ABSTRACT
Bacteria are the commonest etiological factor among the microbes that cause UTIs. The most prevalent bacteria identified in the lab are Escherichia coli, Klebsiella pneumonia and Pseudomonas aeruginosa. Antibiotics are the empiric therapy for such infections but the reoccurrence rate is becoming high owing to the development of resistance due to their irrational and indiscriminate use across the globe. This study was designed on UTI cases of OPD, Medical, Nephrology, Surgical, Main OT, Urology and ICU wards of Allied hospital Faisalabad. 11 antibiotics were used which showed that E. coli is sensitive to Amikacin, Gentamicin, Imipenem, Piperacillin tazobactam, and Polymyxin B. Klebsiella pneumonia showed sensitivity for Amikacin, Gentamicin, Nitrofurantoin, Imipenem, Polymyxin B, Piperacillin tazobactam and Trimethoprim-sulfamethoxazole. While Pseudomonas aurignosa showed resistance to Amikacin, Ciprofloxacin, Gentamicin, Piperacillin tazobactam, Imipenem, and Polymyxin B. E. coli exhibited the highest sensitivity for Piperacillin tazobactam, Klebsiella pneumonia for Imipenem and Pseudomonas aurignosa for Ciprofloxacin. Further, the isolated DNA samples of these microorganisms were confirmed by gel electrophoresis and subjected to molecular characterization by performing trace file and phylogenetic tree analysis.
