Distribution of the viral community across individual bees and stability over space and time. (A) Detection of VCs in 73 bacterial metagenomes of individual honey bees from Switzerland and Japan. Per-base per-contig coverage of mapped reads to VCs is depicted as a heatmap of relative abundances in log10 scale (log10 values below zero indicate coverage below 1×, and −2 indicates no reads recruited). Samples are ordered according to country (Switzerland and Japan) and colony (black and gray bars), and for the Swiss samples also according to age (Y, young, M, middle age, O, old; see ref. 32). VCs are sorted according to lifestyle (lytic vs. temperate). (B) Incidences of VCs across individual bees from Switzerland and Japan. VC order is the same in the two panels.
