目的：探讨老年支气管扩张患者病原菌分布及耐药情况。方法选择老年支气管扩张患者送检的痰标本分离病原菌，进行细菌耐药性分析。结果在分离出的221株病原菌中，革兰阳性球菌57株（25.79％），革兰阴性菌151株（68．32％）。革兰阴性杆菌以铜绿假单胞菌、肺炎克雷伯菌、鲍曼不动杆菌和大肠埃希菌为主，所占比例分别为20．36％、14．02％、15．84％和9．05％；革兰阳性杆菌以金黄色葡萄球菌、表皮葡萄球菌和肺炎链球菌为主，所占比例分别为9．50％、8．60％和7．69％；其他为真菌，所占比例为5．88％。结论老年支气管扩张患者病原菌以革兰阴性菌为主，其中铜绿假单胞菌排在首位，合理选用抗菌药物对减少耐药率的产生有重要作用。

Objective To investigate the distribution of pathogens in elderly patients with bronchiectasis and drug resistance.Methods Elderly hospital patients with bronchiectasis were selected,pathogens isolated from sputum specimens and analysis of bacterial resistance.Results 221 strain of pathogen were isolated,of gram -positive bacte-ria 57 strain(25.79%),gram -negative bacteria 151 strain(68.32%);gram -negative bacteria Pseudomonas aerug-inosa pneumonia Klebsiella,Acinetobacter baumannii and Escherichia coli -based was 20.36%,14.02%,15.84%and 9.05% respectively;gram -negative bacteria Staphylococcus aureus,Staphylococcus epidermidis and Streptococ-cus pneumoniae based was 9.50%,8.60% and 7.69% respectively;other fungi,the proportion was 5.88%. Conclusion Elderly patients with bronchiectasis distribution of pathogens to the highest proportion of gram -negative bacteria,including Pseudomonas aeruginosa in the first row,tip rational use of antimicrobial drugs in reducing the rate of drug resistance plays an important role.
