From: The sputum microbiome associated with different sub-types of AECOPD in a Chinese cohort
The sputum microbiome at the genus level. Each bar shows the relative abundance of individual (a) or average (b) samples collected at AECOPD, healthy controls, recovery and Stable. Across all samples, the sum of average relative abundance of top30 genera was over 96%. Health Control: subjects without any clinical signs; AECOPD: acute exacerbations of chronic obstructive pulmonary disease; Recovery: the patient recovering from exacerbation treatment; Stable: stable period over 8 weeks free of an AECOPD
