16S amplicon sequencing of human gut:  infant stool
Fecal samples were collected by the patients using swabs or tubes to sample feces deposited into a toilet hat immediately after production, then stored frozen at approximately 20C. Samples were subsequently transferred to the laboratory and stored at 80C until used. Samples from patients were obtained prior to antibiotic therapy and between 1 to 60 days of study, with daily collection until day 6, and thereafter collection every 5 days until day 60.
