Figure 2

Weighted graphical representation of Famint families shared between bacterial hosts. Bacterial strains were grouped at the genus level unless there was a single representative at the strain or the species level. These groups of bacteria were represented in terms of the Famint families they contain. The graph was built as described in Methods. Nodes are bacterial genera, species or strains. They are linked by an edge if sharing Famint families. The thickness of the edges is proportional to the number of families shared by linked nodes. Note the tight grouping of Enterobacteria and Firmicutes.
