title: Metagenomic sequencing of human gut feces: adult
design: This experiment aimed to compare the gut virome composition between rheumatoid arthritis(RA) patients and healthy individuals.  Fecal samples were collected from 16 RA patients and 11 healthy controls.  Viral particles were enriched by 0.67-m filtration and DNase treatment to remove host DNA.  Viral DNA was extracted using the QIAamp Viral DNA Mini Kit.
