Abstract

Introduction: Etiological factors of community-acquired urinary tract infections (UTI) are specific for age, gender, season, complication of UTI and type of UTI. Their prevalence and susceptibility to antimicrobial agents shows geographic and time variability. Purpose: To evaluate etiological characteristics of acute communityacquired UTI in hospitalised patients. Patients and methods: This retrospective-prospective study included 200 adult patients with community-acquired UTI who were, in view of the serious clinical picture and unsuccessful ambulatory treatment, hospitalised in the Clinic for Infectious Diseases in Tuzla, for a period of two years (2006 and 2007). The data concerning the age, gender, season, complication of UTI and type of UTI were collected from the patient’s records. Urine analysis was done following standard microbiological methods, and the antibiogram was done following standard disc-diffusion method on the Müeller-Hinton agar. Work results: The dominant etiological factors of UTI were: E. coli (73.5%), Klebsiella spp. (8.5%), Proteus mirabilis (5.5%), Pseudomonas aeruginosa (4.5%) and Enterococcus faecalis (3%). The predominant etiological factor of this UTI was E. coli (P
