FIG 6.

Transmission of pegivirus and anellovirus among IDUs. (a) Maximum-likelihood phylogentic tree of human pegivirus C. Three human pegivirus genotypes are highlighted with orange, blue, and green colors. Five transmission clusters (TC1 to 5) are labeled. Pie charts to the right show the individual anellome profile within each TC (presence of each anellovirus), only top 15 abundant anelloviruses are shown. (b) Relatedness of anellovirus reads within TC versus unrelated individuals (also described in Table S3). Relatedness was compared with Wilcoxon matched-pairs signed rank test.
