The Bacteria Isolated From the Urine Cultures of Patients Admitted To Duzce Ataturk State Hospital Urology Outpatient Clinic and Their Antibiotic Resistances

Abstract

Objectives: The aim of this study was to determine the bacteria and their antibiotic resistance ratios isolated from the urine cultures of patients admitted to our hospital's urology outpatient clinics in order to outline the empirical treatment. Methods: Positive cultures of urine samples were evaluated retrospectively. Cultures of >= 10(5) cfu/ml growth were evaluated. Antibiotic resistance tests were performed according to the Clinical and Laboratory Standards Institute (CLSI) suggestions with Kirby-Bauer disc diffusion method using MuellerHinton agar. Results: In this study, E. coli (69%) was the most common isolate; followed by Klebsiella spp. (9%), S. aureus (9%), Enterococcus spp. (7%), Enterobacter spp. (3%), Proteus spp. (2%) and P. aeruginosa (1%). In E. coli strains, resistance to amoxicillin clavulanic acid (AMC), ciprofloxacin (CIP), and trimethoprim sulfamethoxazole (SXT) were 49%, 45%, 44%; respectively. In S. aureus strains, resistance to oxacillin was 58%. Conclusion: As a result, it is put forward that the treatment of urinary tract infections should be arranged according to the urine culture results because of the high resistance ratios of the frequently used empiric antibiotics.
