Abstract:Introduction: Urinary tract infections (UTI’s) are one of the most common bacterial infections in community and hospital settings and it is important to know the etiology and susceptibility pattern of uropathogens for optimum management of UTI’s.Aim & Objectives:This study was conducted to know the etiologyof UTI and to determine the antibiotic resistance pattern of these isolates.Materials & Methods: A prospective cross sectional study was done on 537 and 486 consecutive urine samples from January to May 2015 and 2016. Isolates obtained were identified by conventional biochemical methods and antimicrobial susceptibility testing was done by Kirby Bauer disk diffusion method as per CLSI guidelines.Results: The prevalence of UTI was 41.71% and 51.85% in 2015 and 2016 respectively. 129 (57.59%) and 148 (58.73%) females and 95(42.41%) and 104(41.27%) males were infected in 2015 and 2016 respectively.Escherichia coli (55.25%) was the predominant organism isolated. An increased resistance to norfloxacin ,ampicillin and cefotaxime were shown in 2016 compared to the antimicrobial resistance pattern obtained in 2015. All the gram negative bacilli studied were sensitive to Imipenem and Piperacillin- Tazobactam. Conclusion:Constant surveillance of resistance rate of uropathogens is necessary to formulate local antibiotic policy and to assist clinicians in the rational choice of antibiotic therapy.
