Abstract

The study was carried out to detect the adhesive genes pap (pyelonephritis associated pili), sfa (S fimbrial adhesin) and afa (afimbrial adhesin) from Escherichia coli strains isolated in patients diagnosed with urinary tract infection (UTI). A total of 23% of the isolates were positive for pap, sfa and afa genes with a prevalence of 60.87% (14/23), 39.1% (9/23) and 39.1% (9/23), respectively. Prevalence of multiple adhesive genes was 8.7% (2/23) for pap and afa, 30.43% (7/23) for pap and sfa. Significant numbers of isolates were positive for Congo red binding (80%) and haemolysin production 60%. The prevalence of multiple adhesive genes indicate the potential to adhere and subsequently cause a systemic infection among UTI patients.
