In the last years the antibiotic resistance is increasing, and self-medication is no longer the only reason. The study was designed to compare community urinary tract infections (UTI) and hospitalized patients’ UTI.


We performed a retrospective study of the resistance pattern of the main strains isolated from the hospitalized patients admitted to the Emergency Military Hospital in Cluj-Napoca between 01 January – 30 June 2013, and from the urine sample of the ambulatory patients, during the same period. For antibiotic susceptibility we used the semiautomatic VITEK 2 system and the diffusimetric method. We studied demographic characteristics, in correlation with microbiological data.


For the hospitalized patients: from 317 samples, 209 were positive, in which we isolated E coli=79%, Enterobacter=9.5%, Proteus spp=5%, Klebsiella=5%, Enterococcus spp, Serratia spp, Staphylococcus=1.5%. The E coli sensitivity to antimicrobial drugs was found to be as follows: ampicillin=30%, cefepime=50%, norfloxacin=62%, ofloxacin, ciprofloxacin=68%, biseptol=63%, amoxicillin+clavulanic acid=70%, ceftazidime=85%, amikacin=98%, nitrofurantoin and carbapenem=100%.

For the ambulatory patients: from 605 urinary samples, 318 were positive, in which we isolated: E coli=72.5%, Enterobacter=12.5%, Proteus=10%-mainly nosocomial, after prostatectomy or urinary catheter, Klebsiella, Enterococcus, Citrobacter=5%.


Urine culture is a routine microbiological investigation, even when not indicated. The treatment of asymptomatic bacteriuria is a controversial issue, especially for ambulatory patients. E coli remains the most common strain isolated in urine cultures, and the antimicrobial stewardship is necessary.
