Fig. 3: Early-life lung bacterial communities.

A Relative abundance of the most abundant bacterial genera identified in lung tissue samples (present in almost 50% of samples). Sequencing of the 16S rRNA gene region was carried out on 53 lung tissue samples using the Illumina MiSeq platform. A complete list of taxa is provided in Supplementary Table S3. B Plot of bacterial genus prevalence versus relative abundance across samples. Each point corresponds to a different or unique taxon. Red dotted line represents the 50% of prevalence.
