A shotgun metagenomic investigation of the microbiota of udder cleft dermatitis in comparison to healthy skin in dairy cows
Fig 3
Data dimensionality reduction with principal component analysis (PCA) performed on the bacterial phylum (A), genus (B) and species level (C) for 49 samples from mild (n = 17) and severe (n = 19) udder cleft dermatitis and samples from skin at the fore udder attachment from healthy controls (n = 13). The (%) given for each PCA axis indicates the variation explained by that specific axis. The fourth PCA axis on genus level separated a subgroup of control samples and is presented in S2 Fig.
