| Introduction: Increasing resistance to anti-microbial agents in bacteria is a major problem around the world. So, our kno-wledge about the bacterial strains status causing urinary tract infection and their resistance against common antibiotics is an important issue in treatment. The aim of this study was to indentify the bacteria causing urinary tract infections and to determine their antibiotic resistance in ad-ults hospitalized and referred to the Farshc-hian hospital in Hamadan in 2011.
Materials & Methods: This descriptive cross-sectional study was performed on 214 individuals hospitalized in or referred to the Farshchian hospital in 2011. Morphological evaluation and identification of the isolated bacteria were performed by Gram staining and biochemical tests. Antibiotic suscept-ibility tests were done with cotrimoxazole, nalidixic acid, gentamicin, ceftriaxone, nitr-ofurantoin, tobramycin, amoxicillin, oflo-xacin and ciprofloxacin disks and the Kirby-Bauer method.
Findings: Of 141 patients, 54.2% and 45.7% were female and male, respectively. The most common causes of infection were Escherichia coli (%61), Enterobacter spp. (%10.7), staphylococcus saprophyticus (%8.5), Pesudomonas aeruginosa (%7.9) and Proteus spp.(%7.1). In total, regardless of the type of bacteria, the highest resis-tance was against amoxicillin and the low-est resistance was against nalidixic acid. Escherichia coli as the most common cause of urinary tract infection and had the same pattern of infection in both sexes.
Discussion & Conclusion: According to our study, E. coli was the most common cause of urinary tract infection and the strain had the highest and lowest resistances against amoxicillin and nalidixic acid, respectively. |
