Distinct mutations led to inactivation of type 1 fimbriae expression in Shigella spp. [PDF]

PLoS ONE, 2015
Shigella spp. are responsible for bacillary dysentery in humans. The acquisition or the modification of the virulence plasmid encoding factors promoting entry of bacteria into and dissemination within epithelial cells was a critical step in the evolution

Arginine within a specific motif near the N‐terminal of FimY is critical for the maximal production of type 1 fimbriae in Salmonella enterica serovar Typhimurium [PDF]

MicrobiologyOpen, 2019
An important Salmonella serovar for both human and animals Salmonella Typhimurium possesses 13 gene clusters that have the potential to produce fimbrial structure, among which the type 1 fimbriae with the binding specificity to mannose residue is the ...

Role of the stress-responsive two-component system CpxAR in regulating fimbriae expression in Klebsiella pneumoniae CG43

Journal of Microbiology, Immunology and Infection, 2023
Background: CpxAR is a two-component system that allows bacteria to reorganize envelope structures in response to extracellular stimuli. CpxAR negatively affects type 1 fimbriae expression in Klebsiella pneumoniae CG43, a hypervirulent strain.

Pre-Growth Culture Conditions Affect Type 1 Fimbriae-Dependent Adhesion of Salmonella. [PDF]

Int J Mol Sci, 2020
Among various fimbrial structures used by Salmonella enterica to colonize host tissues, type 1 fimbriae (T1F) are among the most extensively studied. Although some experiments have shown the importance of T1F in the initial stages of Salmonella infection, their exact role in the infection process is not fully known. We suggested that different outcomes

Type 1 fimbriae of Salmonella enteritidis [PDF]

Journal of Bacteriology, 1991
Salmonella enteritidis was previously shown to produce fimbriae composed of 14,000-molecular-weight (Mr) fimbrin monomers (J. Feutrier, W. W. Kay, and T. J. Trust, J. Bacteriol. 168:221-227, 1986). Another distinct fimbrial structure, comprising 21,000-Mr fimbrin monomers, has now been identified.

The role of urease in the acid stress response and fimbriae expression in Klebsiella pneumoniae CG43

Journal of Microbiology, Immunology and Infection, 2022
Background/purpose: Two urease operons were identified in Klebsiella pneumoniae CG43, ure-1 and ure-2. This study investigates whether a differential regulation of the expression of ure-1 and ure-2 exists and how urease activity influences the acid ...

Antigens Of The Type-2 Fimbriae Of Salmonellae: "Cross-Reacting Material" (Crm) Of Type-1 Fimbriae [PDF]

Journal of Medical Microbiology, 1971
Summary Antisera were prepared against the type-1 fimbriae of three strains of Salmonella paratyphi B and against the type-2 fimbriae of two strains of S. paratyphi B and one strain of S. pullorum. The anti-type-1 and anti-type-2 sera agglutinated fimbriate-phase bacteria possessing either type-1 or type-2 fimbriae.
