objective to identify the spectrum of pathogenic microorganisms of urinary tract infection and the drug resistance in a hospital setting. methods the pathogenic microorganisms isolated from 3117 mid-stream urine samples of patients admitted in hangzhou first people's hospital from 2005 to 2007 and their drug resistance results were retrospectively analyzed. results bacteria were the most prevalent microorganisms in the urinary tract infection, and followed by fungus, mycoplasma and chlamydia. escherichia eoli accounted for the largest proportion of gram-negative bacteria, in which the esbls positive strains accounted for 51.2%, and their drug resistance rate was much higher than that of esbls negative strains. main gram-positive coccobacteria was all sensitive to vancomycin, and relatively sensitive to nitrofurantnin and ampicillin. conclusions escherichia coli continue to prevail upon the spectrum of pathogenic microorganism of the urinary tract infection, and the fungus, mycoplasma and chlamydia infections are rising. antibacterial agents should be used under the guidance of drug sensitivity test, and the combined use should be avoidd.展开更多
