Detection of fim, pap, sfa and afa Adhesin-Encoding Operons in Escherichia coli Strains Isolated from Urinary Tract Infections
ABSTRACT Background and objectives: Urinary tract infections (UTIs) are one of the most common infectious diseases caused by bacteria. The primary etiologic agent of UTIs is Escherichia coli. Uropathogenic E.coli (UPEC) strains have a number of specific virulence factors, which can worsen UTIs. This study was performed to...
متن کاملBad bugs and beleaguered bladders: interplay between uropathogenic Escherichia coli and innate host defenses.
Strains of uropathogenic Escherichia coli (UPEC) are the causative agents in the vast majority of all urinary tract infections. Upon entering the urinary tract, UPEC strains face a formidable array of host defenses, including the flow of urine and a panoply of antimicrobial factors. To gain an initial foothold within the bladder, most UPEC strains encode filamentous surface adhesive organelles ...
متن کاملcomplex interplay between type 1 fimbrial expression and flagellum-mediated motility of uropathogenic Escherichia coli.
Type 1 fimbriae and flagella have been previously shown to contribute to the virulence of uropathogenic Escherichia coli (UPEC) within the urinary tract. In this study, the relationship between motility and type 1 fimbrial expression was tested for UPEC strain CFT073 by examining the phenotypic effect of fimbrial expression on motility and the effect that induction of motility has on type 1 fim...
متن کاملRegulatory Interactions among adhesin gene systems of uropathogenic Escherichia coli.
Uropathogenic Escherichia coli strain J96 carries multiple determinants for fimbrial adhesins. The regulatory protein PapB of P fimbriae has previously been implicated in potential coregulatory events. The focB gene of the F1C fimbria determinant is highly homologous to papB; the translated sequences share 81% identity. In this study we investigated the role of PapB and FocB in regulation of th...
متن کاملDetection of pap, sfa, afa and fim Adhesin-Encoding Operons in Avian Pathogenic Escherichia coli
The occurrence of fim, pap, sfa, and afa genes was evaluated in 200 Escherichia coli strains isolated from chickens diagnosed with omphalitis, salpingitis, swollen head syndrome, or chronic respiratory disease. Analysis of the strains by colony hybridization tests demonstrated that 96% of the isolates were fim, 16% were pap, and 6% were sfa. None of the isolates was afa. The fim gene occurred i...
