Bronchial and peripheral lung microbiota taxa are similar. Taxonomic assignments for all sequences were determined using Greengenes version 13_8. Each site is represented by a bar, with color indicating genus-level taxonomic assignment and length indicating relative abundance. Taxa present at < 1% overall relative abundance are represented in white. Streptococcus (blue) was the most common genus overall (representing nearly 19% of all DNA sequences identified), and the most common genus in the oral samples, bronchial samples, and peripheral lung samples (at 38, 14, and 14%, respectively). In contrast, the nasal samples contained 1.6% Streptococcal sequences. Nasal samples were dominated by Corynebacterium (red, 42% of sequences), which was found as 5% of oral sequences. Corynebacterium represented 6.6 and 9.4% of bronchial and peripheral lung sequences, respectively
