FIGURE 2.

The DNA virome at different levels in the gut microbiome of young, adult, and old female cynomolgus. (a) Venn diagram depicting the viral richness and the overlap in viral communities among young (red), adult (blue), and old (yellow) monkeys at the species level. (b) The community bar plot illustrated that the gut DNA virome from cynomolgus macaques mainly contained seven families. (c) Quantification of the relative abundance of the four families assigned to the Caudovirales order. Only the Myoviridae family was significantly enriched in the young age‐group versus the adult group (p = 0.027), not the old group. p values were determined by one‐way ANOVA followed by LSD’s multiple comparison tests. The following n values represented the number of independent animals used for statistical evaluation: young, n = 5; adult, n = 6; and old, n = 5
