigation of multicellular behavior in two Citrobacter species and Enterobacter sakazakii showed an extracellular matrix, cell clumping, pellicle formation, and biofilm formation associated with the expression of cellulose and curli fimbriae. In those three strains, the csgD-csgBA region and the cellulose synthase gene bcsA were conserved. PCR screening for the presence of csgD, csgA and bcsA revealed that besides Klebsiella pneumoniae and Klebsiella oxytoca, all species investigated harbored the genetic information for expression of curli fimbriae and cellulose. Since Citrobacter spp., Enterobacter spp., and Klebsiella spp. are frequently found to cause biofilm-related infections such as catheter-associated urinary tract infections, the human gut could serve as a reservoir for dissemination of biofilm-forming isolates.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
