老年肺部感染病原菌特点分析

Analysis of Pathogen Features on Aged Patients With Lung Infection

目的 了解老年肺部感染的病原菌特点及耐药情况。 方法 标本经分离培养 ,用API细菌鉴定仪鉴定 ,用相应的ATB药敏试条进行药敏试验。 结果 G- 杆菌占 5 9.4% ,G+球菌占 2 6.7% ,真菌占 13 .9%。G- 杆菌中铜绿假单胞菌 ,肺炎克雷伯菌 ,不动杆菌属为主要菌种。肠杆菌科细菌对亚胺培南敏感性最高。G+球菌中以金黄色葡萄球菌为主 ,未发现耐万古霉素的金黄色葡萄球菌。 结论 老年肺部感染临床表现危重复杂 ,死亡率高 。

Objective To understand the pathogen features and resistance for drug in aged patients with lung infection. Methods The isolated culture were used for sputum samples. The bacteria was distinguished by API bacteria identification instrument. ATB paper was used for drug sensitive test. Results The Gram negative bacillus, Gram positive coccus and fungus were 59.4%, 26.7% and 13.9% respectively. The Pseudomonas, K.pneumoniae and Acinebacter were main bacteria in Gram negative bacillus. The enterbactericae had high sensitive for lmipenem. The staphylococcus aureus was main bacteria in Gram positive coccus in which resistance for vancomycin was not found. Conclusion The severe and complex clinic symptoms were often observed in aged patients with lung infection. These patients have high mortality. Correct and reasonable treatment depend on drug resistance test.
