Assessment of the Antimicrobial Resistance of Urinary Escherichia coli and Some Factors Related to Urinary Tract Infection in Karbala Patients

Background: Urinary tract infection is one of the most common type of infectious disease encountered in the practice of medicine. Antimicrobial resistance is huge problem cause of a great concern throughout the world. This study was curried out to assess the antimicrobial resistance of urinary E. coli and some factors related to urinary tract infection.

Results: Out of the 100 patients studied, the urine samples of 49 patients were found to have culture positive; and out of these, the urine samples of 28 patients were positive for urinary E. coli. Thus the prevalence was 57.1% for E. coli, and 42.9% for other type of bacteria such as Staphylococcus aureus, Hemolytic streptococci, Klebsiella spp., Proteus spp., Enterococcus spp. and Pseudomonas aeruginosa. The results of sensitivity tests showed that the resistance of E. coli was about 10 times higher for nitrofurantoin, ceftazidime and ceftriaxone; relative to amikacin, ampicillin and imipenem.

Aim of the Study: Assessmentof the antimicrobial resistance of urinary E. coli and some factors related to urinary tract infection in Karbala patients.

Conclusions: Escherichia coli remains the most common pathogens isolated form urine samples of patients with urinary tract infection . The resistance of uropathogenic E. coli to antimicrobial drugs has been gradually increasing for commonly used drugs.
