Abstract
Background and objectives: Extended-Spectrum Beta-Lactamase (ESBL) producing
Escherichia coli is the most prevalent cause of Urinary Tract Infections (UTIs). The present
research was done to study the prevalence and antibiotic resistance properties of ESBL and non-
ESBL producing Escherichia coli strains isolated from the cases of UTIs. Materials and
methods: Five-hundred and one urine samples were collected and cultured for E. coli. Positive
samples were analyzed for presence of ESBL. Antibiotic resistance pattern of strains was
analyzed using disk diffusion method. Results: Three-hundred and twenty-seven out of 501
(65.26%) urine specimens were positive for E. coli. Older than 40 years male (65.21%) and also
younger than 20 years female (96.77%) had the highest prevalence of E. coli. Prevalence of
ESBL and non-ESBL producing strains were 15.29% and 84.70%, respectively. ESBL E. coli
harbored the highest prevalence of resistance against ampicillin (100%), ceftriaxone (100%),
cefalexin (98%) and piperacillin (96%). Non-ESBL E. coli strains harbored the highest
prevalence of resistance against ciprofloxacin (76.89%), ampicillin (72.92%) and gentamicin
(68.95%). Conclusion: Imipenem, nitrofurantoin and tobramycin had good activity against both
ESBL and non-ESBL producing E. coli strains. Further researches are required to found other
epidemiological aspects of ESBL and non-ESBL producing E. coli strains isolated from UTIs.

Key words: Extended-Spectrum Beta-Lactamase, Escherichia coli, Antibiotic resistance, Urinary Tract Infections.
