Nanoscale Adhesion Forces of Pseudomonas aeruginosa Type IV Pili [PDF]
A variety of bacterial pathogens use nanoscale protein fibers called type IV pili to mediate cell adhesion, a primary step leading to infection. Currently, how these nanofibers respond to mechanical stimuli and how this response is used to control adhesion is poorly understood.

Electrochemical reduction of oxygen catalyzed by Pseudomonas aeruginosa [PDF]
Pseudomonas aeruginosa has already been shown to catalyze oxidation processes in the anode compartment of a microbial fuel cell. The present study focuses on the reverse capacity of the bacterium, i.e. reduction catalysis. Here we show that P. aeruginosa

Cryo-electron microscopy reveals two distinct type IV pili assembled by the same bacterium
Type IV pili are flexible filaments on the surface of bacteria, consisting of a helical assembly of pilin proteins. Here, Neuhaus et al. show that the bacterium Thermus thermophilus produces two forms of type IV pilus, differing in structure, protein ...

Identification of surprisingly diverse type IV pili, across a broad range of gram-positive bacteria. [PDF]
In Gram-negative bacteria, type IV pili (TFP) have long been known to play important roles in such diverse biological phenomena as surface adhesion, motility, and DNA transfer, with significant consequences for pathogenicity.

Structure and function of minor pilins of type IV pili. [PDF]
AbstractType IV pili are versatile and highly flexible fibers formed on the surface of many Gram-negative and Gram-positive bacteria. Virulence and infection rate of several pathogenic bacteria, such as Neisseria meningitidis and Pseudomonas aeruginosa, are strongly dependent on the presence of pili as they facilitate the adhesion of the bacteria to ...

The role of bacterial secretion systems in the virulence of Gram-negative airway pathogens associated with cystic fibrosis [PDF]
Cystic fibrosis (CF) is the most common lethal inherited disorder in Caucasians. It is caused by mutation of the CF transmembrane conductance regulator (CFTR) gene.
