RESUMEN
OBJECTIVE To acquaint pathogen distribution of infection and present drug-resistance conditions of the commonly encountered pathogens.METHODS The statistics of the antimicrobial susceptibility testing of all the clinical isolates from Jan to Nov 2006 in our hospital was condncted.RESULTS Totally 1850 bacteria strains were isolated.From them 620(33.51%) were Gram-positive bacteria,1230(66.49%) were Gram-negative bacteria,25.8% of which were Escherichia coli,8.1% of which were Staphylococcus epidermidis,7.5% were Klebsiella pneumonice and 7.2% were MSSA;Statistics of drug sensibility test suggested,Gram-positive cocci isolated from the clinical issue be highly sensitive to vancomycin,teicoplanin and nitrofurantoin.They were still sensitive to rifampicin.and lower sensitive to other antibiotics.Gram-negatives were high sensitive to imipenem.They were still sensitive to piperacillin/tazobactam and the third-generation cephalosporins.CONCLUSIONS The drug resistance of the isolates is severe.It is suggested that there be ungent need for surveillance of bacterial resistance and rational use of antimicrobial agents be emphasized during clinical therapy.
