  • Introduction: Urinary tract infections (UTIs) are among the most common human infections. Lack of diagnosis and timely treatment of UTIs can lead to health hazards and dangerous diseases such as preterm delivery, hypertension, urinary tract disorders, and so on. The aim of this study was to identify the bacterial pathogens causing urinary tract infections in outpatients and admitted to Imam Khomeini Hospital and their prevalence in Shirvan city during 2018.
  • Methods: Urine specimens from outpatients and inpatients admitted to Imam Khomeini Hospital's lab, Shirvan, North Khorasan province, Iran, were cultivated in Blood Agar and MacConkey agar (MAC). The culture with and more than 105 CFU/mL bacteria were considered positive. The diagnostic and biochemical tests including morphological examination Gram stain, TSI, SIM, urease, oxidase, 6.5% salt tolerance, citrate, motion, PYR, Bile-esculin and phenylalanine tests; were achieved to identify the isolates.
  • Results: Among 3320 urine samples in 2018, 190 (5.72%) were positive. The prevalence of the isolates were 69.47% for E. coli, 14.21% for Klebsiella species, 3.70% for Staphylococcus epidermidis, 3.15% for Proteus, 2.63% for Staphylococcus saprophyticus, 2.63% for Enterobacter, 1.57% for staphylococcus coagulase negative, 1.05% for Enterococcus sp., 0.53% for Pseudomonas Aeruginosa, 0.53 for Streptococcus, 0.53% for Serattia sp., respectively.
  • Conclusion: According to the results, E.coli is the most common cause of urinary tract infection, which is more than other isolates and is consistent with the results of other studies in different regions. Although the period prevalence of bacterial UTIs was around 5% during 2016-2018 and E.coli and klebsiella the main agents, there are some substitution for other rankings, when we compare them with our previous study.
