title: Sputum metagenome of healthy, CF, COPD, smoker subjects
design: Sputum samples were collected from healthy smokers and non-smoking individuals, Cystic Fibrosis and Chronic Obstructive Pulmonary Disease patients. DNA was extracted from these samples without any prior removal of human DNA and the samples were whole genome shotgun sequenced for acquiring an unbiased qualitative view of the microbial community present in the different lungs.
