肺结核患者痰标本凝固酶阴性葡萄球菌分析

Analysis of Coagulase Negative staphylococcus from Sputum

目的:了解凝固酶阴性葡萄球菌(CNS)的感染情况及耐药现状。方法:用经典生化鉴定方法,对临床分离到的132株CNS进行种类鉴定和药敏试验。结果:132株CNS中表皮葡萄球菌占62.9%,溶血葡萄球菌占19.7%。对苯唑西林耐药率74.2%,对青霉素的耐药率92.2%。结论:表皮葡萄球菌和溶血性葡萄球菌是临床CNS的主要致病菌,对多种抗生素耐药。治疗由CNS引起的感染应以药敏试验结果为依据。

Objective：To find out infection of coagulase -negative staphylococcus and their multiple drug resistance status and control nosocomial infections caused by CNS. Methods：Main classic biochemistry was used for identification and susceptivity testing. Results： Of identified CNS, S. Epidenmidis accounted for 62. 9 % and S. Haemolyticus accounted for 19.7 %. The drug resistance of penicillin was 92.2 % and OX was 74.2%. Conclusion：To fight the CNS infection, the choice should be based on the drug susceptivity testing. Advisable drugs for CNS infections include vancomycin, rifampin and so on.
