Gut microbial communities of RhCMV+ and RhCMV− animals are similar at the phylum level but cluster separately at the genus level. A Relative abundance of microbiota for each animal at the phylum level. Samples are ordered by complete-linkage clustering based on Aitchison distance. Animals are color coded as RhCMV− (red) and RhCMV+ (blue) on top of the bar graph. B PCA plot of all samples analyzed at the genus level, based on Aitchison distance
