Antibacterial susceptibility of commonly encountered uropathogens in al-Hussain teaching hospital-Dhi-Qar province : a retrospective study

الملخص EN

Background : Antibacterial resistance is an evolving problem which reflects the antibacterial prescription in our community.

Such problem has great impact on proper management and consequences of urinary tract infection (UTI) Aim : To determine the relative role of uropathogens and their antibiotic susceptibility pattern in community-acquired urinary tract infection (UTI) in Al-Hussain Teaching Hospital / Thi-Qar Province.

Methodology : A retrospective study was carried out to review urine culture and antibiotic sensitivity testing from symptomatic outpatients visiting Al-Hussain Teaching Hospitals / Thi-Qar Province over the period from June 2007 to June 2008.

Results : Of 236 samples, 124 (52.5 %) were culture positive.

Staphylococci and Escherichia coli were the leading cause of UTI accounting for 75 % of all isolates.

The rates and roles of other pathogens, including Klebsiella species (11%), Pseudomonas species (8 %), Enterobacter, Proteus, and Streptococci were responsible for the remaining 6 %.

More than 75 % of isolated Staphylococci and Escherichia coli were sensitive to nitrofurantoin and amikacin, while more than 60 % were sensitive to ciprofloxacin.

Sensitivity to commonly prescribed antibacterials as co-trimoxazole, amoxicillin, ampicillin and gentamicin were less.

Conclusion : Common uropathogens were highly sensitive to nitrofurantoin, amikacin and to lesser extent to ciprofloxacin, while exhibiting low sensitivity pattern against commonly prescribed antibiotics including co-trimoxazole, amoxicillin, ampicillin, nalidixic acid and gentamicin.
