Bacterial Adhesion Pili

open access: yesSub-cellular biochemistry, 2018
Escherichia coli bacterial cells produce multiple types of adhesion pili that mediate cell-cell and cell-host attachments. These pili (also called 'fimbriae') are large biopolymers that are comprised of subunits assembled via a sophisticated micro-machinery into helix-like structures that are anchored in the bacterial outer membrane.

Accelerated Microbial Corrosion by Magnetite and Electrically Conductive Pili through Direct Fe0‐to‐Microbe Electron Transfer

Angewandte Chemie - International Edition, 2023
Electrobiocorrosion, the process in which microbes extract electrons from metallic iron (Fe0) through direct Fe0-microbe electrical connections, is thought to contribute to the costly corrosion of iron-containing metals that impacts many industries ...

Biogenesis of Type V pili

open access: yesMicrobiology and Immunology, 2020
Pili or fimbriae, which are filamentous structures present on the surface of bacteria, were purified from a periodontal pathogen, Porphyromonas gingivalis, in 1980s.

Pili for nanowires

Nature Microbiology, 2021
Extracellular electron transport in Geobacter has long been ascribed to conductive pili. Cryogenic electron microscopy now reveals non-conductive filaments made of pilin-heterodimer subunits. The combined data support a role for Geobacter pili in cytochrome-nanowire secretion instead of conduction.

Pili Annulati*

Australasian Journal of Dermatology, 1970
SUMMARYThe chance seeing of a case of pili annulati provided an occasion for reviewing the salient features of this condition. Previous observation that the abnormal areas disappear after exposure to weak alkali on a glass microscopic slide was confirmed.Electron microscopic examination of hair samples from the young man and his elder sister suggests ...

Quantitation by ELISA of pili and sheep antibodies to the pili of Bacteroides nodosus

Australian Veterinary Journal, 1983
SUMMARY ELISA systems have been developed to quantitate the isotypic antibody response of sheep naturally infected with B. nodosus isolate 198 or injected with pili from isolate 198 in oil emulsion vaccines. The predominant humoral antibody detected following vaccination was IgG, with substantially lower amounts of IgG2 and IgM.
