Figure 6. Incidence of sequences homologous to ΦB124-14 and ΦB40-8 human gut metagenomes.

Percentage of individual metagenomes in which sequences homologous to φB124-14 or φB40-8 were identified (≥80% identity over ≥100 nucleotides, 1e⁻⁵ or lower). The microbial metagenomes examined were derived from individuals of European (MetaHit) [28], Japanese [8] and American [60] origin, alongside the combined viromes from 12 individuals of American descent [6]. MH MetaHit– All individuals represented in the MetaHit dataset; Jap – All individuals of Japanese origin; AM – All individuals of American descent; Virome – All viromes from individuals of American origin. B. Scatter plots illustrating the relationship between size of individual metagenomes searched and detection of sequences homologous to φB124-14. r² =  Pearson correlation co-efficient. **P<0.0001.
