the association of virulence determinants of uropathogenic escherichia coli with antibiotic resistance
conclusions the results showed that e. coli isolated from patients with uti had eight virulence factors with high frequencies. moreover, these results alleged a direct connection between virulence factors and antimicrobial resistance in e. coli. results the frequency of virulence factors papc, afa, sfa/foc, fimh, hly, neuc, ibea, and iucc were 53.3%, 51.7%, 53.3%, 56.7%, 23.3%, 31.7%, 20%, and ...
متن کاملImpact of the RNA chaperone Hfq on the fitness and virulence potential of uropathogenic Escherichia coli.
Hfq is a bacterial RNA chaperone involved in the posttranscriptional regulation of many stress-inducible genes via small noncoding RNAs. Here, we show that Hfq is critical for the uropathogenic Escherichia coli (UPEC) isolate UTI89 to effectively colonize the bladder and kidneys in a murine urinary tract infection model system. The disruption of hfq did not affect bacterial adherence to or inva...
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 کاملThe Association of Virulence Determinants of Uropathogenic Escherichia coli With Antibiotic Resistance
BACKGROUND The emergence of antimicrobial resistant strains of Escherichia coli has raised considerable interest in understanding the diversity and epidemiology of E. coli infections in humans. Virulence factors of E. coli determine the specific infections caused by this microorganism. OBJECTIVES This study aimed to determine the prevalence of eight E. coli virulence factors and their associa...
متن کاملgenotyping of virulence factors of uropathogenic escherichia coli by pcr
background: escherichia coli is the most causative agent of urinary tract infections (utis). apart from all human infectious diseases, uti have a high prevalence and in most cases, escherichia coli is a dominance bacterium which can cause pyelonephritis and cystitis. the aim of the study was to determine the occurrence of some virulence genes expressing fimbriae, production of hemolysin and aer...
