Escherichia coli, fimbriae, bacterial persistence and host response induction in the human urinary tract

International Journal of Medical Microbiology, 2005
Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine.

A short peptide derived from late embryogenesis abundant proteins enhances acid tolerance in Escherichia coli via modulation of two‐component regulatory systems

The FEBS Journal, Volume 293, Issue 3, Page 781-805, February 2026.
Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

The Interface of Oral and Brain Health: Current Insights Into the Bidirectional Relationship Between Alzheimer's Disease and Periodontitis

CNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.
Bidirectional Pathogenesis Between AD and Periodontitis. Periodontal pathogens reach the brain via hematogenous/trigeminal/oral–intestinal pathways, triggering neuroinflammation and Aβ plaques to drive AD. Conversely, AD disrupts bone homeostasis (via Aβ, endocrine/autonomic dysregulation) to aggravate periodontitis.

Type 3 fimbriae of Klebsiella sp.: molecular characterization and role in bacterial adhesion to plant roots [PDF]

Journal of Bacteriology, 1983
Type 3 fimbriae of Klebsiella were purified and characterized. The fimbriae were 4 to 5 nm in diameter and 0.5 to 2 microns long. In sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the fimbrillin had an apparent molecular weight of 23,500, and it differed from enterobacterial type 1 fimbrillins in its amino acid composition.
