P fimbriae

Bacterial counts were higher when P-fimbrial expression was detected than when the pap+/prs+ strain showed a negative phenotype. The results suggested that P fimbriae enhance the establishment of bacteriuria and fulfil the molecular Koch postulates as a colonization factor in the human urinary tract. Fimbriae are helix-like structures with a remarkable adaptability, offering safeguarding for bacteria exposed to changing fluid forces in the urinary tract. We challenged this property of P-fimbriae by cross-linking their subunits with shaft-specific antibodies and measuring the corresponding force response at a single organelle level. 1993-04-01 3.2 P fimbriae. P fimbriae are classically associated with pyelonephritis.

P-fimbriae, bacterial adhesion, and pyelonephritis. Winberg J. PMCID: PMC1628452 PMID: 6142698 [PubMed - indexed for MEDLINE] S fimbriae and type 1 fimbriae were equally common in resident and transient strains. The results indicate that not only P fimbriae, but also, certain capsules and the ability to produce the siderophore aerobactin might contribute to persistence of E. coli in the large intestine. 1993-04-01 · Binding of P Fimbriae to Glycolipid Receptors A primary function of the P fimbriae is to bind to human uroepithelial cells and to enable E. coli to colonize the human urinary tract.

For other helix-like organelles similar to P-fimbriae, e.g., the type 1 fimbriae and the CFA/I fimbriae, it has been shown that the elasticity of the shaft is important for sustained adhesion 2,5,7. fimbriae, Dr haemagglutinin and three varieties of the P fimbrial papG adhesin) and other virulence traits (KI and K5 capsule, haemolysin and aerobactin) using multiplex PCR. Forty-four percent of the resident clones carried genes for P fimbriae, K1 or K5 capsule, and aerobactin, compared with only 3% of transient clones (P < 0-0001). Fimbriae are helix-like structures with a remarkable adaptability, offering safeguarding for bacteria exposed to changing fluid forces in the urinary tract.
