Figure 4.

Gut phage richness differed between children born preterm or term. (A) Phage richness measured by the number assembled partial phage genomes per million genes; mean values 412 and 536 partial phage genomes per million genes in children born preterm and term, respectively. (B) Phage richness measured per thousand assembled contigs; mean values 2.66 and 3.11 partial phage genomes per thousand assembled contigs. (C) Gene-sharing network of assembled phage genomes (from all 41 individuals in the subgroup of this study) and reference genomes from Viral RefSeq v94 annotated with selected members of a subset of clusters. Reference genomes are in green, partial phage genomes from this study in yellow.
