摘要

Urinary Tract Infections (UTI), and their complications, cause serious health problems, which affect millions of people every year. Infections of the urinary tract are the second most common type of infection in the body and approximately 20% of women are especially prone to UTIs for reasons not yet well understood. Urinary Tract Infections in men are not as common as in women yet can be very serious when they do occur. Accurate identification of bacterial isolates is an essential task of the clinical microbiology laboratory. Objectives: The purpose of this study was to determine the incidence and variety of the causative microbial agents of UTIs in patients who had referred to a medical laboratory of Kashani and Hajar hospital in Shahrekord, Iran. Patients and Methods: In this cross-sectional study 147 urine samples of patients (urine test results were positive for UTIs) were examined during April to September 2013. A total of 147 urine samples of patients with clinical symptoms of UTI who had been referred to a medical laboratory of Kashani and Hajar hospital in Shahrekord (Iran), were collected and processed immediately for laboratory analysis. Results: Escherichia coli was identified as the most common causative agent of UTIs (51.70% of total isolates in both sexes), followed by Klebsiella pneumoniae (K. Pneumoniae) (16.32%). Frequency of Proteus spp., Acinetobacter spp., Entrobacter spp., Citrobacter spp., Pseudomonas aeruginosa (P. aeruginosa) and Providencia spp. was 10.88%, 6.12%, 5.44%, 4.08%, 3.40% and 2.04%, respectively. Statistical analysis by Fisher exact test showed that there was no significant relationship between the type of bacteria and gender (P > 0.05). Chi square test showed that there was no significant relationship between the type of bacteria and the use of catheter and age group (P > 0.05). However, there was a significant relationship between the type of bacteria and the history of hospitalization (P > 0.05). Conclusions: Our findings implied that a wide range of bacteria could be involved in creating urinary tract infection in patients referred to a medical laboratory of Kashani and Hajar hospital in Shahrekord, Iran. Regardless of age, sex and the use of catheter, a wide range of bacteria could be involved in urinary tract infections.

Pneumoniae）（16.32％）。变形杆菌属，不动杆菌属，肠杆菌属，柠檬酸杆菌属，铜绿假单胞菌（铜绿假单胞菌）和普罗维登斯属的频率。分别为10.88％，6.12％，5.44％，4.08％，3.40％和2.04％。 Fisher精确检验的统计分析表明，细菌的类型与性别之间没有显着相关性（P> 0.05）。卡方检验表明，细菌的种类与导管的使用和年龄组之间无显着相关性（P> 0.05）。但是，细菌类型与住院病史之间存在显着相关性（P> 0.05）。结论：我们的研究结果表明，转诊至伊朗Shahrekord的Kashani和Hajar医院医学实验室的患者，广泛的细菌可能与尿路感染有关。无论年龄，性别和使用导管如何，泌尿道感染均可能涉及多种细菌。
