Abstract
Objectives Survey of the elderly patients with bronchiectasis pathogenic bacteria distribution and drug resistance sit-uation, provide reference for clinical treatment.Methods In 329 cases of elderly patients with bronchiectasis pathogens isolated from sputum and drug sensitivity test were retrospectively investigation.Results 329 patients, 242 cases of pathogenic bacteria in-fection is positive, positive rate was 73.56%.A total of 431 strains pathogenic bacteria isolated, identified 20 kinds of pathogenic bacteria, mainly gram-negative bacteria, 73.78% ( 318 strains ) , gram positive bacteria and fungi, respectively 57 strains (13.23%) and 56 strains (12.99%).Gram-negative bacteria are mainly with klebsiella pneumoniae and pseudomonas aerugino-sa.High separation rate of gram-negative bacteria with klebsiella pneumoniae, pseudomonas aeruginosa, escherichia coli, eosinophil-ic malt pseudomonas, acinetobacter baumannii, haemophilus influenzae and the imine with haemophilus culture of the south and e-.faecalis sensitivity high, show a certain percentages of antibacterial drugs for the rest.Gram positive bacteria to penicillin, amoxicil-lin, azithromycin and clindamycin, compound ciprofloxacin new Ming and showed high resistance, and to rifampin, tetracycline, teicoplanin, vancomycin and rina thiazole amine has higher sensitivity.Conclusions In elderly patients with bronchiectasis patho-gen is given priority to with gram-negative bacteria, high prevalence and pathogen resistance, which should be clinically rational use of antimicrobial agents.关键词
