||P.aad5872-1 middle column bottom paragraph: "It is nevertheless clear that the viral contents of the intestine are remarkably complex (ref 2, primary source 4, refs 13, 29–31). It has been estimated that the intestine contains about 100 trillion prokaryotic cells (ref 32 BNID 100555), many of which carry temperate bacteriophages in their genomes. Bacteriophages that infect these prokaryotic organisms may be ~10-fold more abundant than their host cells (BNID 113938). In addition, there is a eukaryotic virome in the asymptomatic host, with humans averaging at least 10 permanent systemic eukaryotic viral infections (primary sources)."
