Expression of P fimbriae of uropathogenic Escherichia coli strains.
The occurrence of P fimbriae in a total of 222 uropathogenic Escherichia coli (UPEC) strains was investigated. Out of the total, 31 (14%) were P fimbriated. Of 24 pyelonephritogenic E. coli strains, three (13%) with P fimbriae occurred in children with clinical pyelonephritis, and of 198 E. coli strains 29 (15%) occurred in children with cystitis. Prevalence of P fimbriae of E. coli strains was...
متن کاملA-Type proanthocyanidin trimers from cranberry that inhibit adherence of uropathogenic P-fimbriated Escherichia coli.
Three proanthocyanidin trimers possessing A-type interflavanoid linkages, epicatechin-(4beta-->6)-epicatechin-(4beta-->8, 2beta-->O-->7)-epicatechin (4), epicatechin-(4beta-->8, 2beta-->O-->7)-epicatechin-(4beta-->8)-epicatechin (5), and epicatechin-(4beta-->8)-epicatechin-(4beta-->8, 2beta-->O-->7)-epicatechin (6), were isolated from the ripe fruits of Vaccinium macrocarpon (cranberry) and pre...
متن کاملNovel mechanism of P-fimbriated Escherichia coli virulence in pyelonephritis.
U rinary tract infections (UTI) are among the most frequently encountered community-acquired or nosocomial infections. The disease burden of UTI is estimated to be 150 million cases annually worldwide (1). Catheterassociated UTI is the most frequent source of Gram-negative sepsis in hospitalized patients (2). The spectrum of disease in UTI includes cystitis, pyelonephritis, urosepsis, catheter-...
متن کاملVirulence characteristics and antimicrobial susceptibility of uropathogenic Escherichia coli strains.
Eight virulence factors associated with uropathogenic Escherichia coli (UPEC) were investigated in 204 clinical isolates of E. coli recovered from urine cultures at counts ≥10(5). The bacteria were classified into two groups according to the number of leukocytes in urine samples from which they were isolated: group I ≤8 leukocytes/hpf, 104 strains; group II >8 leukocytes/hpf, 100 strains....
متن کاملBiological and genetic characteristics of uropathogenic Escherichia coli strains.
The aim of the present study was to determine biological characteristics such as expression of fimbriae, Congo red binding, production of hemolysin and aerobactin, adhesion to HeLa and uroepithelial cells and invasion of HeLa cells by Escherichia coli isolates obtained from patients showing clinical signs of urinary tract infection (UTI). Also, the presence of genes (apa, afa, spa) for fimbria ...
