下呼吸道感染者铜绿假单胞菌的分离与耐药性分析

Separation and Drug Resistance Anaiysis of Pseudomonas Aeruginosa in Patients With Lower Respiratory Trace Infection

目的了解我院下呼吸道感染患者铜绿假单胞菌的分离现状及其耐药趋势。方法对2005年10月～2007年8月期间下呼吸道感染患者送检标本中分离的182株铜绿假单胞菌进行药敏试验进行统计分析。结果下呼吸道标本1409例,共分离出病原菌1031株,铜绿假单胞菌182株,占其阳性率17.65%;铜绿假单胞菌药敏结果表明对庆大霉素、复方新诺明、头胞噻肟、加替沙星等抗菌药物耐药。结论铜绿假单胞菌的感染与耐药问题已十分突出,了解耐药现状,指导临床合理用药。

Objective To understand Present condition of separation of Pseudomonas aeruginosa and its drug - resistant tendercy in patients with lower respiratory trace infection in our hospital. Methods To make a statistical analysis of durg sensitive tests of 182 strains of Pseudomonas aeruginosa form thos samples of patients with lower respiratory trace infection detected from October 2005 to August 2007. Results 1031 strains of pathogenic bacteria were separated from 1409 sample of lower respiratory trace tract ,and pseudomonas aeruginosa 182 strains and 17.65% of them are PA ,results of drug sensitive test indicate that Paare resistant to gentamycin CN SMZ CTX GAT etc. Conclusion The infection and drug resistance of pare wery severe now, it isbeneficial to rational use of drugs to keep abreast of current drug - resistant condition.
