Relative abundance of the 11 most abundant OTUs belonging to bacterial families within different phyla in experiment 1 (A). Relative abundance of the 11 most abundant OTUs belonging to bacterial families within different phyla in experiment 2 (B). Relative abundance of the 11 most abundant OTUs belonging to bacterial families within different phyla in experiment 3 (C). LBC-21/22, Lohmann Brown-Classic, infection at the age of 21/22 days; LBC-70/78, Lohmann Brown-Classic, infection at the age of 70/78 days; NA, OTUs without genus-level taxonomic assignment.
