摘要
目的了解呼吸内科患者下呼吸道感染病原菌的分布与耐药性,为临床医师合理用药提供科学依据。方法收集2009年1~12月诊断为下呼吸道感染的呼吸内科住院患者的痰液标本进行分离培养,并用全自动微生物分析仪进行鉴定和药敏试验。结果 214株主要病原菌的分布以革兰阴性菌为主,其中铜绿假单胞菌、鲍曼氏不动杆菌、肺炎克雷伯菌、金黄色葡萄球菌、阴沟肠杆菌、大肠埃希菌位于前6位,对常用抗生素具有较高的耐药性。结论革兰阴性菌是下呼吸道感染的主要病原菌,耐药率较高,抗生素的选用应该依据感染菌药敏分析的结果。
Objective To get the message of distribution and drug resistance of pathogenic bacterium in lower respiratory tract infection among the patients in respiration department,so to guide the reasonable use of antibiotics in practice.Methods The sputum specimens of patients from January 2009 to December 2009 were collected and separated and cultured.The identification and drug resistance of the mainly 214 pathogenic stains were analyzed using automatic microorganism analysis system.Results Gram negative bacteria were the mainly pathogenic bacteria among the 214 strains pathogenic bacterium.The former 6th predominant isolates were pseudomonas aeruginosa,baumanii,klebsiella pneumoniae,staphylococcus aureus,enterobacter cloacae,escherichia coli respectively.The strains had higher resistance to commen use antibiotics.Conclusion Gram negative bacteria were the mainly pathogenic bacteria involved in lower respiratory tract infection.The drug-resistance was high.The select of antibiotics must follow the results of the drug resistance.
