Fimbrial adhesion is a Virulence Determinant which is classified under Adhesins category of virulence factor of uropathogenic Escherichia coli. Afimbrial adhesin Protein with swissprot accession number P12730, of length 181 amino was selected for modeling using Bioinformatics tools. Modelled protein has been submitted to protein model database and has been assigned an accession number of PM0075...

The mass profiles of cell-free extracts of 180 commensal and pathogenic strains of Escherichia coli were determined by MALDI-TOF mass spectrometry (MS). While some peaks were highly conserved in all E. coli, several peaks occurred only in some strains, showing heterogeneity among them. We did not detect strain-specific peaks for any of the E. coli categories tested. However, review of the fully...

We previously demonstrated that some Escherichia coli strains with uropathogenic properties survived treatment stages of sewage treatment plants (STPs), suggesting that they may be released into the environment. We investigated the presence of such strains in the surrounding environmental waters of four STPs from which these persistent strains were isolated. In all, 264 E. coli isolates were co...

In the remote Japanese community of Saku, a rural town in the Nagano Prefecture, a large proportion of outpatient urinary tract infections was caused by well-recognized globally dispersed clonal lineages of uropathogenic Escherichia coli (UPEC). However, most of these strains were drug susceptible, suggesting that factors other than selection pressure account for the clonal spread of drug-susce...

BACKGROUND & AIMS Infrared spectroscopy is an increasingly common method for bacterial strains' testing. For the analysis of bacterial IR spectra, advanced mathematical methods such as artificial neural networks must be used. The combination of these two methods has been used previously to analyze taxonomic affiliation of bacteria. The aim of this study was the classification of Escherichia col...

background and objectives: urinary tract infection (uti) is one of the most common infections in the world. the majority of utis are caused by uropathogenic escherichia coli (upec) strains. fimh and flic are the most important virulence factors of upec. to date, any ideal vaccine against uti has not been approved for human use and we need to test new targets to develop an ideal vaccine against ...

BACKGROUND Ureters are fundamental for keeping kidneys free from uropathogenic Escherichia coli (UPEC), but we have shown that 2 strains (J96 and 536) can subvert this role and reduce ureteric contractility. To determine whether this is (1) a widespread feature of UPEC, (2) exhibited only by UPEC, and (3) dependent upon type 1 fimbriae, we analyzed strains representing epidemiologically importa...

Sixty strains of Escherichia coli, isolated by hemoculture, from septicemic Brazilian patients were evaluated to determine their serogroup and invasivity to Vero cells. All 60 patients died within 2 days of hospitalization. Furthermore, the molecular study of the following extraintestinal pathogenic E. coli-associated virulence factor (VF) genes was performed by PCR: i) adhesins: type 1 fimbria...

Investigation into the pathogenesis of Escherichia coli urinary tract infection has provided numerous insights into the mechanisms by which bacteria adhere, grow and persist in association with host tissue. Many molecular details concerning the interaction of these bacteria with their host have been elucidated, and the murine model of cystitis has generated a new paradigm by which acute and rec...
