Abstract: 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.
