Determination of virulence and quinolone resistance genes and biofilm production among uropathogenic Escherichia coli strains isolated from clinical specimens in Iran

Abstract: Background: Uropathogenic Escherichia coli (UPEC) is the main cause of nosocomial urinary tract infections. The high rates of antimicrobial resistance among UPEC have markedly reduced the remedial options and raised the therapeutic costs and fatality rates. This study analyzed the ability of extended spectrum beta-lactamase (ESBL) production and the presence of plasmid-mediated quinolone resistance genes among UPEC isolates. It also assessed the correlation between plasmid-mediated quinolone resistance genes, … Show more

“…The high prevalence of the type 1 fimbria gene was in line with a previous study indicating a high incidence of type 1 fimbriae among uropathogenic E. coli (35), especially in CAUTIs. The difference in the prevalence of virulence genes among different studies can be attributed to the difference in virulence gene distribution among different strains of E. coli.…”

“…There is also a known ability of E. colito exchange its genetic material and transfer genetic virulence factors, besides the effects of various antibiotics intake that leads to the elimination of certain strains with different virulence genes. Moreover, the presence of some virulence genes such as pap-c may be associated with certain types of UTIs, such as pyelonephritis, more than with its presence in cystitis (35). There was a significant association between the presence of fim-H, pap, afa-1, and hyl genes (P = 0.001, P = 0.001, P = 0.04, P = 0.046 respectively) and the capacity to form biofilm in isolated E. coli.…”

“…UTIs have become a global health problem due to the difficulty of detecting antibiotic-resistant pathogens (Ndzime et al 2021 ). Almost half of the women and 12% of men have this infection once in their lifetime (Tabatabaie et al 2022 ). Due to the hormonal and anatomical changes that occur during pregnancy, women are more likely to get UTIs (Kalinderi et al 2018 ).…”
