Abstract:
OBJECTIVE To determine the bacterial distribution and resistance status in urinary system infections among old patients with primary susceptibility testing on urine samples. METHODS A total of 990 urine specimens were examined over 3 years to determine the validity of direct antimicrobial agent susceptibility testing.A total of 1149 strains collected from inpatient urine specimens during Oct 2002-Oct 2005 were identified and the drug resistance test was performed. RESULTS Escherichia coli rated the top one(57.9%),followed with Enterococcus,Proteus,Klebsiella pneumoniae,Pseudomonas aeruginosa,Staphylococcus and fungi.Enterobacteriaceae were showed increasing drug resistance trend,but still sensitive to imipenem(100%).G~+-cocci were also showed serious drug resistance trend,but still sensitive to vancomycin(100%)(except Enterococcus faecium). CONCLUSIONS Enterobacteriaceae are the main infectious bacteria in urinary system infection.Rational use of antibiotics should be carried out according to urine culture result.
