Abstract
Background:In wide range, urinary tract infection (UTI) is a substantial and second most popular bacterial infection affecting individuals of overall ages worldwide. The chronicity of divergent bacterial isolates and their propensity to various antibiotics may contradict widely, peculiarly in hospitalized patients, this makes the survey of vulnerability pattern extremely mandatory for correct selection of antibiotics. Objective: To appraise antimicrobial susceptibility pattern of the Gram negative organisms identified from urine cultures of hospitalized patients. Methodology:Total 500 urine samples from hospitalized patients with significant bacteriuria were surveyed. Using Blood and MacConckey agar, samples were inoculated. Further identification and investigation of organisms was done by standard Microbiological methods. Antimicrobial Susceptibility pattern was interpreted by Modified Kirby- Bauer's disc diffusion method with the group of 15 drugs as per Clinical Laboratories Standard Institute (CLSI) protocols.Results:UTIs were frequent in females 290 (58%). Familiar organism found was Escherichia coli 260 (52%) further accompanied by Klebsiellaspp.120 (24%), Pseudomonas spp.40 (8%), Proteus spp. 38 (7.6%), Citrobacter spp.25(5%) and Acinetobacterspp. 17 (3.4%). Mass of the strains were found sensitive to nitrofurantoin followed by amikacin, piperacillin-tazobactamand cotrimoxazole. Commonly prescribed fluroquinolones were found least effective for treatment of UTI. All the strains were found sensitive to imipenem. Extended spectrum beta lactamase (ESBL) was noted in E.coli and in Klebsiella spp.Conclusion:To break the continuity of non selective use of antibiotics and to intercept further development of bacterial drug resistance, proper knowledge of susceptibility pattern of uropathogens in particular area is very important before prescribing any empirical antibiotic therapy
