Analysis of Antibiotic Resistance in Bacterial Strains Isolated from Urine Cultures of Patients Referred to Clinical Laboratories of Ilam City during 2012

One the most prevalence infection is Urinary tracts infection(UTI). Failure in diagnose and treatment of UTI causes severe renal complications such as renal parenchyma damage, hypertension and chronic renal failure .wasteful use of antibiotics were caused resistance to common drugs available.This study aims to investigate the pattern antibiotic resistance in bacterial strains isolated from urine of patients referred to clinical laboratory of Ilam during 2012.
In a retrospective study, data from portfolio patients referred to university hospitals and private laboratories in the city of Ilam were collected by census sampling . Spss software t-test and x2 were used for analysing.
Findings: Escherichia coli (28.9%), Staphylococcus aureus (28.8%), Staphylococcus saprophyticus (13%), Staphylococcus epidermidis (9%), Streptococcus. Spp(8%) and Enterococcus (7%) were the most common pathogen. coterimoxazole and amikacin had the highest and lowest rates of antibiotic resistance.
Discussion & Result of this study indicated that E. coli is the most common pathogen in patient referred to laboratory and hospital of Ilam city. The highest resistant was observed for coterimoxazole . It is recommended that use of it should be limited.
