Abstract:
OBJECTIVE To investigate the distribution and drug resistance of common bacteria isolated from our hospital in 2001-2005,and to guide the appropriate use of antibiotics.METHODS The resistant patterns were analyzed by retrospective analysis from 2001 to 2005.RESULTS There were 268 Gram-positive strains(27.21%) and 717 Gram-negative strains(72.79%).The most prevalent isolated strains were Escherichia coli,Pseudomonas aeruginosa,Staphylococcus aureus,Stenotrophomonas maltophilia,Klebsiella pneumoniae and Staphylococcus epidermidis,which were increasing year by year.Imipenem was the most sensitive for Gram-negative rods,and vancomycin was the most sensitive for Gram-positive cocci.The resistance rate of E.coli to imipenem and ceftazidime was below 30%.All S.aureus strains were susceptiple to vancomycin.CONCLUSIONS The rapid emergency of nosocomial multidrug resistant strains presents significant therapeutic challenges and therefore,the rational use of antibiotic therapy based on susceptibility tests should be emphasized.Understanding the distribution of isolates and drug susceptibility test results of different bacteria could help doctors to decide the rational antimicrobial therapy.
