About this study

Qualified sputum samples from bronchiectasis patients were collected regularly every month for three consecutive years to analyze the microbiome changes of lower respiratory tract of bronchiectasis patients by metagenomic sequencing. Pseudomonas aeruginosa was isolated and the whole genome was sequenced to analyze the adaptive evolution,including virulence, quorum sensing and drug resistance under host pressure. The aim of the study is to clarify the rule of microflora colonization distribution and adaptive evolution in the lower respiratory tract of patients with bronchiectasis, to predict the acute attack and prognosis of patients with microbiome changes, and to find more new prevention and treatment methods by adjusting the microbiome of the lower respiratory tract.
