Characterization of pili protein with molecular mass of 85 kDa Escherichia coli as an adhesin and a hemagglutinin

open access: yesJKKI (Jurnal Kedokteran dan Kesehatan Indonesia), 2020
Background: Escherichia coli (E. coli) is a rod-shaped gram-negative bacterium included in Multi Drug Resistant (MDR) bacteria. There are several strategies in place to prevent and treat E.

Pseudomonas aeruginosa orchestrates twitching motility by sequential control of type IV pili movements

open access: yesNature Microbiology, 2019
Prokaryotes have the ability to walk on surfaces using type IV pili (TFP), a motility mechanism known as twitching1,2. Molecular motors drive TFP extension and retraction, but whether and how these movements are coordinated is unknown3.

The structures of two archaeal type IV pili illuminate evolutionary relationships

open access: yesNature Communications, 2020
We have determined the cryo-electron microscopic (cryo-EM) structures of two archaeal type IV pili (T4P), from Pyrobaculum arsenaticum and Saccharolobus solfataricus , at 3.8 Å and 3.4 Å resolution, respectively.

Mutations in the gene encoding the ancillary pilin subunit of the Streptococcus suis srtF cluster result in pili formed by the major subunit only. [PDF]

open access: yesPLoS ONE, 2010
Pili have been shown to contribute to the virulence of different Gram-positive pathogenic species. Among other critical steps of bacterial pathogenesis, these structures participate in adherence to host cells, colonization and systemic virulence ...

Retraction of DNA-bound type IV competence pili initiates DNA uptake during natural transformation in Vibrio cholerae

open access: yesNature Microbiology, 2018
Natural transformation is a broadly conserved mechanism of horizontal gene transfer in bacterial species that can shape evolution and foster the spread of antibiotic resistance determinants, promote antigenic variation and lead to the acquisition of ...

Electromicrobiology: Electron Transfer via Biowires in Nature and Practical Applications

open access: yesBIO Web of Conferences, 2016
One of the most exciting developments in the field of electromicrobiology has been the discovery of electrically conductive pili (e-pili) in Geobacter species that transport electrons with a metallic-like mechanism.

Testing And evaluation of biomass roasting furnace using Pili Shell

open access: yesDiversitas Journal, 2023
The use of pili shells as fuel in a biomass roasting furnace for roasting meat was investigated in this study. To estimate the capacity of pili shells in roasting meat, researchers used observation, experimentation, data analysis, and interpretation ...

Pathogenesis of pili annulati [PDF]

open access: yesArchives of Dermatological Research, 1988
Plucked scalp hairs and hair roots of pili annulati were examined to understand their pathogenesis. Stereoscopic examinations of hairs in transmitted light and/or reflected light and light microscopic surveys of the cross-sections of hairs confirmed that the cortical empty spaces appeared to be responsible to the unique dotted shiny appearance of the ...

Retraction of F Pili [PDF]

open access: yesJournal of Bacteriology, 1974
The disappearance of F pili on Escherichia coli cells in the presence of 10 −2 M NaCN was studied by electron microscopy and serum-blocking power. The pili which disappeared from the cell did not appear as free pili in the culture medium, suggesting that the pili had retracted into the cell ...

Surface structures involved in plant stomata and leaf colonization by Shiga-toxigenic Escherichia coli O157:H7

open access: yesFrontiers in Cellular and Infection Microbiology, 2011
Shiga-toxigenic Escherichia coli (STEC) O157:H7 uses a myriad of surface adhesive appendages including pili, flagella, and the type 3 secretion system (T3SS) to adhere to and inflict damage to the human gut mucosa. Consumption of contaminated ground beef,
