PapB Family Regulators as Master Switches of Fimbrial Expression [PDF]

Microorganisms
Some bacterial species within the Enterobacteriaceae family possess different types of fimbrial (pili) adhesins that promote adherence to cells and colonization of host tissues.

Bacterial fimbriae designed to stay with the flow. [PDF]

PLoS Biology, 2006
The human digestive system houses a diverse colony of beneficial bacteria, but one species—E. coli—can wreak havoc when it colonizes mucous membranes that normally exist unmolested (for example, in the urinary tract). To latch on to cells and establish infection, E. coli uses fimbriae—long, hairlike organelles that project from the bacterium’s surface.

Macrophage activation and invasion by P. gingivalis is modulated by PPAD and accessory fimbriae subunits [PDF]

Journal of Oral Microbiology
Background Porphyromonas gingivalis is a master manipulator of host immune responses in the periodontium. Peptidyl arginine deiminase (PPAD), a recently identified virulence factor of P.

Chemical inhibition of MrkH-dependent activation of type 3 fimbriae synthesis and biofilm formation by Klebsiella pneumoniae [PDF]

npj Biofilms and Microbiomes
Biofilm formation by Klebsiella pneumoniae is mediated by the type 3 fimbriae Mrk, and regulated by MrkH and 3’,5’-cyclic diguanylic acid (c-di-GMP). We sought to identify specific chemical inhibitors of K.

Type1 and 3 fimbriae phenotype and genotype as suitable markers for uropathogenic bacterial pathogenesis via attachment, cell surface hydrophobicity, and biofilm formation in catheter-associated urinary tract infections (CAUTIs) [PDF]

Iranian Journal of Basic Medical Sciences, 2021
Objective(s): Catheters are one of the factors for complicated urinary tract infections. Uropathogenic bacteria can attach to the catheter via cell surface hydrophobicity (CSH), form biofilms, and remain in urinary tract.

Fimbria-mediated bacterial adhesion to human oral epithelium [PDF]

FEMS Microbiology Letters, 2001
Oral mucosa biopsies and saliva samples from 12 individuals were processed for transmission (TEM) and scanning (SEM) electron microscopy with and without ruthenium red staining. Additionally performed microbiological estimations indicated in all bacteriological samples a facultative pathogenic flora. SEM and TEM investigation showed a diverse bacterial

What Flips the Switch? Signals and Stress Regulating Extraintestinal Pathogenic Escherichia coli Type 1 Fimbriae (Pili)

Microorganisms, 2021
Pathogens are exposed to a multitude of harmful conditions imposed by the environment of the host. Bacterial responses against these stresses are pivotal for successful host colonization and pathogenesis. In the case of many E.

Aggregative adherence fimbriae form compact structures as seen by SAXS

Scientific Reports, 2023
Bacterial colonization is mediated by fimbriae, which are thin hair-like appendages dispersed from the bacterial surface. The aggregative adherence fimbriae from enteroaggregative E. coli are secreted through the outer membrane and consist of polymerized
