OBJECTIVE To analyze the pathogenic bacteria distribution and drug resistance in inpatients of burn department,and instruct clinical application of antibiotics reasonably.METHODS Pathogenic bacteria were isolated from inpatients of burn department from 2003 to 2006.K-B slip diffusion method was taken to carry out the sensitive test.Rate of drug resistance of the pathogenic bacteria was analyzed.RESULTS Totally 1325 strains were isolated,among them 846 strains were Gram-negative bacteria,464 strains were Gram-positive ones,and 15 strains were fungi.The percentage of these three groups was 63.85%,35.02% and 1.13%,respectively.The main strains of the Gram-negative bacteria were Pseudomonas aeruginosa,Escherichia coli,Acinetobacter baumannii,Enterobacter cloacae and Klebsiella pneumoniae,and that of the Gram-positive bacteria were Staphylococcus aureus,Enterococcus and Staphylococcus epidermidis.The major strain of fungi was Candida albicans.The pathogenic bacteria tested showed high drug resistance.The detection rate of the meticillin-resistanct S.aureus(MRSA) was 82.12%.The detection rate of the ESBLs from the K.pneumoniae and the E.coli was 60.17% and 41.89%.CONCLUSIONS It was showed that the major pathogenic bacteria infected of the inpatients of burn department are Gram-negative bacteria.The pathogenic bacteria are the multidrug-resistant ones.Enhanced monitoring on pathogenic bacteria distribution and drug resistance analyses among inpatients of burn department could benefit for the guide of clinical rational administration and depression of multidrug-resistant bacteria.
