Integrin-mediated host cell invasion by type 1-piliated uropathogenic Escherichia coli.

PLoS Pathogens, 2007
Uropathogenic Escherichia coli (UPEC), the primary causative agent of urinary tract infections, typically express filamentous adhesive organelles called type 1 pili that mediate both bacterial attachment to and invasion of bladder urothelial cells ...

The pilin protein FimP from Actinomyces oris: crystal structure and sequence analyses. [PDF]

PLoS ONE, 2012
The Actinomyces oris type-1 pili are important for the initial formation of dental plaque by binding to salivary proteins that adhere to the tooth surface. Here we present the X-ray structure of FimP, the protein that is polymerized into the type-1 pilus

Specific involvement of pilus type 2a in biofilm formation in group B Streptococcus. [PDF]

PLoS ONE, 2010
Streptococcus agalactiae is the primary colonizer of the anogenital mucosa of up to 30% of healthy women and can infect newborns during delivery and cause severe sepsis and meningitis. Persistent colonization usually involves the formation of biofilm and

Comprehensive Identification of Fim-Mediated Inversions in Uropathogenic Escherichia coli with Structural Variation Detection Using Relative Entropy

mSphere, 2019
Most urinary tract infections (UTIs) are caused by uropathogenic Escherichia coli (UPEC), which depends on an extracellular organelle (type 1 pili) for adherence to bladder cells during infection.

Escherichia coli Biofilm Formation, Motion and Protein Patterns on Hyaluronic Acid and Polydimethylsiloxane Depend on Surface Stiffness

Journal of Functional Biomaterials, 2022
The surface stiffness of the microenvironment is a mechanical signal regulating biofilm growth without the risks associated with the use of bioactive agents.

Safety and immunogenicity of an adjuvanted Escherichia coli adhesin vaccine in healthy women with and without histories of recurrent urinary tract infections: results from a first-in-human phase 1 study

Human Vaccines & Immunotherapeutics, 2021
Antibiotic resistance among gram-negative bacteria continues to rise globally at an alarming rate. New vaccines that prevent bacterial infections and reduce antibiotic use could provide a potential solution to these problems.

Mucosal fluid glycoprotein DMBT1 suppresses twitching motility and virulence of the opportunistic pathogen Pseudomonas aeruginosa. [PDF]

PLoS Pathogens, 2017
It is generally thought that mucosal fluids protect underlying epithelial surfaces against opportunistic infection via their antimicrobial activity.

Regulation of Type 1 Pili Expression as Exemplified by Escherichia Coli Strain M17

Bulletin of Experimental Biology and Medicine, 2001
Studies of E. coli strain M17 colibacterin and its derivatives showed that fimH gene regulates morphological characteristics of type 1 fimbria and cell piliation on the whole. Gene fimH has a negative effect and decreased the percentage of piliated cells in the population and piliation of individual cells, which does not agree with its role of a ...

FimH adhesin of type 1 pili is assembled into a fibrillar tip structure in the Enterobacteriaceae. [PDF]

Proceedings of the National Academy of Sciences, 1995
Type 1 pili are heteropolymeric mannosebinding fibers produced by all members of the Enterobacteriaceae family. The bulk of the fiber is composed of FimA. Two macromolecular complexes responsible for mediating an interaction with mannose-containing receptors were purified from fimA- Escherichia coli by mannose affinity chromatography and ion-exchange ...

Immunoglobulin A and secretory immunoglobulin A antibodies to purified type 1 Klebsiella pneumoniae pili in human colostrum [PDF]

Infection and Immunity, 1982
Immunoglobulin A antibodies with binding specificity for purified Klebsiella pneumoniae type 1 pili were detected by an enzyme-linked immunosorbent assay in 20 of 21 human samples (95%). The concentrations of secretory immunoglobulin A antibody in colostrum directed against the pili were calculated by comparison of experimental enzyme-linked ...
