Inversion-independent phase variation of type 1 fimbriae in Escherichia coli [PDF]

open access: yesJournal of Bacteriology, 1993
The roles of fimB and fimE in the phase-variable expression of type 1 fimbriae in Escherichia coli were examined. A method was developed to study the effects of fimB and fimE on both recombination of the fim invertible element and fimbrial expression. The method used an allelic exchange procedure consisting of two steps. The first step, construction of

EtcABC, a Putative EII Complex, Regulates Type 3 Fimbriae via CRP-cAMP Signaling in Klebsiella pneumoniae

open access: yesFrontiers in Microbiology, 2019
Biofilm formation by Klebsiella pneumoniae on indwelling medical devices increases the risk of infection. Both type 1 and type 3 fimbriae are important factors in biofilm formation by K. pneumoniae. We found that a putative enzyme II (EII) complex of the

Assembly of a chemically synthesized peptide of Escherichia coli type 1 fimbriae into fimbria-like antigenic structures [PDF]

open access: yesJournal of Bacteriology, 1987
Escherichia coli type 1 fimbriae are composed of subunits, each of which comprises 158 amino acids. We synthesized a copy of a 13-residue peptide, located near the NH2 terminus of the fimbrial subunit, that assumed some of the properties of type 1 fimbriae.

The Non-Fimbriate Phenotype Is Predominant among Salmonella enterica Serovar Choleraesuis from Swine and Those Non-Fimbriate Strains Possess Distinct Amino Acid Variations in FimH.

open access: yesPLoS ONE, 2016
Although most Salmonella serovars are able to infect a range of animal hosts, some have acquired the ability to cause systemic infections of specific hosts.

The KP1_4563 gene is regulated by the cAMP receptor protein and controls type 3 fimbrial function in Klebsiella pneumoniae NTUH-K2044. [PDF]

open access: yesPLoS ONE, 2017
Klebsiella pneumoniae (K. pneumoniae) is an opportunistic pathogen that can adhere to host cells or extracellular matrix via type 1 and type 3 fimbriae. KP1_4563 is a gene encoding a hypothetical protein in K. pneumoniae NTUH-K2044.

Identification of the long polar fimbriae gene variants in the locus of enterocyte effacement-negative Shiga toxin-producing Escherichia coli strains isolated from humans and cattle in Argentina [PDF]

open access: yes, 2010
The long polar fimbriae (Lpf) is one of few adhesive factors of Shiga toxin-producing Escherichia coli (STEC) and it is associated with colonization of the intestine. Studies have demonstrated the presence of lpf genes in several pathogenic E.

Short chain fatty acids induced the type 1 and type 2 fimbrillin-dependent and fimbrillin-independent initial attachment and colonization of Actinomyces oris monoculture but not coculture with streptococci

open access: yesBMC Microbiology, 2020
Background Actinomyces oris is an early colonizer and has two types of fimbriae on its cell surface, type 1 fimbriae (FimP and FimQ) and type 2 fimbriae (FimA and FimB), which contribute to the attachment and coaggregation with other bacteria and the ...

Identification of the genetic determinants of Salmonella enterica serotype Typhimurium that may regulate the expression of the type 1 fimbriae in response to solid agar and static broth culture conditions

open access: yesBMC Microbiology, 2008
Background Type 1 fimbriae are the most commonly found fimbrial appendages on the outer membrane of Salmonella enterica serotype Typhimurium. Previous investigations indicate that static broth culture favours S.

Duality of β-glucan microparticles: antigen carrier and immunostimulants [PDF]

open access: yes, 2016
Designing efficient recombinant mucosal vaccines against enteric diseases is still a major challenge. Mucosal delivery of recombinant vaccines requires encapsulation in potent immunostimulatory particles to induce an efficient immune response. This paper

Damping properties of type 1 fimbriae

open access: yes, 2014
Type 1 fimbriae mediate adhesion of uropathogenic Escherichia coli (UPEC) to host cells. It has been hypothesized that fimbriae can, by their ability to uncoil under exposure to force, reduce fluid shear stress on the adhesin-receptor interaction by which the bacterium adheres to the surface. In this work we develop a model that describes how the force
