Figure 3. Phage–host prediction based on co-occurrence across metagenomes.

Unrooted co-occurrence cladogram of correlated depth profiles across 151 HMP faecal metagenomes16 of the crAssphage, two known Bacteroides fragilis-infecting phages22,26, and 404 potential hosts. Colours indicate bacterial phyla. The phages are indicated with blue dashed lines. See Supplementary Fig. 7 for the fully annotated figure.
