Abstract

|
|
Urinary tract infection(UTI) is one of the most common infectious diseases. Recently, The increasing frequency of clinical failure of UTI treatment may be due to emerging resistance of commonly prescribed antibiotics. We studied the causative microorganisms and their antibiotic sensitivities in UTI for the first choice of antibiotics. We analyzed 2,314 microorganisms and their antibiotic sensitivities for recent 4 years. The most prevalent causative organism was E. coli(42.8%), followed by Enterococcus(7.7%), CNS(7.5%), and Pseudomonas spp(5.5%) etc. The mean rates of sensitivities were 72.7, 76.2, 79.8, 61.7, 97.6, and 99.8% to cefmetazole(CMT), cefotaxime(CTX), amikacin(AMK), ciprofloxacin(CPR), imipenem(IMP), and vancomycin(VAN) respectively. And especially trimethoprim/sulfamethxazole(TMP) displayed sensitivity of 57.1%. We consider that E. coli is the main cause of UTI. But, we should concern about the increase of other organisms. TMP showed poor sensitivity to most causative microorganisms of UTI but CMT and CPR showed relatively good sensitivities to most causative organism. Though first drug of choice was CMT and CPR, it is necessary to identify further changes among causative microorganisms of UTI and antibiotics sensitivity.
