(A) phylogenetic diversity (PD) and (B) Shannon diversity of each GI site from the six mice.
Figure 2.
Relative abundance of sequences belonging to different bacterial phyla.
Sequences that could not be classified into any known group were assigned as ‘Unknown’. Sto: Stomach samples; Duo: Duodenum samples; Jej: Jejunum samples; Ile: Ileum samples; Cec: Cecum samples; Col: Colon samples; Fec: Feces samples. The number following the abbreviations stands for the mouse number. For example, Cec1, Cec2, Cec3, Cec4, Cec5, and Cec6 stands for the Cecum sample from the 1st, 2nd, 3rd, 4th, 5th and 6th mouse.

Relative abundance of sequences belonging to different bacterial Class.

Contribution of different taxonomic groups to separation of samples based on phylogenetic information.
The contribution of each group is represented by the size of the circles (grey) overlaid onto a PCoA of unweighted UniFrac distances for all samples within mice digestive tract.
