FIG 1.

Classification into distinct compositional types of the gut microbiota of dogs and cats. The cladogram on the left displays the hierarchical clustering of the collected samples based on their average 16S rRNA gene microbial profiles. The bar plot in the center depicts the abundance of the 10 most representative microbial taxa of the considered samples. The numbers on the right correspond to the names of collected samples. The colored dotted rectangles separate samples into the six identified gut community state types (GCSTs) whose names are reported on the right with the same GCST color code.
