Figure 2.

Phage transmission from mothers to offspring evaluated based on metagenomic reads. (A) Relative abundance of vagina‐enriched phages in three body sites (M.vag, N.mec, and N.ora) was counted. Left panel shows the vagina‐enriched phages whose proportions in the vagina are greater than 70%, and the right panel shows transmission events of these phages between mothers and offspring. The size of bubbles represents the relative abundance of phages. (B) Relative abundance of the vagina‐enriched phages transmitted from mother's vagina to neonate. Box plots show median (black horizontal line), 25th and 75th quartiles (edge of boxes), and upper and lower extremes (whiskers). (C) Transmission events of phages in vaginally delivered mother–infant pairs.
