Analysis of Distribution and Drug Resistance of 357 No-Pseudomonas aeruginosa / 中华医院感染学杂志

OBJECTIVE To investigate spectrum and drug resistance of No-Pseudomonas aeruginosa,to provide the basis for proper use of antibiotics and prevent patients from hospital acquired infection.METHODS API staph analysis system and the K-B agar diffusion test according to NCCLS were used to identify 357 strains of No-Pseudomonas aeruginosa and to performe drug sensitivity test.RESULTS From 2004 to 2008,357 strains of No-Pseudomonas aeruginosa were isolated.There are 233 Stenotrophomonas maltophilia strains(65.27%,233/357),55 Burkholderia cepacia strains(15.41%,55/357).Sputum was the main sourse of No-P.aeruginosa(88.52%,316/357).The isolation rate of No-P.aeruginosa was the highest in intensive care units(38.10%,136/357),the next was department of respiratorymedicine(23.53%,84/357).The results of drug susceptibility test showed that the resistance rate of No-P.aeruginosa to most drugs were higher,only the resistance rates of S.maltophilia to minocycline,gatifloxacin and levofloxacin were lower,(3.26%,20.55% and 20.83% respectively),The resistance rates of B.cepacia to meropenem,piperacillin/tazobactam and Imipenem were lower,being 29.17%,33.33% and 39.62% respectively.CONCLUSIONS The most common strains is S.maltophilia and Burkholderia cepacia,the most common site of infection is lower respiratory tract,Most strains of S.maltophilia are isolated from ICU and department of respiratory diseases.The result of drug sensitive test showed that there were high rates of multiple drug resistance in No-P.aeruginosa and treatment of No-P.aeruginosa infection should be based on the results of the drug susceptibility test.
