Occurrence of Adhesin-encoding Operons in Escherichia Coli Isolated from Breeders with Salpingitis and Chicks with Omphalitis
The occurrence of fim, pap and sfa operons in Escherichia coli isolated from breeders with salpingitis and chicks with omphalitis was evaluated. Analysis of 100 E. coli isolates, by colony hybridization tests, showed that 78 (78%) were fim, one (1%) was sfa, seven (7%) were fim associated with pap, eigth (8%) were fim and sfa, one (1%) was fimpapsfa and five (5%) isolates did not hybridize with...
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 کاملDetermination of Adhesin Encoding Genes in Escherichia coli Isolates from Omphalitis of Chicks
Problem statement: Omphalitis is one of the most common causes of mortality in chicks during the first week after hatching. Escherichia coli strains are the most common isolated bacteria from omphalitis cases of chickens. Bacterial colonization in the host cells surfaces is a critical first step in the pathogenesis of avian pathogenic Escherichia coli isolates. Thus the current study was undert...
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 کاملdetection of pap, sfa, afa, foc, and fim adhesin-encoding operons in uropathogenic escherichia coli isolates collected from patients with urinary tract infection
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...
