Fig. 1From: Insights into the respiratory tract microbiota of patients with cystic fibrosis during early Pseudomonas aeruginosa colonizationPhylogenetic tree of the bacterial diversity of core CF pulmonary microbiota. This figure was created using the interactive Tree Of Life (iTOL) (Letunic and Bork 2007). The inner circle shows genera colored by phylum or Proteobacteria class. Each node represents a core OTU shared among 50 % of the samples at a relative abundance >0.1 % of the total bacterial community. The outer bars represent the relative abundance of each OTU for the 5 CF patients.Back to article page
