Abstract Object To study the etiology of COPD sufferer and compare the drug sensitivity with whole hospital. Method Identify the bacterium by VITEK,detect the drug sensitivity、ESBLs and MRS with K-B method according to NCCLS, statistic analysis with WHONET 5.4. Result In positive samples, Klebsiella pneumoniae、Pseudomonas aeruginosa and Escherichia coli are responsible for the first、second and the third，Gram-positive bacterium are mostly consisted of Staphylococcus and Enterococcus，ESBLs and MRS are respectively 78.5%,76.1%. Fisher probabilities shows the drug resistance ratio of Gram-negative bacterium is higher than the whole hospital evidently. Conclusion In COPD sufferer，Gram-negative bacterium are in the ascendant and the drug resistance ratio is higher than whole hospital；high detection of ESBLs and MRS means the high drug resistance of the bacterium.
