Antibiotics Resistance Analysis of Pathogens Causing Nosocomial Infections in Patients after Surgery / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the distribution of nosocomial infection(NI) in patients after surgical procedures and antimicrobial resistant change of pathogens. METHODS A total of 195 strains of pathogenic bacteria isolated from the samples after surgical procedures from Jan 2006 to Dec 2006 were analyzed by WalkAway-40 system with NC31 system. RESULTS Among the 195 strains of pathogenic bacteria,there were Gram-negative bacilli(74.4%) and Gram-positive cocci(25.6%).The dominating microorganisms were Escherichia coli,Klebsiella pneumoniae,Pseudomonas aeruginosa and Staphylococcus aureus.The result showed that vancomycin and imipenem still had better activities to the bacteria. CONCLUSIONS Surgical incision infection should be monitored by some effective measures,and it is very important to prevent surgical infection and use antibiotics reasonably.
