Novel pili-like surface structures of Halobacterium salinarum strain R1 are crucial for surface adhesion

Frontiers in Microbiology, 2015
It was recently shown that haloarchaeal strains of different genera are able to adhere to surfaces and form surface-attached biofilms. However the surface structures mediating the adhesion were still unknown.

Production of pili, hemolysin and siderophores in the urinary isolates of Escherichia coli [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2013
Introduction. Escherichia coli (E. coli) are the most frequent cause of the urinary tract infections. Uropathogenic E. coli (UPEC) produce virulence factors which enable them to survive in the urinary tract and cause an infection. Objective.

Fabrication Routes for Ionic Conducting Fiber Strain Sensors

Advanced Engineering Materials, EarlyView.
Ionic conducting fiber strain sensors (ICFSs) offer compliant, textile‐integrable sensing. Thus far, the commercialization of ICFSs has been constrained by fiber fabrication routes. This review provides a fabrication‐centric analysis of ICFSs correlating processing strategies with material properties and scalability.

Nucleotide sequence of pilA, the gene encoding the structural component of type 1 pili in Escherichia coli [PDF]

Journal of Bacteriology, 1985
The pilA gene of Escherichia coli J96 encoding pilin, the structural component of type 1 pili, was sequenced and found to specify a polypeptide 159 amino acids long preceded by a 23-amino-acid signal peptide. As determined from the DNA sequence, the mature peptide lacked tryptophane and methionine, two amino acids previously shown to be lacking in type

Role of meprins to protect ileal mucosa of Crohn's disease patients from colonization by adherent-invasive E. coli. [PDF]

PLoS ONE, 2011
Ileal lesions in Crohn's disease (CD) patients are colonized by pathogenic adherent-invasive Escherichia coli (AIEC) able to adhere to and invade intestinal epithelial cells (IEC), and to survive within macrophages.

Hydrogels Augmented With Artificial Sweeteners can Inhibit Multidrug‐Resistant Acinetobacter baumannii Growth and Biofilm Formation While Demonstrating Safety in Pre‐Clinical Pilot Human Trials

Advanced Healthcare Materials, EarlyView.
Using PVA–borax hydrogels as carriers for off‐the‐shelf artificial sweeteners to fight multidrug‐resistant A. baumannii. These soft, biocompatible hydrogels rapidly reduce bacterial viability within multidrug‐resistant A. baumannii biofilms by more than 99% within one hour and sustain antimicrobial activity over time, while demonstrating safety in both

Optically Tunable Threshold Switching and Thermally Activated Transport in Planar Ag/MAPbI3 Thin Single‐Crystal Devices

Advanced Science, EarlyView.
Planar Ag/MAPbI3 thin single‐crystal halide perovskite devices show ultralow dark current and optically tunable threshold switching. Illumination enhances the polarity‐dependent hysteresis and shifts the switching voltage, whereas temperature‐dependent measurements reveal thermally activated, contact‐limited transport, underscoring the central role of ...

Evaluation of the role of Mycobacterium tuberculosis pili (MTP) as an adhesin, invasin, and cytokine inducer of epithelial cells

Brazilian Journal of Infectious Diseases, 2016
This study was undertaken in order to assess the involvement of Mycobacterium tuberculosis pili (MTP) as an adhesin, invasin, and cytokine inducer in the M. tuberculosis-epithelial cell interaction. A MTP-deficient strain of M.

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 ...

Control of pili synthesis and putrescine homeostasis in Escherichia coli

eLife
Polyamines are biologically ubiquitous cations that bind to nucleic acids, ribosomes, and phospholipids and, thereby, modulate numerous processes, including surface motility in Escherichia coli.
