Current efficacy of antibiotics against Klebsiella isolates from urine samples - a multi-centric experience in Karachi.

Due to emergence of bacterial resistant strains, the effectiveness of current antibiotic treatment without culture/sensitivity testing is questionable. Our study aims to assess the present sensitivity profiles of Klebsiella isolates from urine samples and provide options for empiric prescription in critically ill patients. Klebsiella pneumoniae isolates collected over a period of 28 months till January 2011 from 1,617 urine samples of subjects presenting with Urinary Tract Infections were identified at a local diagnostic lab using standard protocol and subjected to Kirby-Bauer disk diffusion sensitivity testing.
