Fig. 4From: Systematic profiling of the chicken gut microbiome reveals dietary supplementation with antibiotics alters expression of multiple microbial pathways with minimal impact on community structureOverview of metatranscriptomic analysis. A Rarefaction analysis showing the number of enzymes detected (as defined by unique EC numbers) as a function of read depth for ceca and jejunum samples. B Principal component analysis (PCA) based on annotated microbial gene expression in ceca samples. Each node represents an individual ceca sample (see inset key for type of sample). C Overlap of significantly differentially expressed genes across ceca samples, comparing AGP treatments (left) and diet (right)Back to article page
