Abstract:
OBJECTIVE To investigate the resistance status of pathogens from surgical incision infection.METHODS The secretion of infected wounds was cultured to detect pathogens by routine methods from Jan 2001 to Dec 2006.The identifications and antimicrobial-susceptible tests of pathogens causing incision infection were determined by Full Automated Analyzer.All data were analyzed retrospectively.RESULTS A total of 246 pathogen strains were cultured from the secretion of surgical incision infection in 6 years,of which Gram-negative bacilli,Gram-positive cocci and fungi accounted for 57.7%,34.1% and 8.2%,respectively.The first place of isolates was Escherichia coli,followed by Staphylococcus aureus,Pseudomonas aeruginosa,Klebsiella pneumoniae,Acinetobacter baumannii,etc.74.5% of S.aureus isolates and 83.3% of S.epidermidis isolates were resistant to oxacillin.45.1% of E.coli of the isolates and 35.0% of isolates of K.pneumoniae were extended-spectrum ?-lactamases producing.Almost all of the detected resistant strains showed serious multiple resistance.Vancomycin and imipenem still had better activity for antimicrobial multiple resistant bacteria.CONCLUSIONS Surgical incision infection is serious.Infection surveillance should be taken to control surgical infection.Pathogens infected surgical incision are multi-resistant to antibiotics.
