Abstract:
OBJECTIVE To study the three-stage reports method using in clinical diagnosis of urinary system infections,and its value in order to fasten the clinical diagnosis and treatment.METHODS A total of 3349 urines specimens used a sequential three-stage reports method to prospectively evaluate and determine the validity of direct antimicrobial agent susceptibility testing by traditional method and VITEK-32.The first report was by Gram stained,the second report by criteria for initiating direct susceptibility testing,and third report was by standardized disk diffusion method and VITEK-32.RESULTS From 3349 samples the Gram negativstained smears were 746(22.3%),Gram negative bacilli were 1365(40.7%) the Gram positive cocci were 1036(31.0%) and the fungi were 202(6.0%).Escherichia coli rated the top one(55.7%),followed with Staphylococcus saprophyticus subsp saprophyticus 437(42.2%),Enterococcus faecalis 389(37.5%),Proteus,Klebsiella pneumoniae,Pseudomones aeroginose,and fungi.Enterobacteriaceae were showed increasing drug resistance trend,but still sensitive to imipenem(100.0%).G+-cocci were also showed serious drug resistance trend,but still sensitive to vancomycin(100.0%)(except E.faesium).CONCLUSIONS Three-stage method using in clinical diepnosis of urinary system infections is very important.Enterobacteriaceae are the main infectious bacteria in urinary system infection.Rational use of antibiotics should be carried out according to urine culture result.
