RESUMEN
Background: Urinary tract infections [UTIs] constitute important bacterial disease which contributes to significant morbidity world-wide. Empirical treatment in patients suffering from UTI depends upon the local knowledge of common microorganisms responsible for UTI in that geographical area as well as their antimicrobial susceptibility patterns
Objectives: To determine the frequency and antimicrobial susceptibility of uropathogens which are responsible for urinary tract infections. Study Design: Experimental study. Setting: Department of Pathology, Frontier Medical and Dental College and Mohi Ud Din Islamic Medical College. Period: January 2015 to June 2015
Material and methods: Total of 113 patients were included in the study. Urine samples were cultured on MacConkey's agar and Cysteine Lactose Electrolyte Deficient [CLED] agar. Micro-organisms were identified using standard tests and antimicrobial susceptibility was checked using modified Kirby Bauer method following Clinical and Laboratory Standards Institute [CLSI] guidelines
Results: The average age of patients was 32.19 +/- 16.47 years. Gram negative organisms accounted for majority of cases, about 89 [78.76%] cases. Escherichia coli was the most common micro-organism which was found in 50 [44.24%] cases followed by Staphylococcus aureus in 24 [21.24%], Enterobacter spp. in 19 [16.81%], Klebsiella spp. in 11 [9.73%] and Proteus spp. in 9 [7.96%] cases. E. coli was sensitive to imipenem and ciprofloxacin and was resistant to amoxicillin/clavulanic acid and gentamicin
Conclusion: Gram negative organisms are largely responsible for UTIs and E. coli being the most common etiological agent. E. coli is sensitive to commonly prescribed drugs for UTI like ciprofloxacin
