Detection of pap, sfa, afa, foc, and fim Adhesin-Encoding Operons in Uropathogenic Escherichia coli Isolates Collected From Patients With Urinary Tract Infection
BACKGROUND Uropathogenic Escherichia coli (UPEC) with its virulence factors is the most prevalent cause of urinary tract infection (UTI). OBJECTIVES This study aimed to determine the occurrence of fim, pap, sfa, and afa genes among 100 UPEC isolates collected from patients diagnosed with UTI. MATERIALS AND METHODS A total of 100 UPEC isolates were obtained from urine samples of patients wit...

conclusions these results indicate that the pcr method is a powerful genotypic assay for the detection of adhesin-encoding operons. thus, this assay can be recommended for clinical use to detect virulent urinary e. coli strains, as well as epidemiological studies. materials and methods a total of 100 upec isolates were obtained from urine samples of patients with uti. the prevalence of 5 virule...
متن کاملDetection 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 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...
متن کاملcomparison of the common adhesin coding operons distribution in uropathogenic and phylogenetic group b2 and a escherichia coli isolates
background escherichia coli is one of the most causative pathogen of urinary tract infection. urinary tract infections (utis) are the second most common cause of morbidity and remain a serious health concern among the clinicians. the severity of uti caused by uropathogenic e. coli (upec) is due to the expression of a wide spectrum of virulent factors such as adhesin coding operons. little is kn...
